ITU IMT-2000 3G CDMA2000 Releases

Currently there are 3 major formal 3GPP2 "completed" (functionally frozen) ITU IMT2000 CDMA2000 Standards Releases.

CDMA2000         TIA/EIA Original
Release Publish Date

* Release A March 2000
* Release B April 2002
* Release C May 2002


Release D is currently being defined in 3GPP2 and some aspects of it are being coordinated with 3GPP, which is concurrently defining 3GSM Release 6, to promote harmonization and interoperability between the 2 primary 3G standards in an All-IP environment.

CDMA2000 Release A was "completed" in March 2000, and officially approved as one of the 5 ITU IMT-2000 3G Radio Technologies at the May 2000 meeting of the Radio Assembly in Istanbul, Turkey:

3gpp2.org

The foundation for CDMA2000 Release A was TIA/EIA/IS-2000, Release 0, aka 1xRTT, aka CDMA2000 phase one, aka IS-95C, aka CDMA2000 1X, which was approved for publication by the Telecommunications Industry Association (TIA) subcommittee TR45.5 on July 12, 1999:

cdg.org

CDG referred to the publication of CDMA2000 Release 0, as "achieving the final milestone in the standardization process for the international 3G standard," but it was an early milestone, and hardly a "final milestone."

CDMA2000 Release 0 is not an ITU IMT-2000 3G standard and additional work had to be done between initial publication and the "completion" of CDMA2000 Release A, based on compliance with OHG G3G guidelines, for acceptance of Release A as an ITU IMT-2000 3G standard.

CDMA2000 Release 0 focuses on defining 1xRTT utilizing "Spreading Rate 1" which allows peak data transmission rates of 153 kbps. CDMA2000 Release 0 focuses on 1xRTT utilizing "Spreading Rate 1" and/or "Spreading Rate 3" which optionally permits peak data transmission rates of 314 kbps (less overhead).

The 46 CDMA2000 1X commercial networks currently deployed across Asia, the Americas and Europe today are all compliant with CDMA2000 Release 0, not CDMA2000 Release A, although it is entirely possible that some enhancements to 0 included in Release A, are included in deployed implementations. This is particularly true of glitches that were debugged in lab and commercial field trials that commenced in Seoul, Korea on October 1, 2000. These corrections and updates are contained in the appendices to the final publication of CDMA2000 Release A.

Shortly after Release A published, 3GPP2 focused attention on standardizing 1x Evolution Phase 1 (1xEV Data Only) which was based on a modified version of Qualcomm's CDM/TDM hybrid called High Data Rate (HDR). 1xEV-DO essentially offered most of what 3xRTT was intended to offer but accomplishes it within an existing 1.25-megahertz CDMA carrier rather than 3 aggregated carriers.

The CDMA2000 High Rate Packet Data Air Interface Specification (TIA/EIA/IS-856) published separately in November 2000 and was subsequently accepted as an ITU IMT-2000 3G standard under the IMT-MC CDMA2000 Release A umbrella (although it is not part of Release A.

qualcomm.com

Concurrently discussion began on standardizing 1x Evolution Phase 2 which would integrate voice and data in a single carrier, at speeds in excess of the ITU's recommendations of 2 Mbps in a fixed environment.

Motorola had earlier announced its own competing proposal at CTIA 2000 where Lucent demonstrated Qualcomm's HDR. Motorola's technology–1X Plus–offered first phase data rates of 1.38 Mbps peak throughput on a single 1.25-megahertz CDMA carrier, later moving to 5 Mbps in a fixed environment. Seven other companies announced proposals of their own for integrated voice and data (LGE, LinkAir, Lucent, Nortel, Qualcomm, Samsung, and Tantivity). Nokia, pooled resources and joined forces with Motorola and their combined proposal renamed 1EXTREME and TI, and Altera backed it. Motorola proposal which was renamed 1EXTREME. L3NQS: Proposed by Lucent, LGEl, LSI, Nortel, Qualcomm and Samsung, joined forces to back a combined L3NQS proposal based on standards work already done for 1X technology and 1XEV-DO.

Sprint PCS, ALLTel, Qwest, Bell Mobility, Nextel, and LGT were the primary backers of 1xEV-DV, and work on that Release C standard occupied the majority of 3GPP2's efforts from the summer of 2001 through publication in May 2002.

Consensus was reached on the baseline framework for CDMA2000 1xEV-DV (data and voice) by 3GPP2 in October 2001. Nominally the framework is a harmonization of different proposals and concepts from many of the 3GPP2 member companies. In actuality the basic framework is based on .... The 1xEV-DV standard published in March 2002 and obtained ITU 3G approval in May 2002.

The baseline framework was decided in time for an initial joint 3G Harmonization meeting in November 2001 which included discussions between 3GPP and 3GPP2 about their respective techniques for achieving higher data rates on their 3G systems. The 3GPP project for achieving higher data rates has been termed: HSDPA (High Speed Downlink Packet Access) and the 3GPP2 project for achieving higher data rates has been termed 1xEV-DV (CDMA2000 1x Evolution for Data & Voice). This technology evolution will provide integrated voice with simultaneous high-speed packet data, video and video conferencing capabilities and 1xEV-DV will be backward compatible with IS-95A/B and CDMA2000 1x, allowing for a "graceful operator evolution for their CDMA2000 systems".

Finding a good comprehensive and concise summary of the components of each of the CDMA2000 Releases is extremely difficult.

This "Release A System Capability Guide" defines Release A Objectives on pages 11 and 12, but please note that publication date is January 2000 so it may not reflect capabilities of the matured standard which had modifications made through October 2001 and published in the spring of 2002:

This "Release B System Capability Guide" defines Release B Objectives on pages 13 and 14, but please note that publication date is 14 June 2001 so it may not reflect capabilities of the matured standard which had modifications made through the spring of 2002 when it finally published:

3gpp2.org

In July 2002 Qualcomm created a whitepaper that they subsequently published in October 2002, that defines the basic characteristics of each IMT-2000 IS-2000 release, and the differences between them. It does not address 1xRTT spreading rate 3 data transmission speeds (307 kbps - 288 kbps less overhead) or the spreading rate that would bump 1xRTT to 614 kbps, or 3xRTT which would aggregate 3 carriers at 614 kbps and allow 1xRTT to be in full compliance however theoretically (rather than meeting minimum requirements) with the ITU IMT requirements for 3G. The complete whitepaper is here:

The following text is abstracted from that referenced Qualcomm whitepaper:

CDMA2000 1X Enhancements

Major new enhancements that CDMA2000 1X is offering include:

* Increasing voice capacity from 22 TCH per sector per carrier in cdmaOne to
35 TCH per sector per carrier (current phase), increasing to 49 TCH per sector
per carrier in 2003/2004 with SMV vocoder (mode2)

* “Always On” peak packet data rate of 153 kbps (current phase), increasing to
307 kbps in 2003/2004 (1xEV-DO delivers a peak data rate of 2.4 Mbps)

* Connectivity to ANSI-41, GSM-MAP, and All-IP networks

* Various bands and bandwidths of operation in support of different operator needs: 450, 800, 900, 1700, 1800, 1900, and 2100 MHz (there are no commercial
networks in 900 and 1800 MHz band today)

* Fully backward compatible with cdmaOne systems

* Improved service multiplexing and QoS management

* Flexible channel structure in support of multiple services with various QoS and
variable transmission rates

* Today’s commercial CDMA20001X networks (phase 1) support a peak data rate of 153.6 kbps. The theoretical maximum data rate supported by the standard is 628 kbps, and it is achieved by having 2 SCH at 307 kbps while FCH supports an additional 14.4 kbps of data traffic. While some of the CDMA2000 ASICs support 307 kbps, handsets delivering this data rate have not become commercial yet. Some of today’s commercial handsets deliver 153 kbps with an average data rate of 60 to 90 kbps on 1X and 2.4 Mbps on 1xEV-DO with an average data rate of 650 to 1400 kbps.

2000: The Evolution of 1x Evolution: From HDR to 1xEV-DO and 1xEV-DV

>> Dedicated to Data

>> HDR Offers Service Providers the Data speeds for Evolution to 3G

Wireless Review

In the drive to accelerate wireless-data throughput, technologists have turned speed and spectral efficiency into an art form. And in the case of high data rate (HDR), Qualcomm is the Picasso of proficiency, the Van Gogh of velocity. Qualcomm's patented HDR technology was approved this summer by the CDMA Development Group (CDG) as Phase I of 1XEV - a 3G technology with a peak data rate of 2.4Mb/s on a data-only channel. (Phase II will encompass data and voice improvements, but has yet to be decided.) Sprint PCS and Verizon Wireless are conducting trials of HDR-based solutions, as are KDDI in Japan and KT Freetel in Korea.

This 3G advancement will enable networks to efficiently carry next-generation data services and mobile Internet applications to subscribers. Vendors are providing HDR primarily as a channel-card upgrade that along with new software will allow providers to build on their current 1X investments, hence the name "1XEV," for evolution.

The business case is clear: 1XEV uses current 1X equipment as a springboard to faster data rates and saves providers money and spectrum along the way.

Talking 'Bout an Evolution

When the wireless industry first started talking about transmitting more than voice across digital networks, speeds were incredibly slow - around 14.4kb/s using the IS-95A standard, which evolved to IS-95B (64.4kb/s) and then 1X - also called 1XRTT (144kb/s).

The benefits provided by these standards included doubling voice capacity and increasing data rates. And the market is eagerly anticipating the 2001 roll-out of 144kb/s networks by major providers.

But engineers at Qualcomm decided there were still problems to be solved, said Kimberly Kleber, director of product marketing for HDR.

"What Qualcomm started looking at was the voice channel that is being shared as a data channel," Kleber said. "And the question that came to some of our engineers then was, 'How can we get a higher data speed than what is going to be achieved in this shared 1X mode?' and 'How can we ensure higher data speeds?' The engineers started really focusing on the fact that when you separate voice and data, you have certain benefits. You're no longer concerned about latency requirements of voice. Digital has done a great job of making sure the voice quality is maintained. But in doing that, the overhead that's required for that channel to maintain that voice quality essentially degrades the ability to handle data efficiently and optimally. With HDR, what happens is we take a dedicated 1.25MHz channel, a narrowband channel, and optimize it for packet data. By optimizing it for packet data, we could then allow the channel to burst to any single user at a given instant and send the full power of that sector."

The bursts are sent in 1.67ms packets at the peak rate of 2.4Mb/s, Kleber said. Average throughput rates are closer to 1Mb/s, according to service providers testing the technology.

"You don't get data that fast sitting at a desk," Kleber said. "It's a compelling technology. And HDR is a technology that can bring this wireless-Internet revolution quicker."

A big reason is spectral efficiency. By transmitting at data rates of 2.4Mb/s over the 1.25MHz of spectrum, providers avoid having to upgrade to a wideband 5MHz channel, Kleber explained.

The 1XEV technology is being tested now and should begin deployment in late 2001 or 2002, she said.

Provider Proving Ground

Over the last two years, Sprint PCS has found through trials that 1XRTT will yield a tenfold increase in data rates - from 14.4kb/s to 144kb/s - as well as improved voice capacity and battery performance on handsets.

The provider plans to roll out 1XRTT at the end of 2001, according to Oliver Valente, Sprint PCS CTO.

"What 1XEV will do is take us to the next plateau of data, which is up to 2.4Mb/s," Valente said. "1XEV is based on HDR, and we had HDR in our labs a year ago and liked what we saw. But we had issues with making sure it fit nicely with the 1X evolution path, in terms of upgradeability to our network.

Rather than installing all new radio infrastructure, which was what was originally envisioned with HDR, Sprint PCS needed a more cost-effective upgrade, he said.

Through standards discussions with other providers and vendors, an agreement was reached on the most effective way to bridge HDR into the 1X evolution path, Valente said.

"The goal is to try and have it standardized by the end of the year and start seeing commercial products in '02 some time," he said.

In order to maximize its investment in 1X infrastructure, Sprint PCS is using a multicarrier-base-station approach for its 1XEV solution.

Qualcomm's Kleber explained that a vendor such as Lucent can take an existing multicarrier base station and install both 1X and HDR channel cards, thus housing both types of technology.

Ed Chao, Lucent senior manager for 3G CDMA data, said this is exactly how the company upgrades its Flexent base station, which Sprint currently is using for 1X and will continue to use for 1XEV.

"Upgrading is very simple," Chao said. "We use the existing shelves and add a channel card - a simple card upgrade as well as some software in the same base station."

Although Sprint now is committed to 1XEV, the decision was not always clear, Valente said.

"Qualcomm was the one that initially developed HDR," he said. "But there were some competing proposals put on the table by Motorola with 1Xtreme. We liked a lot of those ideas, but we really have sort of put those in a second phase of 1XEV. It hadn't been as developed as HDR. We were concerned that if we focused on 1Xtreme that we would lose time to market. What we've said is we liked a lot of those concepts and are trying to incorporate those into the next generation, which is beyond 1XEV. We've worked with Qualcomm, Lucent, Nortel, Motorola, Samsung, Ericsson, just to name a few of the vendors involved in these discussions to date."

Beyond HDR

Phase II of the CDG's standards process will determine what technology will encompass both data and voice, hence one of its working names, 1XDV. However, the technology that will be chosen for Phase II is far from decided, according to Qualcomm's Kleber.

"Phase II, at this point, is being evaluated and doesn't have a solution yet," she said. "(The CDG) is evaluating 1Xtreme or LAS-CDMA (large area synchronized-CDMA) or an evolution of HDR. There will be a technology that will fill this Phase II, which will be totally new. And Phase II is intended to give you high data speeds and voice."

"Right now, Motorola, Nokia and others are positioning their technology proposals as the eventual baseline for the DV technology, the second phase," said Neal Campbell, Motorola director of CDMA product operations, adding that the DV phase is scheduled for a draft standard for May of next year. Motorola's proposed 1Xtreme technology will be considered along with others - many of which reach data speeds of 5Mb/s or faster.

"The DO (data only) space will allow for 600kb/s average data rates with peak rates of better than 2Mb/s," Campbell said. "For the DV proposals - at least I can speak of (1Xtreme) and the LinkAir (LAS-CDMA) technology - those proposals are trialing and proposing to get to 5Mb/s peak data rates with average data rates of 1Mb/s."

According to LinkAir, which conducted a trial call on LAS-CDMA Aug. 15 in Beijing, the technology offers 20 times the voice coverage of existing 2G networks, while increasing data speeds to 5.53Mb/s. LAS-CDMA is compatible with GSM and CDMA networks, as well as the major international 3G standards. And LinkAir refers to it as a bridge standard between 3G and 4G.

As with 1XEV, the Phase II solution - whether it ends up being 1Xtreme or LAS-CDMA - could be installed on existing 1X multicarrier base stations, needing only a channel card and software upgrade.

Although existing network infrastructure can be leveraged for Phase II, providers likely will need additional spectrum, Campbell said.

"When you look at the data rates (5Mb/s) that we are proposing on such a narrow channel (1.25MHz), you do start asking yourself, 'What is the viability or necessity for a 5MHz-wide channel for wireless communications?'" Campbell said. "If we can play out these data rates of 5Mb/s peak and 1Mb/s average that we believe is quite possible, my guess is what we will start to see is a move to greater spectrum trunks, from 1.25MHz carriers to the wider carriers to further increase the capacity and capabilities."

Wireless data's broad popularity remains to be shown, however. Only time will tell what technology truly will match consumer demand. <<

>> Taking CDMA's Scenic Route To 3G Services

Mark Dziatkiewicz
Wireless Week
November 20, 2000

wirelessweek.com

Taking a trip often involves choosing between a direct highway route or the scenic back roads. Both ways get you there eventually, but the out-of-the-way path can open your eyes to sights and experiences you would otherwise miss.

So it is for CDMA operators on the road to third-generation services. Choice is the operative word for CDMA operators, who are looking for cost-effective, standardized alternatives to reaching their 3G wireless objectives.

The CDMA road to 3G has taken a few turns during the past several months. And while carriers could take the direct route on highway 3xRTT, the scenic route is getting more interesting every day. If speed isn't the only priority, it could just be the best way to go.

Who Wants Dick Tracy?

Third-generation wireless is all about hard-to-believe data rates and outrageous applications like a Dick Tracy video on your wrist. But if 3G services can't be offered cost effectively to the subscriber, does it matter what the technology is capable of?

In May 2000, the CDMA community took steps toward getting more bang from its cdma2000 upgrade bucks by adopting a high-speed data-only addition dubbed 1xEV-DO, or 1x Evolution-Data Only. 1xEV-DO offers most of what 3xRTT does but accomplishes it within the existing 1.25-megahertz CDMA carrier.

For operators, that is a big step toward cost-effective high-speed data because it avoids the hardware/software upgrade changes required with the 5-megahertz carrier of cdma2000 3x. "If the reason to go to 3xRTT is to provide high-speed data, but you can use the same bandwidth with 1xEV-DO and use less spectrum, it will give you a cost advantage," says Yusuke Higashi, CDMA product line manager at Nortel.

1xEV-DO evolved from the Qualcomm High Data Rate proposal proffered in late 1999. HDR demonstrated peak data rates above 1.8 megabits per second in a 1.25-megahertz carrier, but it was a data-only technology.

Motorola, on the other hand, announced its own competing proposal at CTIA 2000. Its technology–1X Plus–offered first phase data rates of 1.38 Mbps peak throughput on a single 1.25-megahertz CDMA carrier, later moving to 5 Mbps in a fixed environment.

In the end, the CDMA community chose the Qualcomm approach with modifications. Time to market and catching the high-speed mobile Internet wave were motivating factors to go with HDR, according to Ed Chao, Lucent's senior manager, 3G and data product management. The opportunity to offer high-speed data rates that met or even exceeded those capable in GSM and TDMA 3G proposals–in a similar time frame and without costly hardware changes–was too good to pass up.

"Qualcomm had been working on [HDR] for over three years," Chao says. "They had been trialing the technology in San Diego and had done a lot of proof of concept." Because Motorola's technology proposal was not as far along, the CDMA Development Group and its members opted for Qualcomm's approach.

But 1xEV-DO isn't an exact clone of HDR. Because HDR was designed for data only, it required a separate CDMA carrier with no voice integration. While the second carrier was something operators were willing to live with in the short term, the lack of voice integration wasn't.

Relying on a separate carrier would have necessitated stand-alone devices on a high-speed data network, separate from the carriers' 1xRTT voice networks. The business case wasn't as appealing to operators, "because if they can't inter-work and communicate there is less value for operators to provide the services," Higashi says.

For that reason, a number of modifications were made in the evolution to 1xEV-DO, including one to increase traffic throughput and another for interoperability with 1xRTT. The latter acknowledges the direction and importance of Motorola's 1X Plus technology.

In an integrated solution, a terminal could offer both voice and data with hand-off capabilities. For example, the subscriber could be involved in a high-speed data session using the 1xEV-DO network when a voice call comes through. The data session then could be handed off to a 1xRTT CDMA carrier so the data session continues and the subscriber picks up the voice call, without involving two separate CDMA carriers.

"The implication is that the high-speed data application in progress might get flow control because 1X only supports a 144 kilobit-per-second data rate vs. the HDR rate," says Phil Hester, director of technical product marketing at Ericsson.

Providing the multiservice capability was an important concession and strategic modification. In some respects it offers the best of both the voice and data worlds. With 1xEV-DO, the separate spectrum allocation takes advantage of data's characteristics to provide maximum efficiency, which is a nod to Qualcomm's original premise. And the inter-working between voice and data reflects the operators' wishes and market realities.

The phase one standard was scheduled for publication at the end of October, enabling field trials in January 2001. Manufacturers suggest commercial deployments will commence during 2002.

Focusing On Phase Two

At the same time, work continues on phase two of 1xEV, where the objective once again is to integrate phase one capabilities on the "same" CDMA carrier while retaining the ability to maintain packet data services on a separate carrier.

Peak data rates get bumped up to 1.25 Mbps in both directions (see chart) with average rates of 600 kbps in a fully loaded system with all users moving at vehicular speed. Phase one provided asymmetric data rates in all categories.

Other objectives in phase two include three modes of traffic delivery–real-time, non-real-time and a mixture of the two–and another doubling of voice service spectral efficiency. But most importantly, the standard should provide graceful evolution from existing CDMA platforms with minimal cost upgrades.

It's a tall order, but since time to market isn't as critical, the requirements have spawned three proposals to date, coming from Motorola, Lucent and LinkAir.

Motorola partnered with Nokia and repackaged 1X Plus as 1XTREME. "Integration of voice and data is the preferred method, so we've refocused our efforts on phase two requirements," says Neal Campbell, director of CDMA product operators for Motorola's Network Solutions Sector.

One of the primary challenges in the integrated approach is packetized voice and handling the basic differences between voice and data. Voice needs a continuous stream while data uses bursts, so allocation issues exist.

Combining both types of traffic within the same bandwidth will require unique approaches in order to achieve cost efficiency while maintaining the necessary voice and data throughput. There seems to be agreement "that integrating voice and data is the right thing to do going forward, but no one is sure of the right way to do it," Nortel's Higashi says.

Motorola could have an early lead with phase two because it's been working for a while on an integrated approach. But still there are a number of requirements that 1XTREME would need to support, "and some of those things are pretty dicey," Ericsson's Hester adds.

Ericsson doesn't have a submission of its own, so it is closely examining what's already on the table. Hester says one of the toughest requirements is to provide backwards compatibility with everything CDMA offers to date. And providing another doubling of voice capacity isn't trivial either.

He indicates that Motorola uses some incredible modulation schemes to achieve its 5 Mbps burst capacity but suggests that throughput often suffers as a result. And there also are concerns about the required proximity between base station and terminal to support these extraordinary data rates.

Nortel isn't bound to any proposal so far either but intends to see the process move forward in a way that is beneficial to everyone. Higashi points out that the current proposals deal with the radio portion only, and that alone "won't give you a cost advantage." The overall network solution is just as important.

Lucent submitted its proposal to the 3GPP2 (third-generation partnership program 2) standards group last month, according to Chao. Lucent was an early Qualcomm HDR supporter and is working closely with Motorola and Nokia to resolve differences between proposals.

The 1xEV-DV dark horse is LinkAir, a startup founded by one of the inventors of CDMA. LinkAir patented LAS-CDMA (large area synchronized-code division multiple access), which provides up to six times greater capacity than that of cdma2000, and the company hopes to position the technology as CDMA's next evolution.

With Internet protocol technology at its core, LAS-CDMA already incorporates 1xEV-DV's integrated voice and data requirements. And based on patented spreading technology, it eliminates the interference-limiting aspects of CDMA technology, according to a company white paper.

It also promises backward compatibility with existing wireless systems such as IS-95, IS-41 and GSM Mobility Application Part. But despite being a more efficient CDMA, some suggest it could have difficulty maintaining the backward and forward compatibility due to the nature of its implementation.

Whatever direction 1xEV-DO takes, it likely will undergo a few iterations before a final solution emerges. But an overall commitment exists on the part of manufacturers and operators to drive CDMA technology forward, while driving costs downward.

No single road exists to implementing 3G technology, particularly for CDMA operators. But sometimes the scenic route is simply the better way to go. <<

The CDMA2000 High Rate Packet Data Air Interface Specification (TIA/EIA/IS-856) published in November 2000 and was subsequently accepted as an ITU IMT-2000 3G standard under the IMT-MC CDMA2000 Release A umbrella (although it is not part of Release A.

Sprint PCS' CTO takes on 3G, evolving what is known and preparing for the unknown.

Sprint PCS began conducting pre-commercial 3G field testing more than a year ago. Part of the ongoing trial is to make sure 1X equipment works with the existing network architecture. Part of it is to test hardware and software in a pre-commercial state. Part of it is to simulate how the network will perform with customers.

The goal is to be prepared for every eventuality before going commercial. However, how do you prepare if there are no precedents, no models and no predictability in equipment, performance or customer demands?

That's Oliver Valente's job as Sprint PCS CTO: Make 3G work in a nationwide network, come what may. And that may be a gradual ramp-up of customers, or it could be a flood. It may be a doubling of monthly minutes of network use from today's multibillion to two times that, three times that … who knows? It may be a lot of things, none of which is certain until you are in the throes of it.

First Steps

At its Integration Lab in Lenexa, KS, Sprint PCS launched its first cdma2000 1X trial efforts with Samsung Telecommunications America, 3Com and Qualcomm . The trial tested the integration of voice and data in one cell at the same radio frequency. The carrier wanted to know if it could achieve 144kb/s with 35 full-rate voice calls at the same time.

The system included three fully integrated ATM-ready base stations, a BSC, base-station management and an MSC.

In a cdma2000 1X network, the BSC connects directly via a radio-port interface to a packet-data serving node (PDSN). The PDSN performs the traffic-integration function similar to that handled by circuit switches. It uses authentication, accounting and administration servers for user authentication and traffic management, and then forwards traffic to the Internet.

3Com provided the PDSN, authentication/billing servers and network-management system. Samsung provided handsets, as well as V.4 technology for doubling voice capacity. Qualcomm provided handsets, as well as the MSM5000 chipset and system software.

After the first phase of testing, Sprint PCS brought in Lucent, Motorola and Nortel to conduct additional testing. So far, it's all pre-commercial products. Vendors are expected to deliver commercial hardware and software later this year. If all goes according to schedule, Sprint PCS will start rolling out 3G 1X later this summer and have nationwide coverage rolled out by June 2002.

Through the testing, Valente said Sprint PCS wanted to verify the three main benefits that it needs from 3G 1X: improvements in voice capacity, data rates and battery performance.

According to Valente, “The testing is coming out as expected.”

In the pre-commercial phase, voice capacity increased 1.8 to two times. The data rates reached peak performance of 144kb/s consistently, whether close to a cell site or far away.

As for battery performance, Sprint expected to reach a 50% improvement. However, the tests revealed 30% to 50% improvements.

“We just haven't had the devices to test en masse yet,” Valente said. “However, between now and 2002, there'll be more 1X devices to test the (battery) performance.”

This performance improvement will help when color screens begin populating the 1X landscape. The laws of physics predict that color screens will draw more battery power, but Valente hopes the improvements will offset any customer perceptions of drain.

Voice Capacity

The major limitation of lab tests is that they aren't commercial. But Sprint PCS has pushed the network hard in the pre-commercial phase. Among the many tests it has conducted, it has simulated multiple calls on the system and added interference to simulate what you would see as capacity increases.

So how far can you push a system? Valente said that, unfortunately, you can't simulate millions of calls or stress the system as much as you would like. He added, however, that there are other ways to stress it.

“Although we can't do capacity, we do lots of what we call destructive testing,” he said. “In the middle of running a series of test calls, we introduce an error into the system and see how it reacts and see if it's able to recover.”

To test the system from a capacity standpoint, Valente said the company has to rely on commercial field trials.

“We do testing in our integration center. Then we do a first-market application, where we take it out to a field location and run virtually the same set of tests we ran in the lab. The difference is you have commercial traffic on it, and you're really able to stress it out from a load perspective. Then we make sure it works well in the field trial. Once that's done, we roll it out nationwide.”

Were there any surprises? Valente explained that Sprint PCS and its vendors went through learning curves together and experienced the normal growing pains you would expect to see in pre-commercial testing.

“The good side of that is they got worked out,” he said. “It has caused us to find things we could work out sooner rather than later. You really want to make sure you have found the problems before it gets near a customer.”

Blink Speeds

Later this year, when Sprint PCS rolls out 1X in the initial markets, which the company hasn't yet released, it will offer data rates of 144kb/s. So what does Valente think is more important — the data rate or the performance?

“You have to be careful on the whole data rate because you don't want to overhype the capability,” he said. “When we've talked about the data speeds, we've always said ‘up to’ 144kb/s. When you're into 1X, say it's ‘up to’ 307kb/s; 1X-EV-DO gets you ‘up to’ 2.4Mb/s, then beyond that, 3Mb/s to 5Mb/s. Those are peak data rates.”

According to Valente, average data speeds will be more important to consumers.

“What we think that'll be and how we're designing our network is under a loaded condition to be in the 70kb/s range,” he said.

At 70kb/s, will consumers be able to see a difference or have the perception of it being slow or fast?

“At 20kb/s to 30kb/s, e-mail works extremely well. Beyond that, you aren't really noticing what we would call a blink-speed difference,” he said. “If you're faster than 30kb/s, based on the application, you aren't really going to notice any improvement beyond 30kb/s.”

Valente said the company is applying that same logic to all of the applications — e-mail, Web browsing, audio streaming and video streaming.

“We're trying to get to the application speed where, beyond a certain point, the user wouldn't have a perceptibly different experience.”

The New Call Model

Beyond data speeds, Valente has had his hands full trying to apply reality to a strictly theoretical model.

“In the voice-call model, it's well-known from historical trends how much traffic goes on during the busy hour, what percent of the total traffic occurs during the busy hour, average hold times, busy-hour call attempts,” he said. “Those are all things that all of us operators have a good handle on.”

However, when it comes to mobile wireless data, there's a whole new set of variables at play.

“We're trying to do our best to understand what we think will happen there, but until we are launched and running, it'll be just that,” he added.

Valente examined wired Internet usage to see how people use it in terms of average session length. The average wireline Internet session is about 30 minutes.

According to Valente, the activity factor is an important variable in the data call model.

“If you think about how you browse the Web, and you're clicking on pages and spending quite a bit of time just reading what has popped up in front of you, you're not actually sending and receiving data. What the activity factor gets to is just that: For a given session, how many minutes are consumed sending and receiving data.”

Sprint PCS is developing what it thinks the activity factor will be for all of its applications and segments of traffic. Valente sees three distinct segments, each dictating different activity factors: Web browsing from your handset; Web browsing from a laptop (connectivity) using a data card and wireless phone; and telemetry services.

“When we look at those sorts of things, connectivity is the one we think will consume the most amount of bandwidth,” Valente said. “We made projections about what percent of our total data traffic is going to be doing a lot of these different things and then tried to design our network around that.”

Added in with the activity factor is time of day. In the voice-call model, peak and non-peak hours reflect rush hour and windshield time. And looking at the wired Internet model, Valente found Tuesday nights, Friday nights, all day Saturday and Sunday are big wireline Internet sessions. He expects different key days of the week and different kinds of usage with wireless data.

“The good thing is that right now we aren't anticipating it necessarily coinciding with the voice busy hour, which I think is a good complement to the network.”

Spectrum Stretching

At Wireless 2001, Charles Levine, Sprint PCS president & COO, said the wireless company had enough spectrum to last for 10 years. How can he be so sure? What if other carriers dropped off the face of the earth and everyone was coming to Sprint PCS for service? Valente backs up his boss but provides a more convincing testament.

Besides Sprint's having 100% digital in the same frequency, Valente credits CDMA for its efficiency and ability to add incremental improvements.

“Most of our competitors are encumbered by analog and digital technology. Some of them have less efficient digital technology than CDMA. They have multiple frequencies. Those are all challenges that we don't have.”

In addition, Valente expects vocoder advancements, 1X and smart antennas to deliver additional increases to maximize its current spectrum.

“With EVRC, you get 40% to 60% improvement in capacity. You're able to effectively carry more voice traffic with the same quality of service over less bandwidth. We're already deploying that in our markets today.”

“With 1X, you get another (potential) doubling effect,” Valente said.

That doubling assumes that there's 100% penetration of 1X devices. If on average, customers keep their devices for about 18 months, the coupling effect could be imminent.

Valente also identified select-mode vocoders (SMV), which are similar to EVRC.

“In the next two years, you'll see SMV vocoders introduced into the CDMA world, which will improve capacity potentially another 30% by taking the vocoder rate down to around 5kb/s to 6kb/s. That will be another voice-capacity improver.” (See Figure 2.)

In the next two to three years, he also sees smart antennas providing two to three times the capacity that is available today.

“All of these are additive,” he said. When you add all of these other capacity enhancements, you can offer improvements 20 times TDMA and GSM and 35 to 40 times analog capacity, Valente said.

With this type of capacity increase, Sprint PCS is looking to invest roughly $2 billion in its 4-stage upgrade.

“That would be getting us through 1X-EV-DV in 2003,” Valente confirmed. “That's probably about a 2- to 3-year forecast in terms of spending.”

Valente thinks it'll cost roughly $800 million to roll out the first stage later this year.

Invariably Variable

For someone who faces so many variables in the face of launching 3G services, Valente ironically seems quite calm. So what keeps him up at night? Without missing a beat, he said his children do, especially a daughter who was born during Wireless 2001.

Turning serious, he keys on making sure the vendor partners meet their commitments and schedules.

“It's a painstaking process of continual review of key milestones that are going to get you to the endpoint,” he said.

Perhaps the continuous review is what helps in a world so filled with variables. But Valente is philosophical about making the unknown known.

“We just need to make sure that to the extent problems come up, we're able to find them early and get a game plan in place to solve them.” <<

>> Sprint PCS 3G CDMA 2000 Migration and Launch (Webcast)

November 2001 at at the Soundview Technology Conference

Original obsolete link here:

vcall.com

"Sprint will be launching phase 0 (zero) CDMA2000. The CDMA2000 Release A standard should publish soon. Release A will take peak data rates from 144 kbps to 288 and average rates from 50-70 kbps on PCS with phase 0, to 100 kbps. This capability requires cdma2000 Release A. Sprint expects to make Release A capabilities available by mid-year 2003. PCS will probably skip 1xEV-DO, and instead migrate to 1xEV-DO by mid-year 2004 with peak rates in the 3 to 5 kbps range." - Oliver Valente, Sprint PCS CTO - <<

>> Building Up: Sprint PCS

Wireless telephones are poised to get a lot more powerful, with diverse new offerings that alter the way we communicate. Sprint PCS intends in a few months to become the first wireless carrier to offer so-called 3G or third-generation technology.

Sprint's chairman, William Esrey, likened the advent of the new service “to television's move from black and white to color broadcasting.”

The commitment to being a technology leader, many believe, has enabled Sprint PCS to reach $10 billion in annualized revenues in five years — faster than any company — including Microsoft, which took 15 years to reach that milestone. Sprint PCS recently reported $2.9 billion in net operating revenues in the first quarter, up 40 percent from one year earlier.

To better understand the technological challenges Sprint PCS faces, we recently interviewed Oliver M. Valente, the company's chief technology officer. His comments, edited for style and length follow.

UB: What are the responsibilities of Sprint PCS's chief technology officer?

VALENTE: Well, what we are responsible for is creating a technology roadmap for Sprint PCS, managing our R&D, looking at industry standards and trying to drive industry standards in a way that will benefit the industry as well as Sprint PCS. And before anything ever touches customers' hands it's been through an extensive set of tests. There's a huge focus on increasing the capacity of our systems and the cost efficiency of our systems. We're trying to think ahead of the marketplace where we think the industry is going.

UB: Are you looking beyond 3G?

VALENTE: 3G wireless is only one of the focus areas. It's a huge one for us right now that we've been looking at for three years. A lot of what Sprint PCS had advocated has ended up being true. We felt that competing technologies were going to get delayed and were going to be causing operators to need to buy spectrum. Both of those things happened and so many operators ended up spending billions of dollars only to find the technology was not there when they needed it.

UB: How is the wireless industry managing costs?

VALENTE: We'll be able to have a lower cost structure and be able to manage the same number of customers and really manage our growth in a more cost efficient way. It's all about packetizing and the way in which you transport your traffic.

UB: What new applications are coming?

VALENTE: Today, the laptop is the main device that takes advantage of speeds of more than 100 kilobytes per second. Over the next 18 months we want to make sure that come 2004 — when we'll have that ability to deliver data at 200 to 300 kilobits per second on average — there are devices there to take advantage of that.

UB: What kind of consumer uses do you see?

VALENTE: The killer applications we see this year with the launch of higher-speed wireless data, which is what 3G is, are more robust versions of what we have already — messaging, e-mail, web browsing, interactive or downloadable games. Business people will have the ability to access corporate information, e-mail, contact lists and calendars at a higher speed. You are going to see devices getting better color screens and a desktop experience on a PDA or phone-type device.

UB: Are you talking with manufacturers in Korea, Japan and elsewhere about developing products?

VALENTE: Absolutely. Sanyo, Samsung, Kyocera and LG — those are just some of the vendors that we are working with from a device standpoint.

UB: Who leads the charge in innovation — product vendors or wireless operators?

VALENTE: It will continue to be a combination of operators and equipment suppliers that will come up with innovative things.

UB: Are you testing any new devices right now?

VALENTE: Yes.

UB: What will 3G service cost?

VALENTE: We have not released what our pricing plans are going to be. We're going to have the ability to bill by monthly recurring charge and bill by the kilobyte.

UB: Do you see 3G wireless becoming a differentiator between wireless companies?

VALENTE: The differentiation will be there day one. Sprint will be able to offer better devices, a larger selection of devices, better capabilities and faster speeds than a number of our competitors who are using non-CDMA-based technologies. We are going to be able to do all those things faster and more economically than our competitors.

UB: How long-term is your planning horizon?

VALENTE: We have occasional discussions about 10 years out but that's unrealistic for practical planning purposes. A more serious focus is probably on a 4-year time frame.

UB: As chief technology officer, how many people do you have working with you and what's your budget?

VALENTE: Several hundred people.

UB: And your spending levels for research and development?

VALENTE: In R&D, I would say we probably have not reached our peak within the wireless industry compared to what other industries spend. We are now seven years old essentially, and the first five years were spent with a real SWAT team approach to building out the company and the network and building the customer base. In the last 18 months we've sort of hit a more mature cycle of our business. What we spend on R&D to maintain product leadership will hopefully increase beyond what it has been.

UB: What has Sprint PCS spent to prepare for 3G?

VALENTE: Sprint has invested in the ballpark of $800 million over 18 months to upgrade the network nationwide to get every single cell site in our network 3G-enabled. And that's a fraction of what competitors have to spend because Sprint designed its network with 3G in mind.

UB: What future capital expenditures are planned?

VALENTE: We're looking for a good return on investment before we take a huge step forward. We have a clear-cut migration path that takes us from what essentially will be the ability to offer peak speeds in the 140-kilobits per second range. I think if we get that out we may have an opportunity to capitalize on that for 18 to 24 months before we need to take our next big step in technology, at which time we think we can take that capability to new peak speeds of a megabit per second.

One of the main benefits of that $800 million investment is that — unlike other competing technologies — we will get a 70 percent increase in the capacity of our network that will be applied to voice and data services.

UB: Will that help with problems like dropped calls?

VALENTE: In 2001, we saw our average minutes of use per subscriber increase 25 percent. In that same period, we've seen blocked calls and dropped calls come down into the low single- digit percent range. We've managed the performance of our network well.

UB: What sets Sprint PCS apart from competitors?

VALENTE: Right now we are the largest wireless web provider in the country. At the end of 2001 we reported we had more than 2 million users of the service. We're rolling out a wireless service that will have better capabilities, better device selection and better applications. That will allow us to continue to lead the industry. <<

>> Sprint's 1X View

Barb Lee
Wireless Review
Jan 15, 2001

Sprint PCS is confident of both its network and technology as it gets ready to offer 1X services.

As Sprint PCS moves toward offering next-generation services, it cites its CDMA all-PCS network as a major advantage in the race to 3G.

"If history provides any insight into the future, Sprint PCS and its single-band, all-digital network will be as adaptable to 3G migration as it has been in offering first services to its nationwide market," said Oliver Valente, Sprint PCS CTO. "Sprint PCS will be able to deploy the technology ubiquitously by simply plugging in new 3G channel cards to its existing base stations and adding some new software. We anticipate our roll-out to be accomplished with relative ease and with less expense than any other of the competing and less-3G-friendly technologies used by competing national carriers."

Unlike some consolidated or merged networks that operate at multiple frequency bands and on multiple technology platforms, the Sprint PCS network doesn't need to rely on multiple back-office support systems. In fact, some carriers require more than a dozen different billing systems because of disparate overlay networks and mergers between operators with different back-office systems.

Another advantage Sprint PCS is touting: Except in a few select markets, it has enough available spectrum to meet expected 3G demands.

Sprint PCS will begin offering what it has dubbed "3G 1X" later this year. Sprint's 3G 1X - more commonly known as cdma2000 1XRTT, or cdma2000 1X for short - is part of the IS-2000 family of standards that has been accepted by ITU, the worldwide standards body dictating and legitimizing the specifications of 3G. Sprint's 3G 1X offering will begin commercial deployment in the second half of 2001, with complete wide-scale deployment slated for the end of June 2002.

The 1X-capable handsets that will operate on existing 2G networks will be available at the earliest in 3Q01. Several carriers already have committed to make handsets using 3G chipsets. Sprint PCS anticipates more vendors joining before the handsets are available for widespread distribution. Many experts believe that the sooner the vendors begin seeding the market with the 1X handsets, the better for wireless carriers in terms of capacity once 3G 1X infrastructure is deployed.

Sprint PCS currently is testing 3G 1X technology with major network carriers such as Lucent, Motorola, Nortel and Samsung. In March 2000, it made its first successful call in North America, with Samsung and Qualcomm, in the Sprint PCS Technology Integration Center. Following another year of field trials, Sprint's 3G 1X technology is expected to be implemented in about 4,000 cities on the nationwide network.

Costs Readily Recovered The total cost for Sprint PCS' national 3G roll-out is estimated at a comparatively low $700 million to $800 million, an investment that should be regained readily in terms of greater consumer usage and extended business applications, Valente said. Through the added voice capacity - up to double the 2G capacity - as well as the higher-data-speed services, the 3G network is one that "we know we can sell and make a return on our investment," he said.

"Over the next two to three years, the 3G speeds will rapidly accelerate into multimegabit-per-second speeds that will accelerate all types of applications and services in the mobile wireless environment," Valente continued. "Consumers will have more of a desktop experience in the handset. Once the high speeds are available, the playing field really opens up."

Not only will consumers be able to browse the Web at far faster rates, but Valente projects that by the first half of 2002, handsets will evolve that will include more color screens, video transfers, photographs, music downloads and a whole new set of service capabilities.

"All in all, the 3G handset will be a very cool end-user device," he said.

Who Will Use It? But is there realistically a market for this latest innovation in data technology? Warren Wilson, Summit Strategies senior analyst, said that high-speed data and data enhancements alone may not win the U.S. consumer. According to Wilson, people in the U.S. telecommunications industry tend to look to Europe and Asia for indications on how the U.S. market might develop.

In those markets, wireless data has been - to a large extent - a consumer-driven service. Therefore, early speculation in the United States was that individual consumers here also would drive the wireless-data market. This may not hold true, however, because of major differences in what Eastern markets are able to offer the end user compared to what is available in the United States, Wilson said.

"In Europe and Asia, where PC ownership and Internet access are less common than in the United States, wireless handsets have given many people their first taste of e-mail and the Internet," he said. "They're probably more accepting of the phones' tiny screens and keypads than U.S. consumers, who are used to doing e-mail and Web surfing with large PC monitors and full keyboards. So consumer-focused wireless-data services probably won't see the same adoption rates in the United States as they have elsewhere."

"On the other hand, many U.S. businesses have already Web-enabled key applications; for them, wireless is a logical next step - though it's not necessarily easy or inexpensive," Wilson said. "So we expect that in the United States, wireless data will be more business-driven than consumer-driven."

Technology Advantage Sprint does seem confident that its technology offers an advantage in the 3G race over the TDMA and GSM carriers that are moving toward a WCDMA 3G solution reached via GPRS and EDGE.

"In terms of competitive advantages, the Sprint PCS 3G technology will be more robust, faster, and more seamlessly deployed on our network," Valente said. "We are not particularly concerned about GPRS solutions. Although they do increase data throughput, they don't enhance voice capacity, and the battery performance is greatly depleted by the data drain. On the contrary, the three major benefits of the Sprint PCS 3G migration are: up to double the voice capacity of the network; increased data speeds 10-fold; and increased battery-performance life in standby mode up to 50%."

Looking ahead, Sprint PCS expects to roll out 1XEV DO to its network in early 2003.

One thing is sure: Sprint PCS and other carriers are betting that the market will be ready for 3G services and the speeds it will offer.

"Wireless is the newest frontier and American businesses, particularly, are looking to make a leap from wired Internet to wireless Internet," Wilson said. "The stage is set for that leap." <<

March 16, 2001

Sprint president Charles E. Levine said Sprint's CDMA-based PCS network will give it an advantage over competitors in 3G network migration.

In an effort to get a jump on 3G wireless in the United States, Sprint PCS (NYSE: PCS) Thursday said it plans to start rolling out next-generation technology to its customers later this year. The announcement follows a report published Thursday by the Washington Post that BellSouth is pursuing the acquisition of Sprint.

First in Line

Sprint president Charles E. Levine will unveil the company's strategy for introducing 3G technology into the Sprint PCS network on March 20th at the CTIA Wireless 2001 conference in Las Vegas, Nevada, the company said. Demonstrations of applications running on the 3G1x platform, Sprint's first phase of 3G, also will take place at the Lucent booth at the CTIA exhibit hall.

Sprint PCS, the United States' largest all-digital, all-PCS wireless network, said it will work with network infrastructure providers Lucent Technologies (NYSE: LU), Motorola Cellular Infrastructure Group (CIG), Nortel Networks (NYSE: NT) and Qualcomm Inc (Nasdaq: QCOM) to offer the first 3G wireless service in the United States.

The company serves more than 23 million customers in 4,000 U.S. cities and communities, and reported US$23 billion in annual revenues.

Banking on CDMA

Sprint is banking on the development and deployment of its PCS network, which is based on CDMA (code division multiple access) technology, to give it an advantage over competitors in 3G network migration, Levine said.

Sprint's 3G1x technology will offer three major benefits to customers, according to the company -- up to twice as much voice capacity, a tenfold increase in data speeds from 14.4 kilobits per second (kbps) to 144 kbps, and a 50 percent increase in handset standby mode battery performance.

3G technology promises to deliver advanced services such as audio and video streaming and a variety of e-commerce applications when it is introduced.

"While the rollout to the next generation of wireless services will be a gradual evolution, Sprint PCS has a network that was built with 3G in mind and an aggressive migration path," said Oliver Valente, chief technology officer for Sprint PCS.

"And, based on recent announcements regarding delays and costs associated with transitions to W-CDMA, we expect to have a significant timing advantage, entering the market far earlier than most competitors," Valente added. <<

Super speeds to deliver streaming video and audio on mobile phone applications

Sprint (NYSE: FON/PCS) and Lucent Technologies (NYSE: LU) have completed the fastest-ever third-generation (3G) over-the-air data call for a U.S. mobile wireless carrier, at speeds of up to 2.4 megabits per second (mbps). Within the next two years, these high-speed data rates promise to alter the way people traditionally use wireless services and will enable Sprint PCS customers to take advantage of 3G advanced mobile phone applications such as streaming video and audio.

The successful call was conducted on April 5, 2001, at Sprint's test site in Lenexa, Kan., using a new technology protocol called CDMA2000™ 1xEV-DO (1x Evolution-Data Only). This 3G Code Division Multiple Access (CDMA) technology makes it possible to transmit data up to 165 times faster than what now is available on wireless voice and data networks. With these speeds available on Sprint's network, consumers will be able to download music to their phones directly from the Internet or send pictures from remote locations such as the beach or the mountains. Business customers will be able to open complex e-mail attachments using wireless modems in their laptops without seeking a payphone or using expensive hotel connections.

Sprint, which is testing the 1xEV-DO technology through June, will test increased data throughput and capacity available with 1xEV-DO technology and also various applications such as web browsing, file transfer and streaming video and audio.

Lucent's commercial Flexent™ CDMA base stations and QUALCOMM's 1xEV-DO test equipment is being used in the trial. Commercial availability of Lucent's CDMA2000 1xEV-DO base stations is expected in 2002. The technology is expected to be deployed into the Sprint PCS wireless network by 2003.

"Our successful data call using 1xEV-DO demonstrates that Sprint PCS is on time and on target in delivering on the first steps to bring high speed mobile Internet access to our customers, allowing them to experience new and richer applications," said Oliver Valente, chief technology officer for Sprint PCS.

"This milestone data call further demonstrates Sprint's industry-leading position in 3G. From a wireless spectrum perspective, Sprint is equipped with enough spectrum nationwide for the next 10 years and will introduce high-speed packet data (3G1x) nationwide in 2002. Using our existing infrastructure to upgrade the Sprint PCS network to 3G by simply changing out channel cards in our base stations will ensure a timely, smooth and cost effective migration. Plus, it gives us the ability to be first to market with many new sophisticated mobile services," Valente said.

The Lucent equipment that achieved the higher data transmission rates with 1xEV-DO promises to provide a cost-effective means to meet the demand for high-speed mobile Internet access. This is accomplished through an evolution to an all-Internet Protocol (IP) core network with Lucent's Flexent Mobility Server and a simple circuit card and software upgrade to existing Lucent base stations.

"Our solution will help mobile operators efficiently deliver high-speed mobile Internet services to their customers," said Mary Chan, vice president of development for Lucent's Wireless Networks Group. "We're committed to delivering this technology to meet the needs of our customers as they evolve to higher-speed 3G technologies."

Sprint's aggressive 3G deployment for CDMA2000, also known as 3G1x, will result in the eventual doubling of the voice capacity of the Sprint PCS network; up to a tenfold increase in data speeds from 14.4 kbps to speeds of up to 144 kbps; and increased battery life for handsets in standby mode by approximately 50 percent. By early 2003, Sprint will move to the second of its four-stage migration path with speeds of up to 307 kbps. Later in 2003, peak speeds will reach those replicated in the Sprint-Lucent data call -- up to 2.4 mbps -- with 3G1xEV-Data Only (DO). In 2004, speeds will reach 3 mbps to 5 mbps with 3G1xEV-Data and Voice (DV).

Based on High Data Rate technology initially pioneered by QUALCOMM, CDMA2000 1xEV-DO complements the existing CDMA2000 3G1x. Last year, Lucent Technologies and Sprint PCS conducted field trials of 3G1x demonstrating peak data transmission rates of 144 kbps. Sprint will deploy CDMA2000 3G1x technology later this year. <<

>> Sprint Launches PCS Vision, A 3G High-Speed Wireless Service

After years of planning and $1.4 billion in development, Sprint Corp. on Thursday launched its next-generation high-speed wireless phone service across the country.

Sprint is hoping the new service, called PCS Vision, will spark new sales and reverse a slump that led to the company last month losing its leadership position in wireless industry growth.

"This re-establishes our competitive advantage in the marketplace," said Charles E. Levine, president of Sprint's PCS division. "Sprint is once again leading the industry."

Sprint, which has its headquarters in Overland Park, had been the fastest-growing wireless company for almost four years, but it lost that title to Verizon Wireless in July.

The high-speed service, sometimes referred to as 3G, allows wireless customers to use their phones to connect to the Internet at speeds comparable to -- and often faster than -- connection speeds offered by traditional dial-up Internet services.

Levine called PCS Vision the most significant launch for Sprint since the company began offering wireless phone service in 1997. The company was careful not to draw any comparisons with its high-speed, landline-based ION bundled services project, which was scrapped last year as the company wrote off a $2 billion-plus investment.

Sprint's FON tracking stock closed Thursday at $9.90, up 33 cents. The company's PCS tracking stock closed the day at $4.11, up 27 cents.

The company will begin advertising and selling PCS Vision on Sunday, aiming at business customers and consumers.

Sprint, the nation's fourth-largest wireless service, with 17 million customers, is planning to leverage its longstanding "clarity" message by describing PCS Vision as "clarity our customers will see as well as hear," Levine said.

The first company to unveil plans for third-generation wireless service, Sprint is the last of the large wireless carriers to offer advanced services in the Kansas City area.

Verizon Wireless, which analysts believe will be Sprint's strongest challenger in the data market, launched its version of 3G in Kansas City in May. The service was available in some markets as early as January.

Verizon, which has 30.3 million customers, expects to offer the service throughout its network by the middle of next year, said Cheryl Bini, a company spokeswoman.

Sprint is rolling out nationally, something executives have consistently promoted as a major advantage. Business customers, in particular, want to know that service is available wherever they go, Levine said.

While Sprint did much of its conversion to 3G by simply swapping out software at network base stations, the project still was a huge undertaking.

"I don't want to understate the challenge of pulling something like this off," said Paul Reddick, vice president for business development. "It's really a lot of choreography."

The network infrastructure, back-office billing functions, applications to run on the network, and the devices themselves all had to be pulled together.

While some analysts expected the service to be launched earlier in the summer, company officials maintained that the deadline always was the end of the summer.

Launching 3G now gets the new devices in stores in plenty of time for the industry's biggest selling period, the fourth quarter. Levine said the company expects to see improved customer growth in the last three months of the year as a result of the launch.

Sprint has provided data service, branded the Wireless Web, since September 1999. But that service, with 2.5 million users, is sluggish compared with PCS Vision.

The new 3G service, as well as services planned by all the wireless companies, relies on packet switching technology, which breaks voice and data calls into digital packets before they are sent. Currently, most wireless services rely on traditional circuit switching, which is not as efficient.

Packet switching requires less bandwidth, allowing the companies to add customers to existing networks without causing congestion. In addition, 3G allows the companies to add a variety of other services.

However, technology aside, Sprint thinks consumers will be lured by snazzy phones with color screens that include gadgets like digital cameras. The company also is promoting instant messaging, downloadable games, screen savers and ring tones.

"These are becoming mini-PCs in a sense," Reddick said.

Levine, who was in New York on Thursday promoting the service to national media outlets, said business customers will buy the service for fast mobile access to corporate e-mail, calendars and contact lists.

And in the process, Levine said, Sprint will see increased profits and more customers. He thinks the new service will help Sprint maintain or even increase the $60-plus that average customers spend for PCS service each month, even while the cost of voice service drops because of competition.

Current Sprint PCS customers won't see much of a change unless they decide to upgrade to the new service.

Sprint will launch the service with a wireless card for laptop computers and four phones, including a new Samsung phone that can be linked to a small digital camera to send photos by e-mail. PCS Vision customers will pay for traditional phone calls by the minute, but the company will charge customers for data by the megabyte, based on how much information is sent across the network.

Sprint PCS customers who have used the Wireless Web pay for data service by the minute.

Levine said customers might not understand the new "per megabyte" pricing plan, so Sprint is quantifying it based on the number of e-mails, instant messages or pictures it will hold.

For example, with two megabytes, a customer could send 150 e-mails, 100 instant messages and four pictures; view 100 Web pages; and store four ringer tones, four screen savers and four games.

In general, pricing plans range from about $50 a month for 4,000 minutes of talk time and two megabytes of downloads, to $120 for 10,000 minutes and eight megabytes of downloads. A straight Internet access plan geared for businesses ranges from $40 for 20 megabytes to $80 for 70 megabytes.

Suzzana Ellyn, a wireless data analyst for research firm ARS Inc., said Sprint's pricing plan undercuts the plans offered by other carriers.

Sprint's pricing strategy also is designed to help customers gain an understanding of wireless data. For example, the company is giving away three months of PCS Vision to lure customers to the service.

"People don't know what a kilobyte looks, feels or tastes like," said Charles Golvin, an analyst with Forrester Research. If they get the chance to try the data services, they may be more comfortable paying for them in the future, he said.

It remains to be seen whether customers will want to buy. Outside of a few select groups -- gadget lovers, business travelers and, perhaps, gamers -- many analysts wonder whether people will be willing to plunk down lots more for data.

"This is not for people on a budget," said Alan Reiter, an analyst with Wireless Internet & Mobile Computing outside Washington. "...This is not a low-cost option, nor is this a substitute for any landline Internet connection."

Most analysts agree that getting customers to buy 3G will require a good bit of education.

So far, Sprint's competitors don't seem to be doing that very well, said Andrew Seybold, a wireless analyst. He was disappointed with what he saw after visiting Verizon Wireless and Cingular retail stores recently.

"Nobody in those stores knows how to sell data," he said. "The challenge for Sprint is educating people in their stores. That's the first place people have to be exposed to data services, and if they don't get it right there, it's going to hurt them."

And Sprint may have to play down its own hype to succeed. Consumers who have been hearing about 3G for years may be underwhelmed when they finally see what Sprint is offering.

"The whole wireless industry has whipped up a frenzy about 3G," said Jeff Kagan, an industry analyst. "Most customers are expecting a lot."

But while Sprint's new service does open a new chapter in wireless, Kagan said, it won't be the futuristic service some people are hoping for. And that could backfire, he said.

"You don't want to overpromise and underdeliver, because then you have to explain why," Kagan said.

But Sprint is coming to market with a wider array of phones and services than its competitors, Reiter said.

"I think in some ways Sprint is going to give Verizon and AT&T a very good run for their money," Reiter said. "Right out of the box, Sprint is introducing a nice selection of phones and two modems for business users."

The product choices may be an advantage winning some customers, especially gadget lovers and young customers who care about the aesthetics of a phone. But Sprint's coverage isn't as strong as its competitors, Reiter said.

"If you want cool phones, you go to Sprint," he said. "If you want the best nationwide voice coverage, you look at Verizon and AT&T." <<
