Wireless carriers ponder technology flip
BellSouth International, Nextel examine CDMA

As wireless carriers consider the economics of next generation services, the industry may stray from traditional migration plans when it comes to deploying high-speed data networks.

Already, BellSouth International is making the decision to overlay CDMA-based 1XRTT technology over its existing TDMA networks in Latin America. And nationwide U.S. operator Nextel, which uses GSM derivative iDEN technology, also may change technology for the next generation. The carrier has told Wall Street analysts that it is studying 1X technology in addition to enhanced data rates for GSM evolution (EDGE) technology. Nextel did not return phone calls seeking comment.

"BellSouth is very heavily leaning toward CDMA as an overlay eventually in all of its markets over the course of a three-year period," said a source familiar with BellSouth’s plans.

Migration to 1X technology could be common as carriers review the economics of moving toward a data market that is unproven at this point, say industry observers. 1X technology adds voice capacity and high data speeds within today’s spectrum constraints. Wideband CDMA (W-CDMA) networks require carriers to carve out large chunks of their existing spectrum—a negative because it’s unclear how much spectrum will be available to U.S. operators.

TDMA and GSM carriers have a common high-speed data migration path called EDGE technology, which will require core network changes for TDMA operators to reach high data speeds with no capacity enhancements. Nextel previously has aligned itself with the GSM community.

"There’s a concern for spectrum, and 1X is more spectrally efficient than EDGE or W-CDMA," said Neal Campbell, director of CDMA product operations for Motorola. "There is a lot of discussions going on. People are considering CDMA…. Operators are doing the cost/benefit analysis and realizing they still have to make significant upgrades to go to EDGE or UMTS."

Carriers deploying 1X technology have more high-speed data options because they can dedicate a 1.25 MHz channel to reach speeds of 2 Mb/s. The CDMA community also is trying to standardize higher-speed technologies that would provide speeds of up to 5 Mb/s.

"In the long term, it’s a great upgrade path," said Dave Berndt, director of wireless mobile technologies for The Yankee Group. "With the capacity factor, carriers don’t have to go to [wideband systems]."

Timing is another factor. EDGE technology won’t become commercially ready until late 2002. Korean CDMA operator SK Telecom already launched the service, while U.S. carriers have deployment plans for mid-2001. Sources close to BellSouth say the carrier wants to hit the market with data before its TDMA competitors in Latin America.

Many technology analysts say 1X could become a de facto standard for operators constrained by spectrum. For example, all three of Korea’s CDMA operators deploy 1X technology within their existing systems but have stated their intention to deploy W-CDMA technology within new 3G spectrum.

Nextel also is likely to deploy W-CDMA technology in new bands if it gains enough spectrum in future auctions, analysts say.

"Nextel wants to talk to everyone because it realizes iDEN is a dead end," said Matthew Hoffman, wireless communication equipment analyst for Wit SoundView. "It’s clear they need to explore other options, and CDMA is a viable strategy in terms of what you can do with spectrum. Nextel would have the rip out infrastructure either way."

Switching to 1X technology may not be any more expensive than migrating to EDGE technology. Seventy percent of capital expenditures lie within the base transceiver stations (BTSs), meaning carriers would have to make significant changes regardless of technology, Campbell said.

It’s also unclear whether EDGE technology will gain the economies of scale sought by the TDMA community when it aligned itself with the GSM world. European operators have yet to announce their intentions to deploy it. Some analysts say European carriers may skip the technology altogether and choose to spend their money on W-CDMA.

Any of you guys listen to this?

I am listening to it, Nok was asked directly about q license for 3G and gave a very confusing answer, any of you want to provide your interpretation?

Pretty worthless call.

The way I see it the mobile high speed (>64k) market is mostly fixed or at least stationary...The way I see it the market for high speed truely mobile connections is very small, journalists, police, etc, and not a question of beeing the size of a handset in a pocket...GSM-GPRS with good coverage and higher burst rates takes care of most of this for a long time to come.

I have to disagree. There's a few major, potentially mass-market, bandwidth-intensive applications that are possible for small, sub-150 gram smart phones. Right off the top of my head, on-demand MP3 streaming, streaming video playback, videoconferencing support (I know, this one's a while off), and online video game playing come to mind. These obviously aren't applications which, if implemented correctly (considering how stupid telecom operators in general can be with regards to service deployments, that's a big "if"), will see their popularity relegated to small, vertical niche markets.

Although I don't think that 2 mbps connections are needed for such apps, especially when taking into account the relatively small screen sizes of phones for the video-related ones, 100-200 kbps, which should eventually be possible with a large % of major 3G rollouts, will most likely be required; and even if other technologies such as GPRS, EDGE, and a packet-switched version of IS95/B were somehow able to provide the necessary data rates, cost also has to be factored into the equation. Obviously, even when taking into account the use of a packet-switched architecture, a high-quality MP3 file or video clip that's streamed to a user is going to take up far more capacity than a phone call ever will. To convince consumers to use such services, per-minute pricing will have to be fairly close to what's charged for telephony. For example, I doubt that too many people will be willing to pay 40 cents/minute to listen to an MP3 clip. On the other hand, 10 cents/minute may be tolerable for some people. I doubt that this possible with non-3G technologies.

On another note, the fact that many of the most popular 3G applications may turn out to be consumer-related could potentially alter the manner in which deployments take place. As we all know, it's inevitable that, given the costs, the first 3G rollouts will take place in major metro areas with high population densities and ARPUs. However, where the rollouts go from there could depend on which serices generate demand, and what types of people the demand comes from. If it's found that most 3G subscribers tend to be business users who use the technology mostly for work-related purposes such as laptop internet connections and client/server business apps, then operators will most likely be very slow to expand deployment beyond major cities, given how these cities will always be the ones that act as major business hubs. On the other hand, if it's found that 3G services are devoured to an equal, if not greater extent (as I expect), by regular consumers who use 3G handsets for MP3 streaming, game playing, streaming video playback, etc., then carriers will have a major economic incentive to start making major deployments within smaller towns and suburban neighborhoods, an incentive that's strengthened in certain countries by the huge fees that they may have paid for their 3G spectrum licenses.

Of course, it could be argued that even if such services become popular among consumers, and even if they're cheap enough that many individuals feel comfortable with using them frequently, 3G handsets with support for such features could be so expensive that most consumers won't be able to afford them. However, it should also be noted that since these handsets allow carriers to offer a more diverse array of value-added services to their subscribers, they'll have a major incentive to significantly increase the extent to which they subsidize the cost of buying such a handset. Likewise, carriers could also attempt to entice users by means of subsidizing the cost of new, value-added services that they offer, provided that a given subscriber buys a handset that supports the service. Sprint, which tends not to subsidize handsets a whole lot, has recently done this, offering a music management service for free for one year to those who buy Samsung's new MP3 phone. Either way, the relatively higher wholesale costs that 3G handsets will have may not prove to be as great a barrier to widespread consumer acceptance over the long-term as some might expect.
