3G can survive says Tantivy
3G is down but not dead says Randy Roberson, CEO with Tantivy. He argues that price and usage will determine the success of3G. Robertson says flat rate fees are now possible thanks to overlay networks deliver a quicker ROI (return on investment) and fewer physical roll-outs. Most controversially he says that xDSL and cable broadband still have problems while 3G can be more reliable and deliver at a lower cost. Consumers are the key, requiring 3G in both the home and in the mobile office. Naturally Tantivy's own technology, I-CDMA (Internet-CDMA), provides the answers by making wireless applications easier and more robust. I-CDMA is an overlay technology for CDMA based networks which enables flat rate billing for carriers and ISPs. Which explains why Tantivy believes the future of 3G is being demonstrated in Korea not the Isle of Man.

and
Melbourne, Fla.,—Nov. 1, 2001— Tantivy Communications, Inc., a provider of portable wireless broadband solutions, today announced that its patented I-CDMA™ (Internet-Code Division Multiple Access) technology has been successfully tested and proven over-the-air in both rural suburban and dense urban environments in South Korea. Earlier this year, the company had announced its field trial agreement with Shinsegi Telecom, Inc., a South Korean provider of wireless CDMA communications services and Hanwha Corp. Telecommunication Division, a South Korean manufacturer of wireless communications infrastructure equipment and subscriber devices. Recently, SK Telecom and SK Shinsegi Telecom announced their agreement to a merger. Scheduled for completion in January, the new company will be the largest CDMA service provider in the world.
The Field Trial agreement was comprised of two separate field trials designed to test I-CDMA at market locations that emulate typical user experiences. The first trial was performed in a suburban area in Wonju, South Korea, during July and August 2001, and the second trial was conducted in a dense urban area in the Jung-gu district in downtown Seoul, South Korea, during September and October 2001. Testing for both trials was defined to prove the performance of I-CDMA technology capabilities in three major areas: speed of data throughput rates, system capacity, and coverage.
The rural suburban testing in Wonju achieved results that met and in some cases, surpassed the very aggressively targeted performance expectations. First generation I-CDMA technology employed in this trial achieved high-speed forward and unheard of reverse link data rates at distances exceeding 6 kilometers from the cell site. In data collections made throughout the cell coverage area, the average forward link data rates were 263 Kbps per user and the average reverse link data rates were 176 Kbps per user. Ten subscriber devices or TANLink Access Units (TAUs) were used to simulate typical activities of both consumers and business professionals while they do Internet surfing and implement File Transfer Programs (FTPs) in an “always on” environment.
The dense urban testing, performed in downtown Seoul, South Korea, also achieved results that fully met and in some cases, surpassed targeted performance expectations. This field trial achieved high-speed forward and reverse link data rates at distances exceeding 2.3 kilometers from the cell site. In data collections made throughout the cell coverage area, the average forward link data rates were 288 Kbps per user and the average reverse link data rates were 179 Kbps per user. All testing was performed using two Base Stations (BTSs) with sector antennas and 10 TAUs. The testing proved I-CDMA meets and exceeds the aggressive performance claims made using a Frequency Allocation (FA) that was between two adjacent active voice FAs. Additionally, the use of Tantivy’s proprietary intelligent array antenna in the TAU subscriber devices enabled the I-CDMA system to achieve impressive near symmetrical results in the dense RF environment of downtown Seoul.
"There is little doubt that users value reliable wireless connectivity that provides the speeds required to effectively access multimedia content and mission-critical applications," said Iain Gillott, principal and founder of iGillottResearch, a market strategy consultancy focused on the wireless and mobile industry. "The trick is providing a level of reliability in today's increasingly RF-unfriendly metropolitan areas. Seoul is known to be a particularly harsh RF environment - if you can make it there, as Tantivy’s I-CDMA technology has proven it can, you can make it just about anywhere!".
Later this month, Tantivy and Hanwha will be staging demonstrations of the I-CDMA technology in downtown Seoul. These demonstrations will include two way, real-time wireless video conferencing, FTP sessions, online gaming, and other typical broadband Internet user applications.
“We are pleased to be leveraging our existing CDMA 800 MHz spectrum to test this advanced wireless broadband technology in our local Korean markets,” stated Sang Ghil Lee, vice president of SK Shinsegi. “This trial marks an important step toward meeting pent up subscriber demand for 3G high-speed data services.”
“With the Seoul field trial testing now completed, Tantivy has demonstrated I-CDMA portable broadband capability in the harshest of wireless environments,” commented Tom Gorsuch, Tantivy’s vice president of product development. “I-CDMA’s performance rates make it the ideal wireless broadband solution for laptop users wanting wireless access to all the rich content of the Internet, and it also gives users the ability to send and receive large emails and file attachments rather than just manipulating reformatted web content-which is prevalent with other proposed voice-centric 3G solutions.”
I-CDMA is the only 3G Internet-centric technology available today to enable portable, end-to-end, wireless broadband Internet access. I-CDMA technology wirelessly replicates the desktop Internet experience, giving consumers anywhere, always-on Internet access. This technology provides peak data throughput of 1.9 Mbps, supporting per user access speeds of 365 Kbps for downloading and 222 Kbps for uploading data-an experience comparable to today’s alternative high-speed wire line solutions. I-CDMA technology can support 1,000 users per base station-which is several times more than the user capacity of 2.5G network technologies.
“We believe that superior performance for both forward and reverse data links, as well as intelligent antenna technology employed within subscriber devices will prove to be critical to the success of all 3G networks,” stated Tantivy President and CEO Randy Roberson. “With the successful completion of these trials, we anticipate I-CDMA technology will emerge as the premier solution for the multitude of devices that will benefit from always on, anywhere, anytime, portable Internet Access, such as the growing notebook computer user segment.”
Under terms of the field trial agreement, Shinsegi was to test and evaluate equipment provided by the Tantivy-Hanwha team, in addition to the associated software and documentation licensed by Tantivy to Hanwha. Three basic system components have been deployed in the field trials including: subscriber units, leveraging Tantivy’s proprietary antenna technology for mobile and fixed point applications; base stations, leveraging I-CDMA proprietary air-interface technology that is compliant to Cellular IS-95 spectrum standards, and a Wireless Internet Facility, providing all Operations, Administration, Maintenance & Provisioning (OAM&P) functions. Hanwha has served as the systems integrator, incorporating these components into Shinsegi’s existing network infrastructure as well as developing the 800MHz solution.
“I-CDMA is proving to be the most competitive and economic solution available today to enable users to wirelessly access full content of the Internet,” commented Young-Ki Kim, President of Hanwha Corporation/Network Division. “Its speed, capacity and coverage advantages will enable economical proliferation of true 3G capabilities throughout Korea.”
