ArrayComm and KT Complete Initial Phase of Ongoing i-BURST Trial.

Business Editors/High Tech Writers

SAN JOSE, Calif. and SEOUL, South Korea--(BUSINESS WIRE)--Jan. 24, 2003

ArrayComm, Inc. and the leading Korean telecommunications operator KT today announced that they have successfully completed the initial phase of an i-BURST(TM) Personal Broadband System trial. The South Korean field trials, which took place over several months, included highly successful testing of the system's wide-area wireless broadband capabilities, including data speed, range, scalability, capacity, and interoperability with wireless LAN "Wi-Fi" service. With trial systems supplied by Kyocera Corp., four companies -- KT, ArrayComm, LG Electronics and Kyocera --jointly performed testing during the trial.

"We expect our new wireless Internet market business in the 2.3 GHz frequency band, in combination with our wireless LAN-based Nespot service, to grow substantially over the next few years," said Deok-Rae Lim, vice president of KT's Service Development Laboratory. "Given the size of this market opportunity, we sought out the i-BURST system for this long-term, resource-intensive testing, and ArrayComm has set a very high benchmark for performance. It really does provide consumers with their own personal broadband connections, and that opens up many new potential markets for our services."

Following this successful initial phase, KT plans to evaluate the i-BURST system's service capabilities using multiple cell sites in a dense urban environment. The evaluation is scheduled for the first half of 2003 and will include interactive video/data conferencing, voice over IP (VoIP), gaming, wireless LAN (Wi-Fi) interoperability, Web surfing and video streaming. This evaluation is being held in advance of Korea's development of services in the 2.3 GHz frequency band, with key spectrum usage decisions expected later this year.

South Korea leads the world in broadband adoption, with 57 percent of all households and 76 percent of Internet households using a broadband connection. This contrasts with other developed nations such as the United States, where only 13 percent of households and 22 percent of Internet households have broadband.

KT's field trials with ArrayComm took place at two sites: Myong-Dong, a densely urban section of central Seoul, and Yang-Pyung, a rural area about 70 kilometers (44 miles) outside Seoul. KT provided space and equipment in its central office facilities for base stations provided by Kyocera, along with new fiber lines, computers and other equipment to ensure a robust test. Since the i-BURST system is a pure IP, end-to-end system, no customization at KT's central office locations was required.

"We are impressed not only with the technical capabilities of the i-BURST system, but also with its ease in moving from local area to wide area coverage," added Mr. Lim. "The i-BURST system can act as a cost-effective broadband alternative for areas not reached by our ADSL service, as well as a compelling 'untethered' service for our current broadband customers."

Technical achievements in the trials included proven, consistent individual data rates of 1 Mbps and 10 Mbps of total throughput in only 2.5 MHz of spectrum. KT and ArrayComm also showed seamless handoff between wireless LAN "Wi-Fi" coverage and wide area i-BURST coverage, as well as smooth interoperability with KT's Nespot VoIP commercial service.

"KT has committed to deliver the best possible services to their customers across Korea," said Martin Cooper, chairman and CEO of ArrayComm. "They understand that consumers will want their Internet service wirelessly when they can have high speed at an affordable price. We're looking forward to continuing and strengthening the strong foundation our companies have built together."

About KT

KT was founded on Dec. 10, 1981, to contribute to social welfare and convenience in everyday life by operating an efficient telecommunications service and developing telecommunications technology. KT announced the space communications era by launching Korea's first satellite, Koreasat 1, followed by Koreasat 2 and 3 over the next few years. KT led Korea into the information age as the nation's major communications company.

KT's broadband service (Megapass) caused a great sensation in the domestic high-speed Internet market. Megapass surpassed 5 million subscribers in Jan. 16, 2003, with a domestic market share up to 48%. KT wrapped up the privatization process selling the entire government stake. KT promotes 2.3 GHz Portable Internet service as one of four key businesses in 2003. KT will be reborn, not as the public telephone company, but as a progressive and creative company that will lead the way in the global information and telecommunications field.
