ITU TELECOM WORLD 2003

SAN JOSE, Calif.--(BUSINESS WIRE)--Oct. 7, 2003

ArrayComm, the world leader in mobile broadband wireless and smart antenna technologies, announced today that Kyocera will unveil its commercial iBurst(TM) Personal Broadband base station at ITU Telecom World 2003 in Geneva. Kyocera Corporation, the developer and manufacturer of the base station, is now producing the equipment in volume to support the commercial launch of iBurst services by Personal Broadband Australia (PBBA) in Sydney as well as trials in Korea, China, the US, and Europe. Visitors to Kyocera's booth (#5001.010 in the Japan Pavilion) at Telecom World 2003 can experience true personal broadband for themselves, using Kyocera's PC-card modems to connect with the iBurst base station for up to 1 Mbps mobile Internet access.

Kyocera's base station implements the latest iBurst protocol from ArrayComm and takes maximum advantage of ArrayComm's patented IntelliCell(TM) smart antenna technology. The iBurst base station is the only mobile broadband wireless solution to use fully-adaptive antenna array processing, yielding the industry's highest spectral efficiency and capacity -- in excess of 20 Mbps of aggregate throughput per each 5 MHz of spectrum in real-world multicell deployments, with proven several-kilometer ranges. The base station is designed for enclosureless outdoor deployments and is optimized for the rooftop sites most common in initial-stage urban iBurst networks.

"The splendid performance of Kyocera's equipment in our recent trials far exceeded our expectations," said Charles Reed, CEO of PBBA. "With the general release of the production base station, and the confidence in the iBurst system its performance has fostered, all the pieces are in place for our commercial launch later this year."

"The PBBA trial's success and the other operators with whom we're now engaged indicate tremendous market potential for iBurst Personal Broadband worldwide," said Junichi Jinno, Executive Officer and General manager of Kyocera's Communication Systems Equipment Division "We are anxious to introduce the system to an even broader audience at Telecom World 2003."

"The iBurst system was designed to maximize service capability per operator dollar of network and spectrum investment," added Marc Goldburg, ArrayComm's CTO. "The robust results Kyocera's equipment is delivering attests to the success of the system's design as well as Kyocera's world-class manufacturing and product support capabilities."

The iBurst base station is currently configurable for operation in the 1.9 GHz and 2.3 GHz spectrum bands, with others in the pipeline.

About the iBurst Personal Broadband System

The iBurst Personal Broadband System is a carrier-grade wide area wireless data network designed to provide high-speed Internet access wherever people want it. Distinct and complementary to traditional 2G and emerging 3G systems as well as short-range 802.11 WLAN (WiFi) networks, Personal Broadband technology delivers a revolutionary Internet experience, combining the freedom of mobility, low cost infrastructure, and transmission speeds similar to a typical home broadband DSL or cable line. The system is architected to support the full range of IP applications in a mobile environment, including e-mail, virtual private networking, high speed Web access, streaming video and on-line gaming. ArrayComm's patented smart antenna technology is at the heart of the system, providing dramatic gains in coverage and capacity and the industry's lowest-cost mobile broadband system.
