SAN JOSE, Calif.--(BUSINESS WIRE)--Jan. 14, 2003

ArrayComm is Industry's First to Demonstrate Broadband

Internet Session Handoff in Mobile, Real-World Conditions

ArrayComm, Inc., today announced that it has demonstrated seamless handoff of i-BURST(TM) Personal Broadband user sessions near its San Jose, Calif. headquarters. This is the industry's first demonstration of Internet session handoff at broadband speeds between field-deployed base stations. The i-BURST system's handoffs between base station coverage areas provide consumers with continuous video streaming, file transfer, e-mail and other standard Internet applications while walking, driving or standing still. The i-BURST system provides the freedom of wireless and the speed of DSL at the cost of a dial-up connection.

"Seamless handoff between base stations is a critical component of a mobile broadband Internet access system," said Shiv K. Bakhshi, Ph.D., research manager for wireless and mobile infrastructure at IDC. "Availability of a fast and stable personal broadband connection across a neighborhood or city will invite greater data usage and legitimize a culture of data consumption in a mobile environment. And that, in turn, will open up significant new market opportunities for wireless operators, application providers and service providers."

Providing a solid infrastructure for commercial wireless broadband service, the i-BURST Personal Broadband System is a pure IP, end-to-end system designed much like a cellular system. It includes base stations deployed throughout a coverage area and wireless modems or PC cards used by consumers to access the service. The network uses standards-based technology to manage mobility across large cities for thousands of subscribers. It also seamlessly interoperates with wireless LAN "Wi-Fi" networks in the home, office or public "hot spot" to provide full ubiquity of service.

During the handoff demonstration, ArrayComm used an i-BURST wireless modem attached to a laptop computer. While driving between its San Jose headquarters base station and another one 4.5 kilometers (approximately 3 miles) away, the ArrayComm team streamed a live Yahoo video feed, transferred a large file via FTP, and conducted several other typical Internet sessions at broadband speeds. In each case, the handoff was transparent to the user while demonstrating low latency and high reliability on the network. Since each i-BURST base station has a range of many kilometers, this handoff capability enables consumers to freely move and communicate from one end of an i-BURST-enabled city to the other utilizing its high-speed Internet access, just as they experience wireless voice calls today.

"We have demonstrated the i-BURST system's ability to travel at walking and driving speeds countless times, and now we have shown its ability to travel across a city as well," said Martin Cooper, chairman and CEO of ArrayComm. "We have designed a network designed for consumers, so they can travel where they want and use the computing devices that they know. We will first scale the i-BURST network for consumers in Australia, providing contiguous coverage across Sydney, with availability in other parts of the world not far behind."

"This latest demonstration proves that the i-BURST system provides true transparency of location in addition to its transparency to IP, regardless of the end user's IP device, application or location in the network," said Marc Goldburg, ArrayComm's chief technology officer. "The handoff process is standards-based to ensure ease of integration with other network functions such as billing and quality of service management. From the client side, handoff is managed by the i-BURST modem. No special hardware or software is required on the user's laptop or PDA."

The i-BURST system will expand its wide-area mobility demonstration during the pre-commercial deployment of the system currently underway in Sydney, Australia, through ArrayComm subsidiary CKW Wireless. The pre-commercial deployment includes an expected 12 base stations covering 150 square kilometers (approximately 60 square miles) in Sydney. CKW plans to transition the pre-commercial phase into a full commercial service by mid-2003.

About the i-BURST Personal Broadband System

The i-BURST Personal Broadband System is a carrier-grade wide area wireless data network designed for people to have high-speed Internet access wherever they are. Distinct and complementary to traditional 2G and emerging 3G systems as well as short-range 802.11 WLAN (Wi-Fi) 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, gaming and voice over IP (VoIP). ArrayComm's patented adaptive antenna technology is at the heart of the system, providing incredible gains in spectral efficiency and thereby dramatically lowering per-user service costs on a network.
