Cites AB-Access(TM) as Vital to its Business Strategy

Adaptive Broadband(TM) Corporation (Nasdaq National Market: ADAP) announced today that it had signed a $225 million, five-year contract to provide its AB-Access fixed wireless broadband equipment to Colorado-based Telecom Wireless Corporation (TWC) (OTC BB: NOYR).

TWC's business plan focuses on the convergence of video, voice and data in order to bring broadband connectivity, content and e-commerce over a wireless platform through the Internet to residential and business customers in both the United States and abroad.

AB-Access Key to E-Commerce, the Internet Growth Driver

"Adaptive Broadband's AB-Access product is a key element in TWC's strategy to deploy a digital wireless platform enabling us to provide competitive product and service offerings to contend with our national competitors," said Calvin D. Smiley, president, Telecom Wireless Corp. "This will position TWC to provide an affordable and reliable 'last mile' solution for business and residential subscribers, which traditionally has been offered by the Regional Bell Operating Companies, or RBOCs." "We have tremendous confidence in Adaptive's AB-Access product and feel that it is a significant cornerstone to TWC becoming a next-generation communications company delivering high speed data and access solutions globally."

"Business-to-business e-commerce will account for 80% of Internet traffic five years from now, according to industry reports. To succeed in the e-commerce arena, two-way, high-speed transmission of multimedia applications is mandatory. AB-Access, with its current high-speed data rate of 25Mbps and planned 100Mbps this year, offers superior broadband wireless data networking capabilities. It's abundantly clear that AB-Access is an e-commerce enabler," stated Frederick D. Lawrence, chairman and chief executive officer of Adaptive Broadband.

About AB-Access

AB-Access bridges the last mile, replacing the local loop for business and residential subscribers. It offers data transmission at rates up to 25 Mbps, which provides the capability for real-time video conferencing, transmission of full streaming video, web surfing, and transmission of data files - all simultaneously and over one connection. Product bandwidth is planned to expand to 100 Mbps in mid-2000.

AB-Access technology spans the frequency range from 2 to 42 GHz. The first releases for AB-Access are for applications using the 5 GHz U-NII (Unlicensed National Information Infrastructure) and 2.5 GHz MMDS (Multi-channel, Multi-point Distribution Service) frequency bands. Telecom Wireless Corporation licenses MMDS spectrum in Florida and will conduct a marketing trial with Adaptive's MMDS product. Adaptive Broadband plans to introduce an AB-Access product for the 3.5 GHz market in Europe during the first quarter of 2000.

Point-to multipoint wireless networks being deployed with AB-Access include transmission hubs that contain six transmitter/receivers, each having 60-degree access points for complete 360-degree coverage. These access points are each serviced by an ATM-configured transceiver with a 25 Mbps channel, which can be shared by up to 256 active service users because bandwidth is dynamically assigned. This scheduling is made possible by the product's proprietary MAC (media access control) software, as well as by ATM's small fixed cell length. The technology allows bandwidth to be supplied with cell-by-cell precision, essentially providing packet-on-demand capability. The ultimate result is that bandwidth of up to 25 Mbps is readily available to all users on the network.
