Adaptive Broadband Teams With SAIC to Integrate AB-Access Into Next Generation Networks.

Next Generation Information Networks Initiative Focused on Government

Applications & Large Commercial Users

SUNNYVALE, Calif.--(BUSINESS WIRE)--Oct. 5, 1999--

ADAPTIVE BROADBAND CORPORATION (Nasdaq National Market: ADAP) announced it has signed an agreement with a new systems integrator for its AB-Access(TM) wireless data networking equipment. Science Applications International Corporation (SAIC), San Diego, Calif., will employ AB-Access in its Next Generation Information Network initiative for government applications and large commercial clients around the world. SAIC is a Fortune 500 company and the nation's largest employee-owned research and engineering firm.

Business Plan Milestone

"This agreement marks another important milestone in our strategic business plan," said Frederick D. Lawrence, president and chief executive officer of Adaptive Broadband. "This is an entirely new channel to market for AB-Access. SAIC is a market leader in system integration, bringing together legacy protocols and new technologies onto an IP platform. Their expertise will quickly bring the value of AB-Access to corporate and government clients.

"SAIC will also dramatically increase our marketing strength for this product on an international basis," he continued. "Including its subsidiaries, SAIC has a team of more than 38,000 employees and offices in over 150 cities around the world. The resources of SAIC will help us achieve rapid market penetration with the `first in' technology provided by AB-Access."

Turnkey Support

"With this agreement, SAIC will be able to turn-key end-to-end broadband wireless networks, supporting converged video, voice, and data," said Carl Silva, Corporate Vice-President for SAIC's Next Generation Information Networking initiative.

"SAIC provides its clients with turnkey network support, building out back offices to integrate hardware and software solutions," he continued. "It also provides its clients with network and product training, software development and service bureau operations. This will now be a broadband wireless technology incorporated into networks designed for selected SAIC clients. Adaptive Broadband and SAIC will also undertake joint marketing activities to build demand for the new technology in these markets."

Speeds Up To 25 Mbps

AB-Access was introduced earlier this year for ultra high speed Internet access. It offers data transmission at rates up to 25 Mbps, a speed up to 400 times faster than dial-up service with a 56K modem. At this bandwidth, users can download full-streaming video, download data files, use real-time video conferencing and surf the Worldwide Web all at the same time over a single connection. Service providers in Florida and Texas are currently introducing commercial applications for data transport using the unlicensed U-NII band, which is available today for two-way transmission.

SAIC can begin providing integration support for AB-Access immediately in the United States in the U-NII band. AB-Access is also available for use in the licensed MMDS frequency, which will be available to carriers pending further FCC action to finalize two-way transmission capability in that band. SAIC also will support integration and back-office systems internationally for a range of other frequencies. Adaptive Broadband has planned product releases at several frequency bands between 2 and 42 GHz, which are made possible by the frequency-independent platform architecture of the product.

Bundled Voice and Data

This technology also provides an effective platform for the bundling of voice and data over the Internet. During August, Adaptive Broadband worked with the Information & Telecommunication Technology Center at the University of Kansas, Lawrence, Kan., to successfully demonstrate wireless transmission involving simultaneous, point-to-multipoint voice and data traffic using Internet protocol (IP). "That demonstration showed how voice and data can be effectively bundled over the Internet," said Dr. Daniel Scharre, chief technology officer for Adaptive Broadband. "For users, it means they can enjoy real-time voice service over their Internet connection while simultaneously Web browsing, downloading files, or sending data over that same connection. And for carriers, it opens a whole new world of service bundling in the markets for Internet access and local telephone voice service. And all this can be done while maintaining appropriate quality of service for both real-time and non-real-time services."

Converging Technologies onto IP Platform

"Adaptive Broadband's technology provides a strategic fit within our convergence initiatives, where we help our clients drive legacy protocols and new technologies to IP," said Alex Tosheff, Technical Director for SAIC's Next Generation Information Networking initiative. "There's a lot of innovation in the access networks, and we are working with our enterprise customers to make use of these types of broadband services to reduce infrastructure costs and stay competitive."

"SAIC is seeking out emerging players like Adaptive Broadband," Tosheff added. "It's in our clients' interests to investigate the use of leading-edge technologies."
