SONAbeam Free Space Optics Proven Transport Solution for Base Station Hotels and Indoor Wireless Applications

Minneapolis and Vancouver, Canada – July 8, 2003 – ADC (NASDAQ: ADCT) and fSONA Communications today announced that SONAbeam™ free space optics systems have successfully completed compatibility testing at ADC’s testing facility in Minneapolis and are fully qualified for use with ADC’s Digivance™ family of digital wireless coverage solution products.

The Digivance system expands network coverage while providing a significant cost savings to wireless carriers. By deploying the “Base Station Hoteling” architecture, carriers can centralize base-station equipment and rapidly deploy antennas where coverage and capacity issues exist. Digivance then transports wideband RF via digital optical signals over fiber or free space optics to economically expand coverage and capacity. Digivance also solves the difficult challenge of covering entire buildings or campus facilities. With the installation of this low-cost, high-quality solution, wireless carriers can quickly and cost-effectively deliver coverage to corporate facilities and other buildings where mobile users demand service.

Combining SONAbeam and Digivance eliminates the need for high cost fiber construction and allows for the rapid deployment of new capacity coverage required by wireless service providers. SONAbeam high-performance free space optics systems are the perfect solution for wireless operators to extend coverage and increase capacity. Designed for carriers from day one, the SONAbeam series operates using the “eye-safe” 1550nm laser wavelength. Operating at 1550nm allows SONAbeam to deliver exceptionally high transmit power and link margins which translates into longer ranges and superior availability through all weather conditions.

“Digivance provides wireless carriers with a variety of new, low-cost options to extend coverage and capacity to their networks where it’s needed,” said Jeff Quiram, president of the Wireless Business Unit for ADC. “Integrating SONAbeam Free Space Optics with Digivance markedly increases the potential locations for remote antennas and indoor wireless coverage solutions.”

“ADC’s Digivance provides a path for wireless carriers to take a major step forward in network efficiency for their mobile networks and indoor wireless requirements extending both coverage and capacity and improving the quality of service for their customers,” said Mike Corcoran, senior vice president of sales and marketing for fSONA. “fSONA believes that, with fSONA’s free space optical transmission system as a transport option, Digivance will make a significant impact in the marketplace and is extremely pleased to support the solution with SONAbeam. Supporting an innovative solution like the Digivance is especially satisfying as it parallels the work of fSONA to create economical solutions for carriers to expand and enhance the quality, capacity, and coverage of their networks.”
