Vancouver, Canada - June 4, 2002 - fSONA announces at SUPERCOMM the release of the SONAbeam™ 52-M - a carrier-class Free Space Optical (FSO) system that addresses the needs of wireless carriers today and into the future.

The SONAbeam™ 52-M is the first scalable-bandwidth FSO product to be offered in a carrier-class housing. It provides datarate-transparent transmission from 1.5 to 52 Mbps including NxT1/E1, DS3, E3, OC-1/STM-0 and SONET/SDH standards.

As mobile wireless networks migrate from second-generation (2G) to third-generation (3G) technologies, bandwidth requirements will grow dramatically. Predictions are that the worldwide number of cell sites will nearly triple over the next 5 years. Backhaul for these networks will need to be scalable to adapt to this growing demand for bandwidth. SONAbeam™ FSO technology offers a rate-adaptable, carrier-class solution that is a perfect fit for backhaul applications.

"By listening to our customers we discovered that wireless carriers are facing two challenges - the first is to minimize capital and operating expenditures in their current network, the second is to build that network to support an incremental migration to next-generation services." said Theresa Carbonneau, President and CEO, fSONA Communications. "Because the SONAbeam™ 52-M is able to multiply capacity as needed, carriers can update their network with FSO today and be ready to provide next-generation services in the future."

Replacing leased lines with FSO allows a mobile operator to install a scalable-bandwidth solution that is owned rather than leased. Bypassing the incumbents means wireless carriers are not tied to a recurring monthly expense that grows with each upgrade. The time and cost to secure licensing and address interference issues associated with microwave can also be circumvented by FSO - it is an unlicensed technology and, even in dense mesh configurations, there is no interference.

According to a September 2001 report by Strategis Group, FSO sales for backhaul are expected to grow from $34 million in 2000 to $627 million in 2006. Also, a November 2001 report issued by Bear Stearns, predicts Fixed-Wireless sales for backhaul are expected to grow from $4,150 million in 2000 to $6,482 million in 2005.

SONAbeam™'s FSO technology uses invisible light beams to deliver high-speed wireless communications that are reliable and secure. Rugged and robust, SONAbeam™ provides more power output than any other FSO product on the market. More power translates into greater availability and longer distance transmission.
