Rate-Adaptive SONAbeam™ 1250–M Adjusts Speed to Meet Specific Bandwidth Needs

Vancouver, Canada – January 13, 2003 - fSONA announces at the Wireless Communications Association (WCA) Technical Symposium in San Jose the release of the rate-adaptive SONAbeam™ 1250–M Free Space Optical (FSO) system for wireless communications.

The 1250-M, as well as the previously released 1250-S, provides wireless connectivity at either Fast (100/125 Mbps) or true Gigabit (1000/1250 Mbps) Ethernet speeds over ranges up to four kilometers (2.5 miles). This gives customers the ability to extend their networks with a product that adapts to their growing needs. Implementing a license-free, wireless solution that can be redeployed saves time and money for enterprise users and gives service providers flexibility in providing access to broadband customers. Currently the SONAbeam™ is in demand to provide backbone capacity for Wi-Fi networks – both for high-speed connections between nodes and to connect local Wi-Fi networks with the Internet.

“There are many optical wireless products on the market that serve up the standard telecom and business network speeds, however, the specialized speeds required by specific industries are often not accomodated,” says fSONA President & CEO, Theresa Carbonneau. “Our customers let us know they needed a product that could be customized to their specific applications. In keeping with our mission to provide simple solutions, we designed the 1250 series to be rate-adaptive and provide a range of speeds to better serve our customers.”

In addition to making the jump from Fast to Gigabit Ethernet, the 1250 series provides transmission from 34 up to 1500 Mbps for numerous
specialized applications. The signal is fully regenerated and reclocked (3R) at all data rates in this broad range to ensure the highest possible signal integrity. One example of applicability to a specialized application is the transmission of video. SONAbeam offers transparent network transport of various video standards including NTSC, PAL, HDTV, SDI, MPEG and DVB-ASI for Cable TV and Satellite companies, Film and Post-Production Facilities, Production Studios, Broadcasters or Internet Providers.

SONAbeam™ FSO technology uses invisible light beams to deliver high-speed wireless communications. By transmitting through the atmosphere, SONAbeam™ dispenses with the substantial costs of digging up sidewalks to install fiber. Transmission by SONAbeam™ eliminates the need to obtain costly radio frequency (RF) spectrum licenses, is immune to electro-magnetic/RF interference, and is virtually impossible to eavesdrop on or intercept.
