Companies partner to provide high speed optical wireless Ethernet solutions with Link Protection and Restoration capabilities for both Fast Ethernet and Gigabit Ethernet networks.

McLean, VA, Merrimack, NH, - February 8, 2006 - fSONA Systems and Metrobility Optical Systems today announced a highly robust, fully redundant, carrier class optical transmission solution for point-to-point wireless broadband systems. The solution combines Metrobility's line of Ethernet-based Radiance LPR (Line Protection and Restoration) products with fSONA's SONAbeam™ leading edge optical wireless system to extend all the benefits of free-space optical transmission with the peace of mind that comes from having a fully redundant service.

The SONAbeam™ used in conjunction with the Radiance LPR systems provides a greater breadth of redundant solution options than has ever been offered before. This marriage of technologies offers the ability to use virtually any other existing Ethernet bridging solution (be it fiber or RF) to provide the most robust point-point communications platform available anywhere.

“fSONA’s innovative application of Metrobility’s LPR system further confirms the importance of redundant and protected paths in any network,” states Steven Curtis, senior vice president of sales and service for Metrobility. “We have been providing redundancy to mission-critical LANs found in the financial and manufacturing communities for years and have recently seen an increase in the demand for protected services in wireline carriers. Through our partnership with fSONA, wireless customers now benefit from the same type of highly-available, high-speed network.”

Extensive interoperability testing between the two company's products has already been completed at the fSONA manufacturing and engineering facilities with excellent results.

“We recognize Metrobility as an industry leader in specialized optical interface devices for the Ethernet world and their Radiance LPR systems provide the redundant path management solutions required for a carrier class wireless operating environment. fSONA sees the marriage of the technologies as one that simply makes sense and we look forward to working together,” says Sunny Taylor, President and CEO of fSONA Systems; also adding “We see a great opportunity to broaden the scope of both company’s capabilities by working together, not only with our existing products, but in the potential for future joint development efforts.”

Metrobility offers patented LPR solutions that support 100Mbps, 1Gbps, and CWDM options. These solutions fail over to a secondary link in as little as 200microseconds in case of a loss of link. With the company's SONAR (Switch on No Activity Received) technology, the device also senses loss of traffic to protect the network against a failed switch.
