Systems Integrated Expands LA County Traffic Control System Using Proxim Tsunami® GX800 Licensed Radios

Silicon Valley, CA (October 17, 2011) – Proxim Wireless Corporation (OTC Markets: PRXM), a leading provider of complete outdoor wireless backhaul systems, today announced the addition of Proxim Tsunami® GX800 licensed point-to-point radios to the existing 13 city-wide traffic control system deployment for Los Angeles County, California. This traffic control system already won a 2009 National Association of Counties Achievement Award for saving LA County an estimated $7.0 million in costs over tradition copper or fiber optic installations.

“To enable LA County to reduce the number of leased telephone lines and, more importantly, to provide high-capacity communications over a non-contiguous geographic area spanning hundreds of square miles, we needed to be able to transmit all the traffic control system data and video images back to the LA County Traffic Management Center. Fiber was not feasible and too costly to install so Proxim GX800 18GHz radios were deployed,” stated Jane White, Senior Civil Engineer, LA County.

“The 320Mbps FDD capacity was just what we needed, and the product was very easy to deploy,” stated Larry Pomatto, President, Systems Integrated. “All of the Proxim products are centrally managed and with extensive support for licensed radio frequencies available, choosing the Proxim GX800 was a simple decision.”

“The Tsunami GX800 is available in a wide variety of frequencies from 6-38GHz worldwide and will be on display at this year’s ITS World Congress in Orlando from October 16-20. We are exhibiting at ITS booth 1202 and with our extensive wireless product line, we can provide customers with a complete solution for their ITS projects.” said Geoff Smith, Proxim’s VP of Sales for the Americas.
