Tropos multi-mode 4.9 GHz/Wi-Fi Public Safety Mobile Broadband Solutions to be on display and Tropos Partners to Showcase Unique Applications

SUNNYVALE, CA, August 6, 2007 - Tropos® Networks, the market leader in metro-scale wireless mesh network solutions, announced today that it will be hosting a booth at the Association of Public-Safety Communications Officials-International, Inc. (APCO International) 73rd Annual Conference and Exposition. The conference, held in Baltimore, Maryland, will host over 2,500 public safety communication professionals from over 370 firms from around the globe. The conference spans from August 5 - 9, 2007, and will be held in the Baltimore Convention Center.

Tropos Networks will be exhibiting its new multi-mode 4.9 GHz/Wi-Fi MetroMesh fixed and mobile routers, designed to enable public safety agencies, municipalities and carriers to deliver a range of citywide IP-based data, video and voice applications. Tropos MetroMesh networks are deployed today for a range of public safety services including fixed and in-vehicle video surveillance, centralized database access (fingerprint, DMV, etc.), and sending in field reports and in cities such as Corpus Christi, TX; Tucson, AZ; and New Orleans, LA.

Select Tropos solution partners will also be on hand demonstrating their innovative IP based public safety applications using the reliable Tropos MetroMesh network infrastructure. Together, Tropos and its partners deliver field proven solutions for increasing the efficiency and effectiveness of public safety workers. Axis Communications, the global market leader in IP network video solutions, will be demonstrating its video surveillance solutions which when deployed can be used to monitor high crime areas, virtually increasing eyes on the street.

Shot Spotter will showcase their patented, state-of-the-art gunshot location and detection solutions for public safety and military applications. It provides fast and accurate detection and location identification of gunshots enabling fast response to potentially dangerous situations.

General Devices, the leading supplier of EMS communications and telemedicine equipment, will demonstrate their solutions used to send voice, data and images between ambulances and hospital staff enabling treatment of patients before they get to the hospital, saving time that can translate to saving a life.

"We are excited to be exhibiting our innovative 4.9 GHz/Wi-Fi Public Safety Networking Solutions at the APCO tradeshow," said Ron Sege, President and CEO of Tropos Networks. "With today's focus on homeland security, the services performed by first responders have never been more crucial. The ability to receive information in the field is critical, and Tropos' public safety solutions aimed at delivering increased effectiveness and efficiency accomplishes this goal."

The Tropos 4.9 GHz equipped MetroMesh routers are outfitted with both 4.9 GHz and 802.11b/g radios, and use Tropos' innovative SABRE policy-based routing. This allows public safety workers to access the network using either 4.9 GHz or 2.4 GHz devices, providing public safety agencies the flexibility to connect using more widely available Wi-Fi enabled devices, including laptops and PDAs, in addition to specialized 4.9 GHz devices. "With most municipal budgets as tight as ever, cost-effective solutions that improve the efficiencies of the existing public safety workforce are mandatory," said Sege.
