Alvarion and Tropos Partner to Deliver Innovative Municipal Wireless Broadband Solutions; Partnership Combines Companies' Market Leading Technologies and Products to Offer Cost Effective, Easy to Deploy Broadband Networks.

MOUNTAIN VIEW, Calif. & SUNNYVALE, Calif. -- Alvarion Ltd., (NASDAQ: ALVR), the world's leading provider of wireless broadband solutions and specialized mobile networks and Tropos, the world's leading provider of Wi-Fi mesh systems, today announced their agreement to jointly target the municipal broadband market with a combination of their market leading technologies and products to enable municipalities to easily deploy cost effective broadband networks.

Combining Alvarion's recently released BreezeACCESS(TM) 4900 for the 4.9 GHz band licensed for the U.S. public safety market and its market leading BreezeACCESS(R) VL for the 5 GHz unlicensed band with Tropos's field proven MetroMesh(TM) Wi-Fi products, offers municipalities the ability to quickly and inexpensively deploy broadband, from access to backhaul, as a single flexible, robust network. Since the combined solution supports both fixed and mobile users, customers benefit from both companies' expertise in engineering and design of complex municipal network architectures. The companies are already jointly engaged in numerous high profile projects across the U.S.

"With the intense public sector interest in broadband applications, combining our market leading wide area broadband solution with Tropos' Wi-Fi mesh systems creates a unique offering for municipalities and other government organizations wanting to implement broadband," commented Amir Rosenzweig, President of Alvarion, Inc. "The broadband capacity, advanced security, and non line-of-sight performance of the BreezeACCESS 4900 for licensed public safety deployments and the BreezeACCESS VL for deployments using the 5 GHz unlicensed band make them ideal systems for multipoint backhaul of the Tropos MetroMesh access clouds. Together, we have greatly strengthened our position toward immediate and future municipal opportunities."

With advanced OFDM technology, the BreezeACCESS platform enables high-capacity, non line-of-sight connections, while offering a host of advanced features to support scalability and advanced applications like VoIP and video. Enabling point-to-multipoint backhauling of Wi-Fi mesh clouds, BreezeACCESS systems can also be used to access devices such as sensors, cameras and traffic systems located throughout a city. To meet the rigorous security demands of public safety networks, BreezeACCESS 4900 is FIPS-197 certified and employs federally approved AES encryption.

"We expect great opportunities from the partnership between Tropos and Alvarion," said Ron Sege, CEO of Tropos Networks. "Our customers demand flexible and reliable wireless broadband solutions, and this agreement allows us to continue building best-of-breed metro-scale Wi-Fi mesh systems, while leveraging Alvarion's multipoint expertise to supply the capacity injection into the mesh clouds using a combination of 4.9 GHz, licensed and 5 GHz, unlicensed spectrum. Our combined experience in this market is completely unmatched, which adds tremendous value to this offering and creates a win- win situation, for Tropos, for Alvarion, and especially communities across the country."

Tropos MetroMesh is the world's most deployed Wi-Fi mesh solution, offering municipalities an economically compelling alternative for providing broadband access to mobile municipal workers, residents and small businesses. Municipal police, fire and EMS departments have been among the first to adopt metro-scale Wi-Fi mesh networks. High-speed, in-field data access dramatically improves public safety officer effectiveness and efficiency by getting critical information in their hands on the street. Additionally, the open-standards Wi-Fi access of the Tropos MetroMesh architecture allows diverse revenue possibilities for municipal and service provider customers.
