Costa Rica Enjoys Extended Broadband Wireless Services with Alvarion's 4Motion Solution

TEL AVIV, Israel -- Alvarion Ltd. (NASDAQ: ALVR), the world's leading provider of WiMAX and wireless broadband solutions, today announced that RACSA, a leading operator in Costa Rica, selected its 4Motion(TM) solution to provide extended wireless access services to business and residential customers in several major cities in Costa Rica. Coasin is Alvarion's local partner for this deployment project.

Using the award-winning BreezeMAX(TM) platform as its radio access network (RAN), Alvarion's 4Motion solution operates at 3.5 GHz and allows RACSA to offer reliable, high-speed voice and data services to Costa Rica's urban and rural areas. 4Motion is the foundation of Alvarion's all-IP OPEN(TM) WiMAX ecosystem, which combines BreezeMAX and best of breed systems for creating an operator-centric network solution for WiMAX.

As a government-authorized operator in one of the top countries in Latin America for Internet use, RACSA chose Alvarion for its well-known WiMAX expertise and rapid time-to-market advantage, enabled by the availability of the 4Motion. With this successful network deployment, subscribers are now able to connect easily and quickly, benefiting from high-quality service in both dense and very remote areas.

"As we expand our WiMAX network deployments in Latin America, we welcome RACSA's project for the 3.5 GHz frequency using our WiMAX solution," said Tzvika Friedman president and CEO of Alvarion. "Our OPEN WiMAX strategy enables RACSA to provide its growing list of subscribers with innovative wireless network solutions anywhere, anytime, and at affordable prices."
