4Motion(TM) Achieves Successful Interoperability in Preparation of Wave 1 & 2 802.16e-2005 Certification

TEL AVIV, Israel -- Alvarion Ltd. (NASDAQ: ALVR), the world's leading provider of WiMAX and wireless broadband solutions, announced the expansion of its OPEN WiMAX ecosystem through successful initial interoperability testing with an increasing number of 3rd party mobile devices. The company's 4Motion solution has achieved successful initial interoperability with numerous devices, using embedded chipsets from top vendors such as Beceem Communications, GCT Semiconductor, Intel Corporation, Runcom Technologies and Sequans Communications, all in preparation of Wave 1 and 2 802.16e-2005 certification.

Providing high quality radio performance and answering to the strict security measures incorporated into the WiMAX and 802.16e-2005 specifications, Alvarion has completed yet another significant technology milestone in its interoperability testing program. The successful testing of WiMAX security features with other vendors includes authentication and data encryption methods, as well as radio resource management features, automatic power control and channel quality management.

With this extensive portfolio of compatible Mobile WiMAX chipsets, the 4Motion solution will have the ability to support a wide range of end-user devices such as laptops, PDAs, handsets and WiMAX PC cards. Compliant with WiMAX Forum(TM) 802.16e-2005 specifications and following a recent and advanced series of interoperability tests, 4Motion has demonstrated support for rich media centric content services such as Mobile TV, VoIP, VOD, and interactive gaming.

Designed as open, standard, and interoperable, OPEN WiMAX is a complete ecosystem that encompasses network equipment, consumer electronics, service offerings, and even the end-users' experience. Referring to Open Personal Broadband Networks, OPEN WiMAX is the ecosystem behind Alvarion's highly scalable 4Motion solution, which combines the BreezeMAX(TM) and best of breed systems from various partners to create an operator-centric network solution for WiMAX.

"4Motion offers extensive capabilities for Mobile WiMAX networks and devices, and is designed to support next generation WiMAX solutions," said Rudy Leser, Alvarion's corporate vice president of strategy and marketing. "Alvarion positions itself as market leader by demonstrating interoperability with leading vendors and presenting an integrated solution. Service providers prefer to choose best of breed systems from a variety of vendors, as well as create an interoperable network for widely available handsets and consumer electronic devices, thus meeting their specific network requirements and subscribers' needs."

Today's WiMAX technology demands full interoperability among vendors, forming a new market approach and placing the operators and consumers in the center. With the vast potential in WiMAX networks, more and more leading vendors are taking an active role in WiMAX Forum activities to further reinforce the OPEN WiMAX ecosystem.
