TEL AVIV, Israel, December 8, 2008 — Alvarion Ltd. (NASDAQ:ALVR), the world’s leading provider of WiMAX™ and wireless broadband solutions, today announced that it will implement proactive cost reduction initiatives aimed at lowering the company’s breakeven point to help preserve profitability in the slowing global economy, while also maintaining its capability to continue growing if business conditions support growth.

As part of this series of initiatives, the company plans to reduce its global workforce by approximately 11%, from a base of about 1000 employees. In addition, Alvarion is implementing company-wide measures including management salary reductions. The combined initiatives are expected to generate annual cost of goods and operating expense savings of about $15 million. Alvarion expects these initiatives to be implemented before the end of the year and expects to take a one-time charge of approximately $3 million in the fourth quarter of 2008. This charge was not included in the company’s fourth quarter earnings guidance provided on November 3, 2008. Except for the one-time charge, the outlook for the fourth quarter remains unchanged.

Mobile WiMAX is now primed and ready for clearly defined markets. The standard is in place, components are available, and regulatory conditions are favorable for industry growth and adoption. New report from WTRS identifies winning markets, drivers and challenges for WiMAX within the wider wireless broadband arena.

Mountain View, CA December 1, 2008 - Fueled both by consumer demand for entertainment and communication as well as governmental regulatory and economic incentives, companies at all levels of the broadband services and infrastructure value chain are developing new technologies and enabling new services that will continue to push the US broadband market forward over the next 4-6 years.

"Recent economic uncertainty will affect the consumer market but will not greatly influence the adoption of WiMAX and other emerging wireless technologies in communications sectors," according to Kirsten West, principal analyst with WTRS. "One exception to this is the emergence of WiMAX services targeted at the mobile professional, empowering the connected laptop 'on the go'. This is an application which will likely be negatively impacted by reduced corporate spending due to expense controls that will negatively impact the roll-out and applications targeting the mobile professional."
