Tel Aviv, Israel, February 22, 2006 - Alvarion Ltd., (NASDAQ: ALVR), the world’s leading provider of wireless broadband solutions and specialized mobile networks, today announced a major network expansion by current customer, Irish Broadband, having received additional equipment orders totaling over $4 million for systems to be delivered through the second quarter of 2006. This network expansion enables Ireland’s leading, innovative wireless broadband service provider to nearly double its subscriber base by expanding its network coverage in Dublin and to eight other major cities in Ireland and Northern Ireland. To enable rapid growth and serve the full range of potential customers from residences and SOHOs to medium and large businesses, Irish Broadband is deploying broadband wireless equipment in both licensed and licensed-exempt frequency bands, including Alvarion’s BreezeMAX™ 3500—the worldwide leading WiMAX system, BreezeACCESS™ VL, and WALKair™3000 systems. This latest order makes Alvarion Irish Broadband’s largest broadband wireless equipment supplier.

As part of its network expansion plans, Irish Broadband and Intel recently announced a major initiative for the immediate rollout of WiMAX networks using BreezeMAX, which uses the BreezeMAX PRO—the world’s first CPE that uses the Intel WiMAX chip, to eight of Ireland’s major urban centers. Included in the WiMAX launch are the cities of Athlone, Arklow, Carlow, Ennis, Kilkenny, Letterkenny, Newbridge, and Wexford.

“Once we complete our network expansion, Irish Broadband will be a major regional service provider in Ireland offering thousands of subscribers the benefits of broadband,” commented Paul Doody, Managing Director of Irish Broadband. “This selection of Alvarion for both WiMAX and broadband wireless systems reflects our past successes with the company, its world class equipment and support, and makes Alvarion our sole WiMAX systems provider. We are also excited to be part of Intel’s worldwide WiMAX efforts, and in doing so, to be taking a leading role in the global acceptance of WiMAX and its deployment by carriers everywhere.”

As part of their worldwide WiMAX project, Intel selected Irish Broadband as one of sixteen strategic partners in sixteen countries to design, build and drive the development of WiMAX networks globally. Irish Broadband is the first company in this program to offer service on its WiMAX network.

BreezeMAX™ is Alvarion’s award winning, WiMAX platform that has been designed from the ground up according to the IEEE 802.16 standards using OFDM technology for advanced non-line-of-sight (NLOS) functionality. Its carrier-class design supports broadband speeds and quality of service (QoS) to enable carriers to offer triple play broadband services to thousands of subscribers from a single base station. Since its launch in mid-2004, BreezeMAX has been successfully deployed in over 150 installations in more than 30 countries around the world.

“Since 2002, Irish Broadband has been very successful using our market-leading systems to fill broadband coverage holes in Ireland," said Tzvika Friedman, CEO and President of Alvarion. “As an ’innovative challenger’ evolving its network to WiMAX, Irish Broadband is validating the coming growth in the broadband wireless market due to WiMAX standards, and Alvarion's role in this network expansion and as their only WiMAX provider shows our continued market leadership in wireless broadband. We are pleased that one of our key customers was chosen by Intel to be a strategic partner in its worldwide promotion and roll-out of WiMAX services, and we remain committed to supporting such partnerships, including the 30 other carrier customers now deploying Alvarion systems using the Intel chip.”

Alvarion’s system for license exempt spectrum is the BreezeACCESS VL, offering enhanced features such as OFDM for non-line-of-sight (NLOS) connections, extended reach of more than 20 kilometers (12.5 miles), high capacity, encryption, and quality of service (QoS) mechanisms for carrier-class broadband data and voice services. With its advanced features such as 10 and 20 MHz channels and automatic clear channel selection (ACCS) with a built-in spectrum analyzer, BreezeACCESS VL enables flexibility in frequency planning.
