                                                           FOR IMMEDIATE RELEASE


              ALVARION FIRST TO DEMONSTRATE WORKING CPE USING INTEL
                                   WIMAX CHIP
          BreezeMAX(TM) 3500 with Intel(R) PRO/Wireless 5116 Showcased
      in a Lab Trial During WiMAX Forum's Face2Face Event in Malaga, Spain
                                       ---

Tel Aviv, Israel, April 18, 2005 - Alvarion Ltd. (NASDAQ: ALVR), the world's
leading provider of wireless broadband solutions and specialized mobile
networks, today announced the first lab demonstration of a working WiMAX-ready
CPE using the Intel(R) PRO/Wireless 5116 broadband interface. Alvarion has now
successfully integrated the PRO/Wireless 5116 into its BreezeMAX(TM) 3500 CPE,
the culmination of a strategic development effort with Intel, which began in
mid-2003.

Major operators, systems integrators, and other WiMAX Forum members
participating in the event had an opportunity to observe the live demonstration
of the system at the Cetecom laboratory during the organization's Face2Face in
Malaga, Spain last week. Cetecom is the first lab selected by the WiMAX Forum to
perform certification testing of WiMAX equipment. Iberbanda, a Spanish service
provider that has already commercially deployed BreezeMAX in several regions of
the country, supplied a network connection as part of the demonstration.
"Continuing our leadership of the broadband wireless access market, we are now
the first equipment vendor to demonstrate a working WiMAX-ready CPE using the
Intel(R) PRO/Wireless 5116 broadband interface," said Zvi Slonimsky, CEO of
Alvarion. "With the product slated for commercial release in the second half of
2005, this milestone represents a significant step forward for both Alvarion and
the industry as we move to widespread adoption of WiMAX standard products."

Intel(R) PRO/Wireless 5116 broadband interface is a system-on-chip that supports
WiMAX last-mile connectivity to homes and businesses. Leveraging the ratified
IEEE 802.16-2004 specification, the Intel chip and Alvarion system provide
high-throughput broadband connections over long distances. WiMAX can be used for
a number of applications, primarily "last mile" broadband connections.

"We have worked with Alvarion since our early days of focusing on WiMAX," said
Scott Richardson, General Manager Broadband Wireless, Intel. "The incorporation
of our Intel(R) PRO/Wireless 5116 broadband interface into their BreezeMAX CPE
reflects our mutual commitment to WiMAX. We will continue to promote this
technology together, making WiMAX a mass market phenomenon," he added.

Since its launch in June 2004, the WiMAX-ready BreezeMAX 3500 is operational
across the European continent with operators such as Altitude Telecom in France
and Iberbanda in Spain, and with additional carriers around the world.

"Our business model is focused on providing broadband to rural and urban areas
that are currently not served and have difficulty getting DSL," said Carlos
Morell, CEO of Iberbanda. "Until now, we have been concentrating our efforts on
delivering critical access to large enterprises- a strategy which has proved to
be highly successful. With WiMAX, we can achieve the proper economics to serve
smaller business customers and residential users, and BreezeMAX is the key to
rolling out broadband services to these types of users."

BreezeMAX(TM) is an OFDM platform with advanced NLOS functionality designed for
operators to offer broadband IP-based data and voice services, allowing for the
easy, cost-effective evolution of networks to WiMAX standard solutions. Its
carrier-class design supports high quality of service (QoS) and broadband speeds
to enable carriers to offer multi-services to thousands of subscribers in a
single cell.

             MICROCOM, ISP IN DEMOCRATIC REPUBLIC OF CONGO, FIRST TO
            DEPLOY ALVARION'S WIMAX-READY NETWORK IN CENTRAL AFRICA
    BreezeMAX(TM) 3500 to Provide Corporate and Resident Users with Broadband
                                Internet Service

                                       ---

TEL AVIV, Israel, April 25, 2005 -- Alvarion Ltd. (NASDAQ:ALVR), the world's
leading provider of wireless broadband solutions and specialized mobile
networks, today announced that Microcom, the leading Internet Wireless Access
services provider in the Democratic Republic of Congo, has ordered a large-scale
BreezeMAX(TM) 3500 system to be deployed in the country in the coming year. When
this first WiMAX-ready network in Central Africa goes live, corporate and
residential users in the city of Kinshasa will receive high-speed data services.
Microcom previously deployed Alvarion's BreezeACCESS(TM) II networks.

"Wireless broadband is the most cost effective means to provide high-speed data
to our customers in the city of Kinshasa, a city of approximately 8 million
inhabitants with little wired infrastructure. Our selection of Alvarion as the
preferred vendor was easy due to our positive past experience with the company
and their equipment," said Mr. Leon NTALE, President of Microcom.

"Our decision was finalized to expand with WiMAX to offer our customers wider
coverage, higher data speeds for Internet access and VoIP, and other services
which were not possible with our previous network. Our first deployments will be
in the areas where connectivity was proved to be extremely difficult due to the
non-line-of-sight conditions. With Alvarion's BreezeMAX(TM) 3500, we believe
that Microcom will be in a position to easily expand its service offering in DRC
and quickly increase capacity for its customers," Mr. NTALE added.

BreezeMAX(TM) is an OFDM platform with advanced non-line-of-sight (NLOS)
functionality designed for operators to offer broadband IP-based data and voice
services, allowing for the easy, cost-effective transition to WiMAX. Its
carrier-class design supports broadband speeds and quality of service (QoS) to
enable carriers to offer multi-services to thousands of subscribers in a single
cell. BreezeMAX networks are already installed in more than 30 countries
worldwide. "Microcom's decision to go with our BreezeMAX(TM) network reflects
Alvarion's strategy that WiMAX wireless broadband represents the best economic
alternative to traditional wired access, especially for areas with little
existing telecommunications infrastructure," said Mr. Tzvika Friedman, President
and COO of Alvarion. "Microcom is another customer in a series of service
providers that have jumped at the opportunities offered by a commercial
deployment of our WiMAX-ready BreezeMAX. We are pleased to serve the increasing
demand to provide data connectivity around the world."
