           ALVARION TO ACQUIRE interWAVE COMMUNICATIONS INTERNATIONAL

Mountain View, CA and Tel-Aviv, Israel, July 27, 2004 - Alvarion Ltd. (NASDAQ:
ALVR) and interWAVE(R) Communications International, Ltd. (NASDAQ: IWAV) today
announced that they have entered into a definitive agreement which calls for
Alvarion to acquire interWAVE for $5.75 per share in an all-cash transaction
valued at approximately $56 million. interWAVE is a leading provider of compact
mobile GSM and CDMA network equipment and services, primarily aimed at low
density markets in developing regions, as well as specialty vertical
applications. Alvarion is the worldwide leader in wireless broadband solutions
and is focused on leading the market to widespread adoption of standards-based
products through its prominent work in the WiMAX Forum(TM).

We are excited about this transaction for several reasons," said Zvi Slonimsky,
CEO of Alvarion. "First, it immediately provides an outstanding cost-effective
fixed and mobile cellular solution to complement our eMGW residential voice and
data solution serving regions of the world where wireline infrastructure is
missing or inadequate. The addition of interWAVE expands our served market to
include a rapidly growing segment of the mobile equipment market, broadens our
customer base with additional top-tier operators, and leverages both our strong
channel relationships and our global sales and customer support capabilities.

"Second, interWAVE's technical expertise in cellular systems design and
extensive experience in providing complete mobile networks will accelerate the
development of our


                                       4



next generation portable/mobile WiMAX offering. We are well-positioned to
continue leading this last-mile revolution as WiMAX moves from fixed-only
solutions to include both fixed and mobile capabilities."

interWAVE provides economical and distributed cellular networks that scale from
a few thousand to 100,000 subscribers, enabling operators to minimize capital
expenditures while accelerating revenue generation. The company's solutions are
deployed in over 50 countries by more than 100 operators, mainly local and
regional cellular operators. Headquartered in Mountain View, CA, interWAVE's
trailing 12-month revenue for the period ended March 31, 2004 (unaudited) was
$39.4 million.

interWAVE is a global company. Its primary activities such as research and
development, operations, sales and marketing take place in the United States,
providing a Silicon Valley presence, with engineering facilities in China and
Ireland and additional sales and marketing facilities in other locations around
the world.

"We believe that Alvarion's market recognition as a leader, its financial
strength and global presence will support rapid growth of compact mobile
networks and enable ongoing support and the ability to handle large scale,
country-wide expansions. We consider interWAVE as one of Alvarion's growth
engines for the future," Mr. Slonimsky added.

Erwin Leichtle, CEO of interWAVE, will join Alvarion's management team and will
lead the mobile unit. Mr. Leichtle is a telecom veteran with more than 30 years
experience in senior management positions, primarily at Ericsson, in various
international markets and the United States.

"The combined strengths of Alvarion and interWAVE will be a tremendous benefit
to wireless broadband access, and will create large new revenue opportunities
for Alvarion," added Mr. Leichtle, "We believe that Alvarion's global reach and
strong balance sheet will accelerate the growth of our advanced GSM and CDMA
2000 1XRTT compact network products. We are excited about the opportunity to
contribute to the next generation of portable/mobile WiMAX solutions through our
years of experience with mobile networks and our mobility management
technology."

The transaction will be effected through the amalgamation of interWAVE, and a
wholly owned subsidiary of Alvarion. The transaction is subject to and
contingent upon the approval of interWAVE's stockholders. The boards of
directors of both companies have approved the transaction and interWAVE's board
of directors has unanimously agreed to recommend that the company's stockholders
vote in favor of approving the transaction.

The acquisition is expected to be completed by the end of the third quarter of
2004. Based on this timing, it is expected to have minimal impact on Alvarion's
Q3 earnings, excluding any acquisition-related charges, to be minimally dilutive
in Q4 and Q1 of 2005, and to be accretive beginning in the second quarter of
2005.

                                       5
