                                                  FOR IMMEDIATE RELEASE

             Alvarion Announces Preliminary Second Quarter Results;
                    Revenue Expected to be $46 to $47 Million

               Revised revenue range relates to project delays and
                 slower-than-expected pace of some installations

TEL-AVIV, Israel - July 5, 2005 -- Alvarion Ltd. (Nasdaq: ALVR), the world's
leading provider of wireless broadband solutions and specialized mobile networks
indicated that, when results for the second quarter are announced on August 3rd,
revenue is expected to be between $46 and $47 million. The Company indicated
that, at this revenue range, EPS for the quarter is expected to be a loss per
basic share of $0.06 to $0.08 on a GAAP basis, and a loss per basic share of
$0.04 to $0.06 on a non-GAAP basis, which excludes amortization of intangibles
and of deferred stock-based compensation, and non-recurring charges, totaling
about $1 million.

The shortfall was caused by unrelated customer-specific issues in non-WiMAX
areas:
o     Delays in a few projects as a result of customers' internal reasons such
      as budget adjustments
o     Slower-than-expected installations, mainly of certain compact cellular
      projects, which did not allow us to recognize the revenue from equipment
      already shipped.

Management's original Q2 guidance already took into account both some minor
disruption from the transition to WiMAX and the probability that its largest
customer in 2004 would account for a very low amount of Q2 revenue compared to
its revenue contribution in the past several quarters.

"It became clear that these customer-specific delays would affect our Q2 revenue
in the final days of the quarter," said Zvi Slonimsky, CEO of Alvarion.
"Interest in WiMAX continues to gain momentum and, although it was a relatively
small portion of the total, revenue from our BreezeMAX(TM) product was in line
with our plan in Q2."

"We continue to expect the second half of 2005 to be better than the first half.
In light of the Q2 shortfall, we will have to re-evaluate the achievability of
our target for the year, and we will give guidance for Q3 and update the overall
outlook on August 3, after we have had an opportunity to go through our normal
quarterly analysis process," concluded Mr. Slonimsky.
