               ALLEN TELECOM UPDATES SECOND QUARTER 2002 GUIDANCE
               --------------------------------------------------

         BEACHWOOD, OHIO, June 11, 2002 - At a Bear Stearns Technology
Conference with analysts and investors today in New York City, Allen Telecom
Inc. (ALN: NYSE) commented on its second quarter 2002 financial performance. In
its first quarter conference call in April 2002, the Company had indicated that
second quarter 2002 sales in non-Geolocation product lines were anticipated to
be higher than first quarter 2002 levels, but that Geolocation sales would be
lower in the second quarter due to the transition between the conclusion of the
Verizon contract and the startup of deployment with AT&T Wireless. During the
conference earlier today, the Company stated that April and May sales were
developing as expected, and total sales for the second quarter are now expected
to increase modestly from the first quarter.

         The Company also affirmed its earnings outlook for the second quarter
2002 from the April conference call when it had indicated that earnings were
expected to be flat to down slightly as compared to the first quarter 2002.

         The Company has continued its strong emphasis on cash flow and
estimates that it will generate approximately $10M in cash during the second
quarter and enhance the Company's liquidity.
