FOR IMMEDIATE RELEASE
Thursday, January 11, 2001



          ADAPTIVE BROADBAND(TM) AND WESTERN MULTIPLEX AGREE TO CALL
           OFF MERGER, CITING CURRENT UNFAVORABLE MARKET CONDITIONS


Sunnyvale, CA-ADAPTIVE BROADBAND CORPORATION (Nasdaq National Market: (ADAP)
                                                                       ----
announced that it and Western Multiplex Corporation have agreed to a friendly
unwinding of the companies' merger agreement announced November 13, 2000.

Uncertain Stock Market, Weakness in Fixed Wireless Industry Among Reasons for
Halting Merger

Adaptive Broadband and Western Multiplex have decided to call off their planned
merger. "The fixed wireless industry currently is experiencing weakness in the
U.S., and financing is eroding for emerging carriers. From a stock market point
of view, fixed wireless specifically, and telecommunications stocks, in general,
have really taken a beating, making it very difficult to put a monetary
valuation on this transaction at this time. While we continue to believe in the
strategic merits of a merger with Western Multiplex, prevailing market
conditions do not allow a deal at this time,"commented Adaptive Broadband's
Daniel L. Scharre.

Adaptive Broadband recently lowered revenue expectations for its fiscal year
2001 second quarter ended December 31, 2000, to $8 million from an anticipated
$31 million. The company is currently evaluating its financial model for its new
fiscal year beginning January 1, 2001, especially the potential impact of
customer issues surrounding the Competitive Local Exchange Carriers, the
company's primary U.S. market. Adaptive Broadband is expected to announce
second-quarter results and discuss its current business environment in its press
release and conference call on January 25, 2001. The company is not holding a
conference call prior to the January 25 call.

Management Transition Plan Accelerated at Adaptive Broadband

In view of recent developments, Adaptive Broadband's board of directors has
accelerated a management transition plan. Daniel L. Scharre has been named
president and chief executive officer and joins the board immediately. Frederick
D. Lawrence is retiring immediately from the company rather than in July 2001,
as planned, and has resigned as chairman of Adaptive Broadband's board of
directors. Leslie G. Denend, currently a member of Adaptive Broadband's board of
directors assumes chairmanship of the board. Additionally, Peter J. Maloney,
senior vice president of finance, succeeds Donna S. Birks as chief financial
officer, who has also accelerated her retirement plan. These management changes
are effective immediately.

"Adaptive Broadband was not for sale when approached by Western Multiplex and is
not currently for sale. We will move forward as a viable, stand-alone company,
and believe that our technology leadership position, strong balance sheet and
expanding international opportunities


will allow us to succeed in the fixed wireless market," commented Les Denend,
chairman of the board.
