        U.S. Wireless Corporation and Cellular Technical Services Company
                 Announce Letter Of Intent To Combine Companies


            San Ramon, CA, March 3, 1998 -- U.S.  Wireless  Corporation  (NASDAQ
Symbol:  USWC) and Cellular  Technical  Services  Company,  Inc. (NASDAQ Symbol:
CTSC)  today  announced  the  signing  of a letter  of  intent  calling  for the
combining of the two companies. The letter of intent provides U.S. Wireless with
the option to acquire or merge with CTSC.  Under either option,  upon completion
of the transaction the shareholders of CTSC and USWC will each own 50 percent of
the shares of the  resulting  company.  The board of directors of the  resulting
company will be  controlled by the  stockholders  of USWC.  The  companies  have
commenced a 45-day due diligence and final  agreement  negotiation  process.  In
connection with the merger, the letter of intent calls for the companies to seek
approximately $15 million in new financing.

            Dr. Oliver Hilsenrath,  President and CEO of U.S. Wireless, said "We
have today an  opportunity  to build a market  leader in the area of value added
cellular  applications and services. We believe the effectiveness of RadioCamera
in  both  metropolitan  and  heavily  built  suburban  environments  is a  major
competitive advantage over other proposed solutions to wireless caller location.
Combining  the  strength  of the  RadioCamera  with  the  widely  deployed  CTSC
Blackbird  fraud  interdiction  system in 40 markets  throughout the nation will
give us an efficient  nationwide rollout platform from which to offer a solution
to wireless carriers for meeting the FCC Emergency 9-1-1 phase II mandate."

            Stephen Katz,  CTSC Chairman and CEO said,  "Our combined  companies
will be able to provide  value-added  products and service to carriers deploying
both analog and digital networks,  including domestic and international cellular
and PCS  providers.  We believe the CTSC  investment  in deploying the Blackbird
fraud interdiction  network in thousands of base stations  throughout the United
States will help springboard the joint team into a position of leadership in the
promising future of mobile wireless information services."
