Boston,  Massachusetts - July 27, 2000 - American Tower Corporation (ATC) (NYSE:
AMT) today  announced it has been awarded a contract by AT&T Wireless  Services,
Inc.  (AWS)  (NYSE:  AWE) to provide  turnkey  services  for its fixed  wireless
Digital  Broadband  network  deployment  in key  markets  throughout  the United
States.  The AT&T  Digital  Broadband  network  will  allow AT&T to offer to its
customers  a  bundled  package  of  digital  communications   services  such  as
high-speed  internet  access and  digital  phone  services.  American  Tower has
already begun work in several  markets and has been given notice to proceed with
network  deployment on  approximately  1,500 sites covering  multiple markets in
each of its five geographic  regions.  Deployment for these sites is expected to
be completed by the end of 2001. Under the agreement,  additional markets may be
added over the next two years.

Under the base station  implementation  agreement,  American  Tower will perform
turnkey  services work on  co-location  sites,  including RF  engineering,  site
acquisition,   zoning,  program  management,   construction,   installation  and
components.  In markets where  American  Tower is providing  services  under the
agreement and where co-location  opportunities  are not present,  American Tower
will have the exclusive right to provide build-to-suit services. It is currently
estimated that between  co-location  and  build-to-suit  there may be over 2,300
sites included in this contract over the next two years.

Additionally,  American  Tower  announced  that Jeff Ebihara has been named Vice
President-Business  Development  and will be responsible  for all aspects of the

Prior to joining  ATC,  Jeff was  employed by AT&T  Wireless  Services  where he
directed all system  development  operations for AT&T Wireless in the Southeast.
He also led all national digital broadband site development initiatives for AT&T
Wireless, including co-location, bulk siting, and build-to-suit strategies.
