AT&T Case Study
AT&T is one of the world's premier voice and data communications
companies, serving consumers, businesses, and governments
worldwide. The company operates the world's largest, most
sophisticated communications network and has one of the largest
digital wireless networks in North America.
The challenge was to seamlessly manage end-to-end deployment
of new cell site builds and supported transition from a 2.5G
network to a 3G high-speed data network for AT&T Wireless
Services (AWS).
Underway since 1999, the project has involved migration of
the network from TDMA through GSM, GPRS, and EDGE capabilities,
into wideband UMTS services. WirelessWerks also supported
the AWS E911 Phase II compliance initiative through the installation
of TDOA and AOA technologies.
AWS chose WirelessWerks USA because of their people - WirelessWerks
had the right people in the right location with the right skills and
had delivered results on previous projects. WirelessWerks employees work
in a no excuses environment and strive to make customers’ lives easier
as a result of their involvement.
In 1999, AWS chose WirelessWerks to help manage the capacity
and coverage needs of their network with the deployment of
TDMA sites.
In 2001, WirelessWerks was selected to help manage the transformation
of the network from a TDMA network to a 2.5G GSM/GPRS/EDGE
network, capable of handling high-speed data. This upgrade
and expansion involved the overlay of 30,000 existing sites
with both 1900 and 850 GSM technology.
In 2003, WirelessWerks was asked to provide further enhancements
with the implementation of the full 3G UMTS capability in
four key cities, as well as support capacity and growth requirements
in the existing network. WirelessWerks provided network RF
planning, site build, civil design, transport testing and
acceptance (including microwave design, installation and testing),
and construction management. WirelessWerks continues to support
the AWS (now Cingular) growth and capacity needs.
