WIRELESS DATA SYSTEM PUTS PHILADELPHIA POLICE
ON-LINE

Bell Atlantic NYNEX Mobile and PRC Public Sector, Inc.
to Aid Police

PHILADELPHIA -- Bell Atlantic NYNEX Mobile, PRC Public
Sector, Inc.,
and the Philadelphia Police Department have joined forces to equip
more than 70 police cruisers with new wireless mobile data technology.

Based on a technology known as Cellular Digital Packet Data (CDPD),
Bell Atlantic NYNEX Mobile has installed 70 laptop computers into
Philadelphia Police vehicles, while 7 are being used in the police
training facility. The computers, coupled with software provided by
PRC Public Sector, Inc., will provide officers on the street with
instant wireless access to the information they need to make critical
decisions that will enhance the safety of the community as well as
that of the police officer.

"Bell Atlantic NYNEX Mobile has given us a tool which allows us to
deliver more effective law enforcement while making the most efficient
use of our officers' time," said Philadelphia Police Commissioner
Richard Neal. "Area residents will be the direct beneficiaries of
this new technology. Our officers will spend less time doing
paperwork and more time in the community."

Bell Atlantic NYNEX Mobile regional vice president Bob Stott said his
company is pleased to be working with the Philadelphia Police
Department and is looking forward to working with other police
departments interested in the benefits of wireless data technology.

"Because our wireless data service, known as Bell Atlantic®
AirBridge® Packet service, uses our existing cellular network, we are
able to provide police departments with a much more reliable and
affordable alternative to traditional radio transmission," said
Stott.
"There's no need to construct additional radio towers or to worry
about network maintenance or upgrades. Bell Atlantic NYNEX Mobile
takes full responsibility for maintaining and upgrading the system."

The new system will give officers access to reliable, timely
information before they approach a vehicle, house or suspect, allowing
them to accurately assess potentially dangerous situations.

The software that will allow officers to connect to national, state,
and federal data bases, police computers, the National Crime
Information Computer (NCIC), and the Bureau of Motor Vehicles is being
provided by PRC Public Sector, Inc., based in Reston, Virginia.

"This software package saves precious time by only requiring police
officers to make a single entry on their mobile data terminals versus
what may now require a number of inquiries through the police
dispatcher," said PRC Public Sector President Thomas C. Halverstadt.

In addition to saving time, the mobile data terminals will increase
the security of police department communications. Messages carried by
CDPD are "encrypted" or scrambled to prevent unauthorized
reception.

The Philadelphia Police Department may eventually equip more than
1,000 vehicles with CDPD capabilities.
