Bell Atlantic NYNEX Mobile And Cerulean Technology Sign Joint Marketing Agreement

BEDMINSTER, N.J. -- Bell Atlantic NYNEX Mobile and Cerulean Technology, Inc., today announced a joint marketing agreement to provide police officers on patrol with wireless access to motor vehicle and driver information. This integrated solution will help officers track down stolen vehicles and drivers with criminal warrants, and more effectively enforce motor vehicle and insurance laws. The system also provides police departments with Computer Aided Dispatch (CAD) and Automatic Vehicle Location (AVL).

Running over Bell Atlantic NYNEX Mobile's AirBridge(R) Packet CDPD network, Cerulean's PacketCluster Patrol software enables police officers to directly access local, state and national law enforcement databases within seconds from laptop computers in their cars to retrieve complete motor vehicle records and criminal warrant information. Because CDPD technology runs over the cellular network, officers can access the information they need even if they cross county and state boundaries. In contrast, traditional radio transmissions could limit officers' access to information.

Unlike the traditional police radio transmissions, information running over the AirBridge CDPD system to the PacketCluster Patrol system is secure because both systems use encryption. This enables officers to communicate "silently" with each other and with police headquarters via electronic messages, preventing criminals with police scanners from eavesdropping on the communications.

"Our partnership with Cerulean allows us to offer our public safety customers the benefit of a total solution," said Mike Franklin, director of wireless data marketing for Bell Atlantic NYNEX Mobile. "Both companies benefit from leveraging each other's sales forces and expertise. This is a natural fit, which we believe will lead to future offerings between our two companies."

"By combining PacketCluster Patrol with AirBridge, we can arm police officers with 21st century technology," said Robert P. Badavas, president and CEO of Marlborough, Mass.-based Cerulean Technology. "The integrated solution will also provide officers with the driver and motor vehicle information they need to do their jobs efficiently."

The two companies have provided their integrated solution to several law enforcement agencies, including the Bridgewater and Somerville, N.J., and Jefferson Borough, Penn. Police Departments.
