Cerulean's Multi-Protocol Server lets public safety agencies simultaneously use different radio networks and data protocols for enhanced mobility.

MARLBOROUGH, Mass.--(BUSINESS WIRE)--April 6, 1998--

Streamlines communications through one server for better

mobility, cost savings, and also provides a migration

path to other radio network infrastructures

Public safety agencies can now pick the most economical radio infrastructure for their needs based on each user's message volume and mobility using Cerulean Technology's Multi-Protocol Server communication system. The multi-protocol feature of the PacketCluster(R) Patrol(TM) and PacketCluster(R) Rescue(TM) wireless mobile information systems lets users on different radio networks communicate via one server.

Departments with limited access to new and existing radio channels can use existing cellular networks to help maximize mobile information systems' capabilities without clogging their wireless networks. Multi-Protocol Server provides an easy and simple migration path from a private radio system to a public wireless network. For example, a department can enable a few patrol cars with cellular digital packet data (CDPD) prior to the entire department converting to the technology. Also, public safety vehicles regularly traveling beyond the conventional radio's range can be equipped with a mobile computer unit configured for CDPD transmission. This keeps the officer or incident commander connected to headquarters for continual access to mission critical information.

PacketCluster Patrol wireless mobile information software gives officers in the field instant access to local, state and national databases through laptop computers. PacketCluster Rescue software, introduced last month, gives firefighters immediate wireless access to mission-critical information for fire suppression. Both applications support sophisticated messaging features that improve agency communications, thereby increasing personnel safety. Multi-Protocol Server enables them to communicate with centralized operations through PacketCluster server software. By supporting data protocols such as Motorola RD-LAP, CDPD, Dataradio DMP, Ericsson EDACS, BellSouth Wireless Data (RAM Mobile Data) Mobitex, and others, Multi-Protocol Server overcomes radio coverage problems associated with police precincts or fire stations located in non-contiguous, or geographically separated areas. Multi-Protocol Server also ensures efficient use of resources and provides an upgrade path for police departments or fire stations that want to gradually shift to a different radio network infrastructure.

The multi-protocol feature of the PacketCluster wireless mobile public safety solution lets users on different radio networks communicate with one another without additional server software. The same PacketCluster server, for example, can be used for public safety agencies whose police departments are using the PacketCluster Patrol solution via private radio (VHF, UHF, 800 MHz) and whose fire departments are using PacketCluster Rescue software on a public wireless radio network, such as CDPD.

"Multi-Protocol Server gives public safety agencies the flexibility to choose which radio networks work best for them. This infrastructure independence opens the door for migration from one radio network to another," said Cerulean Director of Product Marketing John Dorr.

Cost-effective radio infrastructures

Not only does Multi-Protocol Server improve economy and versatility, it also lets agencies decide on the most cost-effective radio infrastructure for each user. For example, some parts of an agency may be using CDPD and others may be using conventional radio for their remote and mobile communications. The Multi-Protocol Server channels all transmissions through a single server, eliminating the need to connect two separate networks with a custom-built interface.

"Information technology has suddenly become an absolute necessity for police officers," said Lt. Mark Rudolph of the Medford, Mass. police department. "Increased, very fast access to information about individuals that police encounter is vital to an officer's and the public's safety."

About PacketCluster Solutions

PacketCluster applications are open, standards-based wireless information software products that provide police officers and firefighters in the field with potentially life-saving information. Police officers can directly access motor vehicle and warrant information within seconds, reducing risk in dangerous situations. Instead of relying on two-way radio calls to busy dispatchers for limited information, officers can tap into a wireless computer network from laptop computers in their cruisers to get complete motor vehicle and warrant information. Also using laptop computers from emergency vehicles, firefighters can access in-house records management systems and retrieve up-to-date building content information, hazardous materials databases, personnel rosters, fire inspection data, hydrant maintenance records and other fire suppression information.

The highly flexible software can be run over all popular public and private networks, including conventional VHF/UHF radio and advanced cellular digital packet data (CDPD) networks. PacketCluster software also improves officer and public safety by enabling real-time silent communication between headquarters and mobile units for quick back-up.

Both applications run on industry-standard Microsoft(TM) operating systems. The PacketCluster server, or message gateway, operates on the Microsoft Windows NT(TM) operating system, while the client software operates on Microsoft Windows 95 and/or Microsoft Windows NT.

An intelligent, client/server application, PacketCluster software truly enables its users with power. Its flexibility to work with other software programs and easily incorporate emerging technologies makes PacketCluster software highly leveragable since it offers a low cost of ownership and a high return on investment.

PacketCluster Patrol won the Cellular Telecommunications Industry Association's 1996 APPY Award for best end-user software.
