announced today the signing of a joint marketing agreement to address the data needs of the rapidly deregulating electric, gas, and water industries. Using Bell Atlantic Mobile's AirBridge® Cellular Digital Packet Data (CDPD) network, Comverge Technologies hardware and software solutions offers utility companies automated meter reading, home automation, environmental monitoring, energy management, and distributed generation monitoring services.

Frank Magnotti, President of Comverge Technologies states, "I'm truly excited to expand our relationship with Bell Atlantic Mobile. Bell Atlantic Mobile's coverage in the major population centers throughout the Northeast make them a great partner for us and energy service and distributed generation companies.

Bob Hirsh, Director of Wireless Data Distribution for Bell Atlantic Mobile states, "Meter reading and energy management are perfect applications for our AirBridge® CDPD service. Comverge Technologies has successfully demonstrated these applications on our network. Comverge's hardware and software, combined with our CDPD service, provide a cost effective way to offer these kinds of services to customers."

Magnotti added, "I'm impressed with the capabilities of the CDPD network. Their intelligent network has made system integration quick. We can rely on Bell Atlantic Mobile to continue to upgrade its capabilities. We would not have found this with private proprietary networks."
