The Arizona Public Safety Communications Commission Statewide Radio System Demonstration Project is piloting a deployment of Motorola's ISSI Gateways on Project 25 Networks between live Project 25 (P25) networks.

The prototype installation culminated many months of multi-agency collaboration and provided "connected coverage" with the Regional Wireless Cooperative in Phoenix and the Yuma Regional Communications System.

"Our job is to magnify Arizona's innovation capacity to build a foundation for the future," said Arizona Governor Janet Napolitano. "The Motorola ISSI gateway trial is an excellent example of driving innovation, which will enable our state with agency interoperability to best protect our residents and visitors."

The primary objective of the state's interoperability project is to provide proof of concept for the "systems of systems" approach to connect existing regional communication systems by providing a statewide interoperability solution. By deploying a 700 MHz RF site for additional coverage on each of the regional networks, the network users achieve expanded coverage and capacity. Connecting two networks with digital microwave and by installing the Motorola prototype ISSI gateways, users on ISSI talkgroups can roam from one network to the other while maintaining connectivity back to their home users and dispatchers.
