Motorola & Five Leading Emergency Communications Equipment Manufacturers Demonstrate Project 25 ISSI Interoperability

SCHAUMBURG, IL – The Enterprise Mobility Solutions business of Motorola, Inc. (NYSE: MOT) today announced the successful completion of Project 25 (P25) interoperability testing using Project 25 Inter-RF Subsystem Interface (P25 ISSI) gateways to communicate between a Motorola ASTRO®25 system and P25 systems from five other leading mission critical communications manufacturers, including PlantCML-EADS, Etherstack, Harris Corporation, PowerTrunk and Raytheon Company. These six industry leaders demonstrated another new milestone in interoperability with the successful testing of interoperable communications between the Motorola ISSI.1 Network Gateway and ISSI Gateways from the five other manufacturers.

The testing occurred over the past several weeks using a Motorola ASTRO 25 system connected over an ISSI interface to Project 25 systems from each of the other five leading manufacturers of public safety equipment. Each system was tested separately and successful P25 ISSI wireline interoperability was achieved using each manufacturer’s P25 ISSI gateway.

“This latest testing is another example of P25 manufacturers continuing to work together to advance interoperability for public safety, enabling first responders to communicate in emergency situations,” said Bob Schassler, senior vice president, Motorola Worldwide Radio Solutions. “Motorola supports the Project 25 standard and we are dedicated to enhancing interoperability through the ISSI interface in the public safety environment. This testing highlights our commitment to working with other P25 manufacturers to provide our customers with the confidence that the ISSI standard will allow multiple P25 systems to interoperate to support emergency communications for all public safety agencies.”

The interoperability testing using ISSI gateways marks the fifth major multi-manufacturer P25 interoperability event in the past nine months. The previous four events hosted by various manufacturers tested the P25 Phase 1 CAI to the formal U.S. Department of Homeland Security P25 Compliance Assessment Program (CAP).

“The latest tests demonstrated that the ISSI.1 Network Gateway is an easy and cost-effective way to connect P25 systems and implement end-to-end digital interconnectivity to meet the needs of P25 system users who need to interoperate,” Schassler added.

“Motorola will continue to work with P25 manufacturers and the user community in 2010 and beyond to advance interoperability for first responders.”
