C4 Systems Demos ISSI Interoperability at Lab (1/9)
General Dynamics C4 Systems said it is the first company to demonstrate the new standard to allow two-way radio users to communicate using different manufacturers' radio systems operating on different networks. The demonstration was held in early December at the General Dynamics homeland-security system development laboratory in Scottsdale, Ariz. Radio system manufacturers M/A-COM and EADS Secure Networks worked with General Dynamics to achieve the milestone. The demonstration used the Project 25 (P25) inter-RF sub-system interface (ISSI) standard to enable the two systems to connect within the network infrastructure rather than over-the-air between the radios. The standard was developed to achieve better communication among public-safety users. In this first known demonstration of its kind, General Dynamics, EADS Secure Networks, and M/A-COM collaborated for several months to meet the interoperability standard. Interoperability testing will continue at the lab as more features become standardized and more radio manufacturers become ISSI-compliant, General Dynamics said.
