P25 Interoperable LMR
The Project 25 suite of standards involves digital Land Mobile Radio (LMR) services for federal, state, and local public safety organizations and agencies. P25 is applicable to LMR equipment authorized or licensed, in the United States, under National Telecommunications and Information Administration (NTIA) or Federal Communications Commission (FCC) rules and regulations.
EFJohnson Technologies provides P25 compliant two-way radios and trunked and conventional communication systems for law enforcement, fire fighters, EMS, and the military.

Our products have been in compliance with Federal interoperability standards for more than a decade, and have passed numerous interoperability tests on government facilities, in independent laboratories, and even at the headquarters of our biggest competitor.
We have been a key participant in successful Project 25 Inter RF-Sub-system Interface (ISSI) Multi-Vendor Interoperability Demonstrations at the 2007 and 2008 APCO International conferences. ISSI is a significant milestone in wireline interoperability. The P25 ISSI interface will enable two or more disparate, trunked, P25 networks to be connected at the network layer. It will provide roaming across multiple networks while enabling dispatchers to monitor operations and communicate with users outside of their coverage areas.
