What is Project 25?

Project 25 (P25) is the standard for the design and manufacture of interoperable digital two-way wireless communications products.  Developed in North America with state, local and federal representatives and Telecommunications Industry Association (TIA) governance, P25 has gained worldwide acceptance for public safety, security, public service, and commercial applications.

The published P25 standards suite is administered by the Telecommunications Industry Association (TIA Mobile and Personal Private Radio Standards Committee TR-8).  Radio equipment that demonstrates compliance with P25 is able to meet a set of minimum requirements to fit the needs of public safety.  The P25 standard was created by, and is intended for, public safety professionals.
