Why Use P25?

P25 LogoProject 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 TIA and Personal Private Radio Standards Committee.

The Project 25 standard is established with a twenty year history within the public safety community, and was established in October 1989. As the P25 standard exists in the public domain, any manufacturer can produce a P25 compatible radio product.

Public Safety Agencies around the world depend on Project 25 for their mission critical communications. The P25 standard is also adopted by many industries such as utilities, airports, transit, petroleum and chemical companies that rely on mission critical communications and interoperability with public safety agencies in an emergency.


There a number of significant benefits to using a P25 digital solution including;

  • Communication with legacy radios in analogue or digital mode
  • Interoperability with other systems
  • Encryption for security
  • No degradation of coverage
  • Highly scalable

The P25 standard and the European TETRA protocol are often compared. Both are popular, however the major difference between them is that the focus of P25 is on coverage rather than capacity.

Project 25 supports a variety of system configurations including direct mode, repeated, single site, multi-site, voting, multicast, and simulcast operation. This flexibility is available for both conventional and trunked applications. Project 25 offers high power operation allowing large geographic areas to be covered with fewer transmitter sites, which provides economical benefits over other systems.
