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. Be sure to read about the Technology Benefits of P25.

Why P25?

Project 25 enables successful fulfillment of these factors so critical to public safety operations and use of two-way radio communications in the field.

Enables ease of operation for more rapid adoption and training.

Enables planned migration of systems and equipment from old to new.

Enables Interoperability essential to multiple jurisdiction and joint operations.

Enables multiple vendors sourcing for cost effective and competitive procurements with no compromise in system capabilities.

Technology Benefits

From the beginning, P25 has targeted four primary objectives:

  • Allow effective, efficient, and reliable intra-agency and inter-agency communications
    … so organizations can easily implement interoperable and seamless joint communication in both routine and emergency circumstances.
  • Ensure competition in system life cycle procurements
    … so agencies can choose from multiple vendors and products, ultimately saving money and gaining the freedom to select from the widest range of equipment and features.
  • Provide user-friendly equipment
    … so users can take full advantage of their radios’ lifesaving capabilities on the job – even under adverse conditions – with minimal training.
  • Improve radio spectrum efficiency
    … so networks will have enough capacity to handle calls and allow room for growth, even in areas where the spectrum is crowded and it’s difficult for agencies to obtain licenses for additional radio frequencies.
