P25 radio

What P25 is

Project 25 is the digital radio standard most US public safety agencies use. It was designed so radios from different manufacturers work together, and so neighboring agencies can talk to each other during an incident.

Conventional P25

A conventional P25 system works like a traditional repeater system, with each channel assigned to a group, but with digital audio, unit IDs and optional encryption. It is often the right choice for a single agency, a smaller county or a fire company. Conventional P25 repeaters can also run analog, so you can switch over a few radios at a time.

Trunked P25

A trunked system shares a pool of channels among many talkgroups and agencies, with a controller assigning a channel for each call. Phase 1 carries one conversation per 12.5 kHz channel. Phase 2 carries two on the same channel, doubling capacity on trunked systems.

What P25 provides

• Interoperability with neighboring agencies and county systems
• Optional encryption (AES-256, DES-OFB or ADP) with key management
• Emergency button, unit ID and radio check
• Talkgroups organized by agency and function
• Works in VHF, UHF, 700 MHz and 800 MHz

Who uses it

Police, fire and EMS agencies, 911 centers, county and municipal governments, and the public works, school and transit fleets that share their systems.
