P25 public safety radio coverage
P25 is the North American public safety standard, and its installed base is growing as agencies move to broadband. This page explains the standard, the bands it uses, and how our repeaters bring P25 into buildings and tunnels.

What P25 radio is
P25 (Project 25) is the family of standards used by public safety agencies in North America and increasingly elsewhere. It covers narrowband FDMA (12.5 kHz), wideband FDMA (6.25 kHz) and broadband (LTE and 5G NR) in one family, which lets an agency migrate without replacing its terminals. Our P25 units are also compatible with TETRA, TetraPol, DMR and analog FM on the radio path, so one installation can carry more than one standard.
- Operating bands
- 700 MHz / 800 MHz (806.6–810.6)
- Power
- +37 dBm channel-selective · +40 dBm fibre-coupled
- Channel count
- 16 channels (700 MHz channel-selective)
- Also compatible with
- TETRA, TETRAPOL, DMR, analog FM
How we extend P25 coverage
Two product families: a 700 MHz channel-selective unit for in-building and below-grade fill, and a +40 dBm fibre-coupled system (off-air BDA, master and remote units) for large sites where RF donation is not practical. Both are listed in the model list with their datasheets.

Common questions
Is P25 the same as TETRA?
No. They are different standards with different channel plans and different network timing, so a repeater designed for one is not automatically right for the other. Our datasheets list the compatible standards explicitly.
Does P25 need a licence, and does that change the repeater?
Yes, agencies hold licensed channels. That is why channel-selective units matter: the unit passes only your licensed channels, and the channel plan is set per project.
Can we migrate to P25-LTE without new hardware?
In many cases yes — the radio path and the installation are shared. Tell us your target end state and we will confirm what can be reused.
