Project 25 Technology Information Group


The Project 25 Technology Interest Group (PTIG) has developed a new whitepaper on the benefits of P25 technologies for use in Fire ground operations.  Many improvements to the P25 Standards, the P25 vocoder and the P25 products available make it a good time to revisit P25 as a technology for Fireground use.  A summary of the key points is below.   The complete whitepaper can be found using the following link.

A good time to revisit P25 for use on the Fire ground


Summary Benefits of using P25 mission critical radio equipment for the Fire ground include:

  • Improved P25 performance in background noise. P25 equipment can now achieve 10 to as much as 25 dB improvements in background noise reduction.
  • Tone Signaling – DTMF, Knox and single tone is now supported.
  • Paging – P25 Paging receivers are now available.
  • Improved Coverage – P25 Phase 1 technology is about +7dB better than 25 KHz Analog.
  • Enhanced Signaling – Talking Party ID, Group Calls, Unit-to-Unit Calls, All Calls, Emergency Alerts, Emergency Calls, Call Alerts, Radio Check, Radio Unit Monitoring and others.
  • Location Services – Integrated GPS receivers provide location information.
