What is Project 25?
Why are we (the Federal Government) using P25?
Radios that are P25 compliant will allow users from different agencies or areas to communicate directly with each other.
P25 radio standard is backward compatible with standard analog FM equipment.
P25 Standard includes a requirement for protecting digital communications with encryption capability.
Over the Air Re-keying (OTAR)
P25 maximizes spectrum efficiency by narrowing bandwidths.
The RF spectrum is a limited resource used by every county in the world.
Spectrum efficiency frees up more channels for radio system use.
P25 digital signals have greater voice quality over standard analog signals.
Audio is digitally encoded, so background noise typically present in analog systems is removed.
P25 radio systems have signaling capabilities.
Allows a vast array of additional functions and features to be standard in any P25 radio system.
Selective calling, Talk Groups (TGID), NAC, emergency flags, GPS, other data.
