P25 Two-Way Radio Systems

Evolution Technologies P25 Two-Way Radio Systems are the safest and most secure form of Two-Way Radio.

What is P25?
P25 two-way radio systems was developed as a standard for digital radio communications with the primary use for public law enforcement and safety agencies to enable them to communicate with other agencies and response teams in emergencies.

The P25 standard is in the public domain meaning any manufacturer can create a compatible product and its able to operate in two modes:

Conventional

– Radio channels selected by the user
– Channel access instantaneous
– No control channel needed
– Suitable for smaller groups of users
– Switching not needed
– Digital control signaling inherent

 

Trunked

– Radio channels assigned to their user automatically
– Channel access time varies with technology and other factors (typically measured in hundreds of milliseconds)
– Control channel used in all P25 trunked applications
– Better for larger (~300+) organisations
– Core switching essential for operation
– Digital control signaling inherent
