GCM 8000 Comparator
The GCM 8000 Comparator is used in Project 25 (P25) conventional or P25 trunking voting and simulcast network topologies to increase the talk-in coverage of a radio in the field.
The comparator works by picking up the audio from multiple sites and performing a frame-by-frame analysis to identify and combine the highest quality audio package for transmission.
The GCM 8000 supports P25 digital conventional and P25 trunking systems.
