What is GCM 8000?

The GCM 8000 compares multiple received message streams on a frame-by-frame basis. The best frames are compiled into a new, high-quality message that will be transmitted for others to hear.

What does a motorola comparator do?

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.

What is a radio voter?

Receiver voter / receiver voting selector / voting panel / voter: The equipment, usually rack mounted, that interprets the audio from several outlying receivers (usually connected by leased phone lines) and picks the best quieting signal on the fly and routes it to a single output.

How does a trunked radio system work?

A trunked radio system is a two-way radio system that uses a control channel to automatically assign frequency channels to groups of user radios. Instead of assigning a radio channel to one particular user group at a time, users are instead assigned to a logical grouping, a ‘talkgroup’.

What is a multicast radio system?

Multicast systems are similar to simulcast systems with exception of the radio channels transmitted. For example, when two users occupy a channel at one site, that channel normally cannot be used at the same time by other users at different sites.

How does multicast radio work?

Multicast uses network infrastructure efficiently by requiring the source to send a packet only once, even if it needs to be delivered to a large number of receivers. The nodes in the network take care of replicating the packet to reach multiple receivers only when necessary.

How does the GCM 8000 comparator system work?

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.

How is the GCM 8000 used in Project 25?

Results cannot be populated at this time. 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.

Which is trunking system does the GCM 8000 support?

The GCM 8000 supports P25 digital conventional and P25 trunking systems. Provides superior talk-in performance and system coverage in voting and simulcast network topologies. Employs dynamic frame-by-frame voting and combining to ensure the best audio quality is constantly transmitted for other users to hear.

Is the GGM 8000 a mission critical gateway?

Government and industrial organizations rely on ASTRO 25 systems for mission critical communications and to meet their demanding needs, the GGM 8000 gateway is built to deliver performance, capacity and security above and beyond the capabilities of traditional networking hardware.
