Contents

A trunking radio system differs from a conventional radio system in the way it shares channels between radios

• 1 channel to one or more groups of user

• Employs no logic in call handling

• Usually 1 call to 1 channel

(2 to 1 with MOTOTRBO digital)

• A trunking system shares a pool of channels

for a large number of users (talkgroups)

• Automatically assigns available channel to

requesting user

• Lowers probability that calls will be blocked

because an open channel will be found

easier

• Allows fewer channels to support larger

amounts of users
