What isTrunking?

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
• 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)
