Trunking is a radio communication technique that makes communication easy, cost effective and more efficient; unlike traditional radio communication systems e.g. comreps (Community Repeaters), where different users have been operating on separate radio frequencies or radio channels. A Challenge with traditional radio systems is that the number of channels is often exceeded, whilst radio trunking smartly controls and guides the users toward a free channel, thereby reducing waiting times.
Trunking is defined as the automatic and dynamic allocation of a small number of radio channels among a large number of radio users in the most efficient way. Trunking therefor permits a large number of users to share a relatively small number of communication channels. Channel assignment is automatic and completely transparent to the individual users. Finding a free channel is therefore not the user obligation as the system does it automatically and in the shortest possible time.
