Advantages Of Trunking
Trunking allows many users to share a fixed number of communi- cation channels without interfering with one another. Telephone companies for years have used trunking to make the most efficient use of their equipment, and similar trunking methods have been adapted to
A trunked radio system allows a large number of users to share a relatively small number of frequencies. When an operator estab- lishes communication with someone else in the system, the sys- tem automatically assigns a communication path - a repeater and its frequency. Once the conversation has ended, the repeater is freed for other users. Trunking pools all the repeater air time, and this maximizes the amount of air time available to any one mobile unit and minimizes channel congestion.
Some of the key benefits of trunked
♦No channel monitoring required prior to transmission
♦Fast system access
♦Automatic channel selection
♦Privacy among members of the same group
