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 two-way radio communication.

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 two-way radio systems are:

♦

No channel monitoring required prior to transmission

♦ Fast system access

♦ Automatic channel selection

♦ Privacy among members of the same group
