TRUNKED RADIOS

Trunked Radio Systems

The term trunked radios may be confusing to many people.

However, in the simplest sense, trunked radios operate differently from conventional radios by using the concept "Pooling of Frequencies".

In conventional radios, each frequency is dedicated to one group of users but there are a few problems associated with this.

Firstly, as demand for more groups of users grows, it becomes almost impossible to have enough frequencies to assign to each group of users.

Secondly, the length of a conversation is typically less than 15 seconds. If we monitor the usage on conventional radio systems, the actual usage is less than 5%. What this means is that the precious resource, the frequencies, are not being fully utilized.

To overcome these inherent problems with conventional radios, trunked walkie-talkies were developed.

Instead of dedicating each frequency to a particular group, all the available frequencies are first pooled together. The frequencies or channels are then assigned as and when a user requests to make a call.

The system controller in a trunking system will assign a frequency to the user for the duration of the call, recovers the frequency back once the call ends and then reassigns it to another user who later requests for a call.

In this way, frequencies are utiliaed fully and more users can be supported in the trunked system versus a conventional radio system.
