Trunked Radio System Explained

This is an example of statistical multiplexing.

Trunked radio system explained.

A trunked radio system is a computer controlled network that automatically connects users to available radio channels when they need them. When a user say an officer or sergeant in the field wants to send a message the system assigns them to an available channel decreasing the likelihood that they ll have to wait for a free channel to. There are many different implementations of trunked business and public safety radio using different trunking. When a trunked radio user wishes.

Trunked radio systems centrally manage a pool of channels and intelligently switch users to whatever channel is open at a given time. Trunked radio might be better called computer controlled or computer aided radio. A trunked radio system is a digital two way radio system that uses a digital control channel to automatically assign frequency channels to groups of users. Trunking uses channels much more effectively than conventional systems where a channel is required for each group.

Trunked radio systems in depth. In the basic radio awareness course we introduced the basic principles of trunking. These systems typically have access to. A trunked radio system is a specialized repeater system with one or more towers and multiple frequencies which allows channelized semi private conversations between many more groups of users than it actually has allocated rf channels.

This is often a difficult concept for scanner enthusiasts to understand as trunking represents a paradigm shift in design of the system. Trunked radio system analog trunked radio is going to be obsolete since digital trunked radio offers better functions and features in terms of voice quality security spectrum efficiency and cost. But as soon as the number of groups or the number of users working on a system increases trunking may be a better option. All trunked radios operate in a similar manner although the type of trunking technology used by each type of trunked radio system differs greatly.

Project 25 p25 or apco 25 is a suite of standards for digital mobile radio communications designed for use by public safety organizations in north america p25 radios are a direct replacement for analog uhf typically fm radios but add the ability to transfer data as well as voice allowing for more natural implementations of encryption and text messaging. In a traditional half duplex land mobile radio system a group of users a talkgroup with portable two way radios communicate over a single shared radio channel with one user at a time talking. In the trunked radio environment each agency is assigned one or more talkgroups that the agency s communications will use. If they know the groups that will communicate together a conventional system is a good choice.
