Although a trunked radio system is so common that you can see them in everyday life. However, many people who do not understand them well might ask “What is a trunked radio system?”
The trunked radio system can be understood as a trunked two way radio. This system integrates using the control channel to assign the channel frequency to the device automatically. Therefore, they are often used among talk groups to connect users.

All About Trunked Radio System
Trunked radio systems are quite common devices these days. As mentioned above, the trunked radio system is an integrated control channel device, so it can automatically connect user groups by assigning frequency channels.
The trunked radio systems typically include a few essentials: a radio, a radio transceiver, a microprocessor, and a control channel.
As can be seen, radio trunking is quite complicated because they are highly automatic. However, this system receives a lot of people’s favor because of the benefits it brings.
The use of a trunked radio system helps users not to interfere too much in its operation. At the same time, this system also allows many people in a talk group to work together.
A time-saver when using this system is that if there are people free at the same time, they can chat with each other. Therefore, conversations in talk groups can be done at the same time with unrelated issues.
The nature of the system
In essence, you can understand that the trunked radio system mentioned here is essentially a network system with packet switching. Therefore, users in the talk group need to keep the radio to send data to the shared computer when using it.
This computer works exclusively in a certain group and is often referred to by the name control channel.
Having a control channel makes it possible for digital signals to be sent to the general monitoring radios of the talk group. Then, through the monitoring system, the radios that receive the request can switch to a specific frequency to perform the service.
Finally, the radio will return to the original frequency at the control channel for further use when the conversation is over.
A general description of the use of this system is that two people who are far away from each other use trunked two-way radios for mobile communication.
The automatic and planned operation of radios helps users in a talk group share information on the same specific frequency. Not all members can hear the news that only a few people have at the same specified frequency level.
Fleet maps and IDs in the trunked radio system
As you read through the above information, you may be a little confused about Fleet maps and IDs. Don’t worry, and we will explain more about this.
Each system has its settings, of course, always based on some requirements and the nature of the problem to be solved.
For example, an agency needs to run, and a plan is a must. After that, weaker groups will gradually add to increase the strength of the agency.
Similarly, in this system, each person in the talk group will receive a Fleet map of the general group according to the user’s needs. Each different talk group will have its ID on the system.
This makes it easy for the controller to recognize and add appropriate transmission lines to the receiver’s walkie-talkie. The talk group then performs separate tasks.
If you already know about common radio systems, you can easily notice the difference between them.
While a conventional radio system gives each user a separate frequency channel in a talk group, a radio trunking system allows users in a talk group to use the same set of tracks.
Advantages of Radio Trunking
The use of radio trunking brings many practical benefits to users. As can be seen, the intermediate station is often set up based on making full use of the gaps that can be found in a system of talk group units.
- Multiple users: Of course, not all users need to access the channel at a given time, so discrete radio channels are not necessary. At the same time, using a radio trunking system also helps increase the number of users in the talk group.
- Channel switch: When using a trunked radio system, you may find that they are no different from regular radio stations. This is true because they still have only 1 channel switch designed to help users choose the type of channel they want to connect.
But if you take a closer look at these channel switches, you can see that they don’t work with conventional frequency switching. This button refers to a software program associated with the talk group and transmitted from the control channel. Therefore, using a channel switch will help users connect with another person in the talk group and bring them into the conversation.
- Flexibility: Another significant advantage of this system is its flexibility. You can completely use the same type of radio for many groups of people by changing the preset software in the radio.
Several Types of Trunked Radio Systems
The widespread use of trunked radio systems can be seen because of the convenience and positive effects they bring.
Trunked radio systems are often used for agencies, police departments, and some necessary services in daily life. Two common types of trunked radio systems are trunking police scanners and trunking scanners.
Frequently Asked Questions
Besides the question about the trunked radio system, its issues also receive a lot of attention from people. Many people also often ask questions about related topics such as:
What does trunking mean?
In simple terms, trunking is commonly used in systems that transmit information or share data for many users to access. Users can access the network based on a transmission line or frequency to enter the desired network.
What is the better choice between digital trunking and trunking?
The biggest difference between the two is their size. If digital trunking can be understood as a modulation system with signals carrying voice and related information to be transmitted, trunking is a system of sharing frequencies through high traffic.
How does a trunking system scan?
A trunking scanner works similarly to a trunked radio system, which means that every user is in the queue before connecting. They will receive the assignment with a suitable channel next.
Will Trunking police scanners become obsolete?
It can be said that Trunking police scanners are very unlikely to become obsolete. Although many people use apps or scanners that are already on their phones to commit crimes, PDs are also gradually becoming more modern encryption.
The encryption currently used is AES. At the same time, manufacturing companies do not provide exclusive licenses for their scanning systems.
