What is digital trunked radio system
A digital 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.
In traditional half-duplex two way radio system, a group of users with portable two-way radios communicate over a single shared radio channel, at a time talking, only one user is allowed speaking. This kind traditional systems typically have access to multiple channels, up to 40 - 60channels, multiple groups in the same area can communicate. In a unontrunked system, channel selection is done manually; before use the group, you must decide on which channel to use, and manually switch all the radios to that channel. This is an inefficient use of scarce radio channel resources, because the user group must have exclusive use of their channel regardless of how little transmission they are doing. There is also nothing to prevent multiple groups in the same area from choosing the same channel, causing conflicts. A trunked radio system is an advanced alternative,most of the important, the channel selection process is done automatically.

Digital trunked radio system primary purpose is efficiency; many people can carry many conversations over only a few distinct frequencies. Trunking is used by many government entities to provide two-way communication for fire departments, police and other municipal services, who all share spectrum allocated to a city, county, or other entity.
Then what is the difference between digital trunked radio system and tradiontal two way radio system?
Digital trunked radio systems difference from "traditional" radio systems in that a traditionalradio system uses a dedicated channel for each individual group of users, while digital "trunked" radio systems use a pool of channels which are available for a great many different groups of users.

Tradiontal two way radio system
For example, if police communications are configured in such a way that 12 traditional channels are required to permit citywide dispatch based upon geographical patrol areas, during periods of slow dispatch activity, much of that channel capacity is idle. While in a trunked radio system, the police units in a given geographical area are not assigned a dedicated channel, but instead are members of a talk-group entitled to draw upon the common resources of a smaller pool of channels.
What is the advantages of digital trunked radio system?
First of all, the digital trunked radio system can make better use of channel resources. Similar to cellular digital technology, digital walkie-talkies can load more users on a designated channel and improve channel utilization. This is a solution to frequency congestion.
Second, digital trunked radio system improve call quality. Because digital communication technology has an error correction function in the system, compared with analog walkie-talkies, it can achieve better voice and audio quality in a wider range of signal environments, and it will receive less audio noise and sound more clear.

Finally, the digital trunked radio system improves the integration of voice and data, and changes the weakness of the control signal that decreases with the increase in communication distance. Compared with similar integrated analog voice and data systems, the digital trunked radio system can provide better data processing. And interface functions, so that more data applications can be integrated into the same two-way wireless communication base station structure, the integration of voice and data services is more complete and more convenient.
With the development of science and technology and the diversification of demand scenarios, there will be more and more work to achieve digital trunked radio system. Not only goverment,police, but also school, business, commercial meeting, transportation can use digital trunked radio system to increase work efficiency. Therefore, the digital trunked radio system will have a broader application.
