The new regional system is a digital trunked system. And it IP based.These distinctionsare important in several ways. By digitizing the human voice at the source, clarity can be preserved throughout the transmission process. When the digital signals are converted back to an audible sound at the receiving end, the sound reproduction is superior, clearer, and more easily understood by the listener. Trunking Trunking is perhaps the least understood feature of this modern system. But it is the trunking feature that creates the capacity for multiple simultaneous conversations on a limited number of radio frequencies. Conventional two-way radio transmissions generally occur on a single channel.This scheme could be likened to the old telephone party line. Only one outgoing line (channel) is available for a number of users. If you want to call someone, you may have to wait your turn. When the line is busy, you may have to wait a long time to get in a word. Not a pleasant situation to deal with when an emergency arises. With digital trunking, a computer selects any one of a number of pooled channelsthat may be available at any given moment. This happens in an instant. When you press the talk button on your radio, a signal is sent through the system to a central computerized switch on a"control channel."The computer scans the list of channels, selects an available free channel, and, in the same instant, switches the receivers of each of the other radios on your selected talkgroup. to the available channel. Thus, any given conversation on the system may take place on several frequency channels. But to the users, the dialogue is seamless. The use of this trunking technique exponentially increases the capacity of the system to handle conversations, making much more efficient use of the available spectrum.
