As you may know, being able to effectively communicate with your workforce is of major importance in any industry. Without the ability to communicate with your team, you'll limit the amount of work you get done. Many businesses and public service organizations have adopted the use of radios for instant communications.
There are two main styles of radios designed for this purpose; conventional two-way radios and trunking radios. Both of these are very similar in terms of how they work, but only one can help improve the security and efficiency of communications during use.
Unlike conventional radios, trunking radios do not have user channel selection. The reason for this is because, with standard two-way units, anyone can switch over to a channel and participate in your conversation whether you want them to or not. With trunked radio systems, your communication is less likely to experience cross-talk, adding a layer of security to a mission-critical part of your workforce.
A trunked radio system is a complex type of two-way radio that allows the sharing of a few radio frequency bands between many users. Instead of assigning a radio channel to one particular organization at a time, users are instead assigned to a "talk group". When any person in that group wishes to talk with another member in their talk group, a vacant radio channel is found automatically by the system and the conversation takes place on that channel.
This form of communication is a packet-switching computer network. Radios send data packets (voice messages) to a computer-controlled channel to request communications with a specific talk-group. The controller then sends a signal to all radios linked to that talk group instructing them to automatically switch to the frequency indicated by the transmission. After the user is done speaking, all radios immediately return to the Control Channel to await further transmissions.
Through the use of trunking, radios can utilize the same sets of frequencies with less cross-talk, interruption, and errors since all messages must pass through a central computer for sorting and delivery. This method also allows for a greater volume of communications to pass through the same frequency bands because as soon as a line clears, the system automatically begins to transmit the next message regardless of which talk group is active.
Since its release in 1997, and with advancements made to this technology, users are now able to do far more in terms of securing their communications from misuse. Unlike conventional radio systems, a variety of trunking systems allow for voice encryption and the ability to lock out radios from talk groups and even entire networks.
In short, trunked radio systems allow multiple groups of users to share a small set of radio frequencies without accidentally hearing or talking over each other's conversations. Trunked radio systems primarily conserve limited radio frequencies and also provide other advanced security features to the users.Other Helpful Links
