A major advantage of trunked radio systems is that they can be used to provide a shared commu- nications system for more than one group of radio users. This allows system costs to be spread over the different user groups. Frequently, the groups shar- ing the system will have no reason to interact with each other as their functions are very different. In fact, it may be desirable to limit or prevent the inter- action between certain groups either for reasons of security or due to equipment incompatibilities.
