A centrally managed network that automatically and dynamically selects a base station(s) from a pool on a site(s) and assigns it for use of an individual talk group for the duration of a call, after which it is returned to the pool for assignment to the next talk group caller. Trunked sites are connected via data links that allows users from the same talkgroup at different geographic locations to share a call.
Trunked radio shares base stations similar to the way a PABX shares telephone lines.
The automatic and dynamic sharing of a small number of radio frequencies among many users. A trunking system distributes message traffic among the available channels for greater efficiency and to reduce channel waiting time. In a trunking system, all aspects of radio operation are centrally managed, including RF channel selection and access.
