A receiver voting system is required to improve the talk-back capability of mobiles in the field.
Codan radio equipment is ideally suited for operation in receiver voting systems. These types of systems may require multiple receivers in a single subrack and combinations of receivers and transmitters. Each receiver output includes a COR line and several audio access points. These are typically used by the voter for receiver selection and transmitter steering. The generic system shown below allows remote mobiles to contact other remote users. The local RX 1 frequencies are back hauled to the base station. Site A uses a radio link. Site C uses a leased line. Site B is the resident Local base receiver. The voter will determine the “best” RX and rebroadcast the signal from the base on TX F2.
