US 2014/0273916 A1 · DISTRIBUTED SIMULCAST ARCHITECTURE

Abstract

A system and method for providing communication in a distributed LMR system architecture is provided herein, wherein the system includes a plurality of LMR subsystems interconnected by a data network. In some embodiments, a subsystem may include a distributed simulcast architecture comprising a plurality of LMR sites, each site having a subsystem controller and a plurality of repeaters. In one embodiment, one subsystem controller operates in an active mode and the remaining subsystem controllers operate in standby to provide redundancy. The repeaters include integrated voter comparator and simulcast controller functionality and circuitry. In some embodiments, the repeaters are operable in an active or standby mode, wherein repeaters in the active mode perform voter comparator and simulcast controller functionality. The distributed simulcast architecture provides simulcast controller and voter comparator redundancy, network failure redundancy, and site redundancy.

Dependent claims

A system for providing communication in a distributed land mobile radio (LMR) system architecture, the distributed LMR system architecture comprising one or more subsystems in communication with a data network, the system comprising:

one or more LMR sites comprising at least one of the one or more subsystems;
one or more subsystem controllers disposed at each of the one or more LMR sites comprising the at least one subsystem, each subsystem controller having at least an active mode and a standby mode, wherein at least one subsystem controller is operable in the active mode to control communication between the one or more LMR sites in the at least one subsystem;
and
one or more repeaters disposed at each of the plurality of LMR sites in the at least one subsystem, each of the repeaters operable to provide a communication channel,
wherein each repeater has at least an active mode and a standby mode, and wherein at least one repeater is operable in the active mode to perform at least one of a simulcast controller operation and a voter comparator operation.
