Abstract
A system for providing communication in a distributed land mobile radio (LMR) system architecture. In some embodiments, the system includes a first controller associated with an LMR site. The first controller may be configured to control communication, via a communication channel, of a plurality of LMRs. In some embodiments, the system further includes a first repeater of a plurality of repeaters associated with the LMR site. The first repeater may include at least an active mode. The first repeater may be in the active mode to initiate a simulcast controller operation using the communication channel of the plurality of repeaters.
Claims20
A system for providing communication in a distributed land mobile radio (LMR) system architecture, the system comprising:
- a first voter comparator configured to receive at least a first signal from a device;
- a second voter comparator configured to receive at least a second signal from the device;
- and
- a third voter comparator configured to receive at least a third signal from the device,
- wherein an active voter comparator of one of the first voter comparator, the second voter comparator, or the third voter comparator receives a plurality of signals comprising the first signal, the second signal, and the third signal, compares signal strengths of the plurality of signals, and transmits a signal of the plurality of signals that has greatest signal strength.
A system for providing communication in a distributed land mobile radio (LMR) system architecture that includes a plurality of devices configured to communicate with one another via the system, the system comprising:
- a first controller configured to control communication between the plurality of devices;
- and
- a second controller configured to, upon failure of the first controller that is configured to control communication between the plurality of devices, control communication between the plurality of devices,
- wherein providing communication in the LMR system architecture comprises controlling transmission of a plurality of signals between the plurality of devices.
A system for providing communication in a distributed land mobile radio (LMR) system architecture that includes a plurality of devices configured to communicate with one another via the system, the system comprising:
- a controller configured to control transmission of a plurality of signals between the plurality of devices;
- a repeater configured to receive at least one signal of the plurality of signals, assign a launch time to the at least one signal of the plurality of signals, and transmit the at least one signal of the plurality of signals;
- and
- a transmitter configured to transmit the at least one signal of the plurality of signals to the controller that is configured to control transmission of the plurality of signals between the plurality of devices at the launch time.
