More Information
Summary:Devices and methods are provided that permit interoperability between Radio over Internet Protocol (RoIP) devices and land mobile radio (LMR) devices. In one device according to the invention, a networked radio includes a wireless network transceiver, an LMR signal connector, and an analog-to-digital converter/digital-to-analog converter (ADC/DAC). A computer processor that inputs data from or outputs data to the ADC/DAC includes a sound architecture and a server. The server includes a digital audio buffer, a voice-activity detector, and a daemon. The daemon is configured to (1) collect data on one or more variables affecting a best-choice determination for transmitting a communications signal intended for retransmission to one or more LMR devices, and (2) make the best-choice determination based on the data collected.
