Title (EN) RADIO OVER INTERNET PROTOCOL DEVICES AND METHODS FOR INTEROPERABILITY WITH LAND MOBILE RADIO DEVICES
(FR) PROCÉDÉS ET DISPOSITIFS DE RADIO SUR IP POUR UNE INTEROPÉRABILITÉ AVEC DES DISPOSITIFS RADIO MOBILES TERRESTRES
Abstract:
(EN) 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.
(FR) L'invention concerne des dispositifs et des procédés qui permettent une interopérabilité entre des dispositifs de radio sur IP (RoIP) et des dispositifs de radio mobile terrestre (LMR). Dans un dispositif selon l'invention, une radio en réseau comprend un émetteur-récepteur de réseau sans fil, un connecteur de signal LMR, et un convertisseur analogique-numérique/convertisseur numérique-analogique (CAN/DAC). Un processeur informatique qui entre des données à partir du CAN/DAC ou qui délivre des données au CAN/DAC comprend une architecture sonore et un serveur. Le serveur comprend un tampon audio numérique, un détecteur d'activité vocale et un démon. Le démon est configuré afin de (1) collecter des données sur au moins une variable affectant une détermination de meilleur choix pour émettre un signal de communication destiné à une retransmission à un ou plusieurs dispositifs LMR, et (2) d'effectuer la détermination du meilleur choix sur la base des données collectées.
