摘要： Embodiments of the disclosure relate to systems and methods for isolating a base station beacon and gas reading transmission channel(s) based on a single radio wireless gas detection system. A gas detector may communicate on a first channel (e.g. a beacon channel) constantly listening to the base station beacon information. At a pre-defined interval (e.g. every 60 seconds), the gas detector radio may switch to a second channel (e.g. a data channel) to transmit gas reading data as well as the base station information to a central server. Software on the server may complete a triangulation algorithm to determine the location of the gas detector, using information obtained by the detector from the beacons.
