Abstract (en)
[origin: WO2019207261A1] The method (400) for wireless communication between at least one energy-autonomous risk detection terminal and a unit communicating with each terminal includes, iteratively: - a step (405) of transmission of a synchronization signal by the communicating unit, - a primary step (410) of waking the terminal, - a step (411) of reception of the synchronization signal by the terminal, - a step (415) of synchronization, by the terminal, of a clock and of an oscillation frequency of a temperature compensation-free quartz resonator of said terminal with the received signal, - a primary step (420) of placing the terminal in standby, - a secondary step (425) of waking the terminal, - a step (430) of wireless sending, by the terminal, of a message to the communicating unit, and - a secondary step (435) of placing the terminal in standby.
