摘要：
A method for establishing a communication between a gateway and a communication module, comprising: periodically radiobroadcasting from a gateway a synchronization signal, the duty cycle DC=Dx/Tx between the duration of the emission window Dx of the synchronization signal and the duration of the radiobroadcasting period Tx being less than 50%; periodically activating a receiver of a communication module activated during an awake window, the duration of the awake window being less than the duration Tr of the activation period, the duration Tr of the activation period being equal to Tr=Tx/(1+DC); receiving the synchronization radio signal by the receiver of the communication module during an overlap between a said awake window and a said emission window; radiobroadcasting a data message from an emitter of the communication module; and receiving the data message by a receiver of the gateway.
