Title: TECHNIQUE FOR READING ENERGY-SAVING METERS AT THE SMART METER LEVEL
Abstract:
The invention relates to a method for establishing a communication between a gateway and a communication module, comprising: • periodically broadcasting a synchronisation signal from a gateway, the duty cycle DC=Dx/Tx between the duration of the transmission window (28) Dx of the synchronisation signal and the duration of the broadcasting period Tx being less than 50%, • periodically activating a receiver of a communication module activated during a waking window (29), the duration of the waking 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 of the synchronisation radio signal by the receiving communication module during a recovery (30) between a so-called waking window (29) and a so-called transmitting window (28), • broadcasting a data message (20) from a transmitter of the communication module, • and receiving the data message by a receiver of the gateway.
