Configuring radiofrequency sensing nodes

Abstract

A method of configuring a radiofrequency-based sensing system comprising a first and a second node; wherein the first and the second nodes are operable in an active mode and in a sleep mode according to a wireless communication protocol; wherein the first node comprises a transmitter arranged for transmitting a radiofrequency beacon signal for presence and/or location detection and the second node comprises a receiver arranged for receiving the transmitted radiofrequency beacon signal; wherein the method comprises: switching an operation mode of the first and the second nodes from the sleep mode to the active mode at a predetermined time instance; receiving, at the first and/or the second node, a wireless communication signal indicative of a wakeup time duration for the first and the second node; wherein the wireless communication signal is implemented according to the wireless communication protocol; activating the first node transmitter, upon receiving the wireless communication signal, to transmit the radiofrequency beacon signal during the wakeup time duration; activating the second node receiver, upon receiving the wireless communication signal, to receive the transmitted radiofrequency beacon signal during the wakeup time duration; processing the received radiofrequency beacon signal for presence and/or location detection; switching the operation mode of the first and the second node to sleep mode upon expiration of the wakeup time duration.
