Récepteur de type “wake-up” radio à identification par empreinte fréquentielle


The Internet of Things (IoT) is described as the industrial revolution of the early 21th century. Innumerable communicating objects will be deployed in the coming years and one of the consequences will be the exponential growth of the IoT energy footprint. The use of ultra-low energy radio receivers (wake-up radios) is one of the envisaged solutions to reduce the energy consumption. By using such kind of receivers, the radio transceiver which consumes the most greedy part of energy of communicating objects, will be power supplied only during the active periods. In the scientific literature, the use of on-off keying (OOK) modulation together with envelope detector based radio part and a microcontroller unit is highlighted for the wake-up radios. The authors of this paper proposed an original approach consisting in a quasi-passive wake-up radio where the identification is done by the means of passive filters and the use of orthogonal frequency division multiplexing (OFDM) signal. This approach is validated through measurements on a functional prototype and, in this paper, the receiver sensitivity and the communication range are given.
