Abstract
A method is described for determining at least one location for backscattering, by at least one transmitter device and to at least one receiver device, of an ambient radio signal, the transmitter device being associated with a zone, a backscattering and a non-backscattering operating state, and a working frequency band. Further, the method is implemented by the transmitter device when it is in the non-backscattering state and comprises travel of the transmitter device in at least one part of the zone, during which the transmitter device acquires, in the working band and in at least one location of the part of the zone, a measurement of electromagnetic power received by the transmitter device, and compares the measurement with a determined threshold, the location associated with the measurement being determined as a location for backscattering if the measurement is greater than the threshold.
