Abstract (en)
[origin: WO2022117950A1] The invention relates to a method for controlling the backscattering of an ambient signal emitted by an emitter device (SO). The method includes steps implemented by a transmitter device (D_TX) configured to backscatter the ambient signal: - acquiring (E20_1) a measurement (M_CUR) of power received from the emitter device; - evaluating (E20_3) a criterion (CRIT) consisting of at least checking whether a distance (D_COUV), counted from a position occupied by the transmitter device during the acquiring of the current measurement and in which a given reception quality value (VAL_C) is attained for a signal obtained by backscattering the ambient signal, is in a given interval (I_COUV), the distance of coverage being defined as a function of the measurement and the value; - if the criterion is met, ambient backscattering (E20_4) of the ambient signal; - if the criterion is not met, absence of ambient backscattering (E20_5) of the ambient signal.
