Abstract
A process for generating at least one backscattering zone, by at least one transmitter device and to at least one receiver device, of an ambient radio signal emitted by at least one source; and a process for generating at least one reception zone, by the receiver device, of the backscattered ambient signal. The process for includes: determining an emission constraint, when it is respected by the source, for generating at least one backscattering zone in which the received electromagnetic power is greater than a determined threshold, called “backscattering threshold”, and/or generating at least one reception zone in which the received electromagnetic power is less than a determined threshold, called “reception threshold”; and transmitting, by the source, with respect to the emission constraint.
