Systems of adaptive transmit antennas to the propagation conditions for broadcast radioelectric

To broadcast synchronized radio waves in at least one frequency band in a predetermined area, antennas (AS, ATI, AE) emit waves to respective coverage areas in which receivers (RQ, RB) measure of wave characteristics issued and transmit them to a central server (SC). The server analyzes the characteristics based prediction models for broadcasting waves in the area to determine the adjustment parameters for the antennas. The server transmits the setting parameters to the antennas to steer in order to offer a wider variety of radio broadcast and optimize coverage areas according to various wave propagation modes.
