Abstract (en)
[origin: WO2007057591A1] In order to broadcast synchronized radio waves in at least one frequency band in a predetermined territory, antennas (AS, ATI, AE) transmit waves toward respective coverage areas in which receivers (RQ, RB) measure characteristics of the transmitted waves and transmit them to a central server (SC). The server that analyzes the characteristics according to forecasting models on the broadcasting of waves in the territory in order to determine adjustment parameters for the antennas. The server transmits the adjustment parameters to antennas for controlling them in order to provide a larger diversity of radio broadcasting services and to optimize the coverage areas according to different wave propagation modes.
