ABSTRACT:
In an information transmission device and method for systems using radiating waveguides along which a mobile travels, an unmodulated carrier wave is injected into the radiating waveguide. Some of the energy of the unmodulated carrier wave is sampled locally along the radiating waveguide. A local modulation signal representing information addressed to the mobile modulates the unmodulated carrier wave. The modulated carrier wave is radiated to the mobile.
