Output (English): The invented information transmission device for a system with a radiating waveguide (2), along which a mobile unit travels, comprises means for injecting an unmodulated carrier wave into said radiating waveguide (2), means (3, 4) for localized sampling along said radiating waveguide (2) of some of the energy of said unmodulated carrier wave, whereby the device further comprises modulator means (7, 8) for modulating said unmodulated carrier wave using a local modulation signal representing information addressed to said mobile unit, and radiating means (5) for radiating a modulated carrier wave in the direction toward said mobile unit. Claimed is also a method for systems using radiating waveguides along which a mobile unit travels, which method includes injecting an unmodulated carrier wave into said radiating waveguide (2), localized sampling along said radiating waveguide (2) of some of the energy of said unmodulated carrier wave, modulating said unmodulated carrier wave using a local modulation signal representing information addressed to said mobile unit, and radiating a modulated carrier wave to said mobile unit.
