CA 2464612
A leaking waveguide (12) is provided so that it meanders on the ceiling of a room (11) where a radio LAN works. One end of the leaking waveguide is connected to a radio base station device (13), while the other end is connected to a terminating device (14). The radio base station device (13) communicates, by radio, with a radio terminal device (17) via the leaking waveguide (12) by means of the modulation/demodulation of orthogonal frequency division multiplex modulation (OFDM) scheme.
L'invention concerne un guide d'onde (12) à onde de fuite serpentant sur le plafond d'une pièce (11) dans laquelle un réseau radio LAN fonctionne. L'une des extrémités du guide d'onde à onde de fuite est connectée à un dispositif radio (13) de station de base. Ce dispositif (13) communique par radio avec un dispositif radio (17) de terminal via le guide d'onde (12) à onde de fuite à l'aide de la modulation/démodulation d'un mécanisme de multiplexage par répartition orthogonale de la fréquence (OFDM).
