BI-BAND TERMINAL WITH COMPETING ACCESS OPERATED IN TWO ADJACENT TAPES

摘要

The present invention relates to a terminal for high speed transmission of video, audio or data signals in a home environment. It applies more particularly in the context of terminals operating according to the IEEE 802.1 1n standard and employing simultaneously several frequency channels in a predetermined frequency band, for example the WiFi band of 5 GHz. The terminal comprises M antennas (40), a MIMO device (20) capable of generating MIMO signals in said predetermined frequency band from baseband signals or vice versa, said MIMO device being able to process N MIMO signals simultaneously, and a switching device (30) for connecting the MIMO device to the M antennas. According to the invention, the MIMO device comprises two MIMO circuits (20a, 20b), one operating in a first subband of the predetermined band and the other in a second subband of the predetermined band, the two sub -bands being non-overlapping and the switching device (30) is adapted to connect said two MIMO circuits (20a, 20b) to the antennas (40) so that each of said M antennas is able to receive or transmit one of the MIMO signals of the first MIMO circuit and to receive or transmit one of the MIMO signals of the second MIMO circuit simultaneously. The switching device further comprises a filtering device (34) associated with each antenna for isolating, on reception, the MIMO signal of the first sub-band of the MIMO signal of the second sub-band received or transmitted by said antenna .
