WI-FI RADIO DISTRIBUTION NETWORK STATIONS AND METHOD OF OPERATING WI-FI RDN STATIONS

摘要

A Wi-Fi radio distribution network (RDN) station is provided for use in a wireless communications network comprising a plurality of wireless stations. The Wi-Fi RDN station comprises a multiple-input-multiple-output (MIMO) receiving system configured to operate in accordance with a channel estimation MIMO receiving scheme; and a RDN connected to the MIMO receiving system. The RDN comprises at least one beamformer arranged to be fed by two or more antennas, wherein each of the beamformers includes a combiner configured to combine signals coming from a plurality of antennas associated with the respective beamformer into a single signal. The MIMO receiving system is configured to perform one or both of channel estimation using a single antenna or beamforming. Both channel estimation and beamforming may be based on one or more packets addressed to one or more wireless stations in the communications network other than the Wi-Fi RDN station.
