Antenna array beamforming in a remote unit(s) in a wireless distribution system (wds)

A wireless distribution system (WDS), comprising:

• a central unit;
• and
• a plurality of remote units configured to:
• receive a plurality of downlink electrical communications signals from the central unit;
• and
• provide a plurality of uplink electrical communications signals to the central unit;
• wherein one or more of the plurality of remote units each comprises:
• an antenna array comprising a plurality of radio frequency (RF) antennas configured to transmit a plurality of modified downlink RF signals in at least one formed radiation beam in at least one radiation direction;
• a plurality of phase shifters configured to:
• phase-shift a plurality of downlink RF signals to generate the plurality of modified downlink RF signals in a plurality of phases, respectively;
• and
• provide the plurality of modified downlink RF signals to the plurality of RF antennas in the antenna array;
• and
• a control circuit configured to:
• determine the plurality of phases to cause the plurality of RF antennas to transmit the plurality of modified downlink RF signals in the at least one formed radiation beam in the at least one radiation direction;
• and
• control the plurality of phase shifters to generate the plurality of modified downlink RF signals in the plurality of phases, respectively.
