Patent ID: 10333599

Abstract:
Embodiments of the disclosure relate to antenna array beamforming in a remote unit(s) in a wireless distribution system (WDS). In this regard, a remote unit in a WDS includes an antenna array having a plurality of radio frequency (RF) antennas. The RF antennas transmit a plurality of modified downlink RF signals in a plurality of phases. A control circuit in the remote unit determines the phases to cause the RF antennas to transmit a formed radiation beam(s) in a radiation direction(s). The control circuit controls a plurality of phase shifters to generate the modified downlink RF signals in the phases. By supporting antenna array beamforming in the remote unit, it is possible to steer the formed radiation beam(s) according to a specific floor layout(s) to provide enhanced indoor RF coverage in the WDS. As a result, it may be possible to reduce deployment and/or installation costs of the WDS.
