Abstract
A base station is configured to transmit a substantially unidirectional RF beam to a donor. The donor is in close proximity to a building, and provides communication signals corresponding to the unidirectional RF beam to a relay inside the building. The relay includes a phased array antenna panel having a staggered antenna assignment with predetermined phases for antennas in the phased array antenna panel to produce omnidirectional broad-beam RF signals inside the building.
Claims15
A wireless communications system comprising:
- a base station configured to transmit a substantially unidirectional RF beam to a donor;
- said donor being in close proximity to a building, and providing communication signals corresponding to said unidirectional RF beam to a relay inside said building;
- said relay including a phased array antenna panel having a staggered antenna assignment with predetermined phases for antennas in said phased array antenna panel to produce omnidirectional broad-beam RF signals inside said building.
An outphasing relay transmitter utilizing a phased array antenna panel, said outphasing relay transmitter comprising:
- a combiner configured to combine a plurality of beamforming signals into a composite input signal;
- a decomposition block configured to decompose the composite input signal into a first decomposed RF signal and a second decomposed RF signal;
- said first decomposed RF signal coupled to a first power amplifier;
- said second decomposed RF signal coupled to a second power amplifier;
- a first plurality of staggered antennas being dedicatedly assigned to said first power amplifier;
- a second plurality of staggered antennas being dedicatedly assigned to said second power amplifier;
- said first and second plurality of staggered antennas being associated with predetermined phases so as to produce omnidirectional broad-beam RF signals.
