Claims37
A wireless base station or access point comprising:
- a multiplicity of unitary radios, where each unitary radio includes a multiplicity of radio transceiver chains and each unitary radio is configured to transmit a data channel that is independent of data channels transmitted by other unitary radios;
- and
- a multiplicity of independently configurable antennas, where at least one of the configurable antennas has two ports and is a travelling wave antenna, a leaky wave antenna or a metamaterial leaky wave antenna, and where the at least one configurable antenna is excited in substantially orthogonal modes concurrently by coupling two or more radio transceiver chains of a unitary radio to one or both of the ports, and where the excitation of the configurable antenna radiates two or more different beams that transmit data from the data channel at substantially the same frequency.

- and
- an interface matrix coupled to the multiplicity of unitary radios and the multiplicity of antennas, the interface matrix configured to at least selectively interconnect a first radio transceiver chain to a first port of the at least one antenna to generate a first beam and interconnect a second radio transceiver chain to the first port or a second port of the at least one antenna to generate a second beam different from the first beam concurrently.
