Abstract:
1. A first intelligent backhaul radio comprising: a plurality of directional receive antenna arrays for simultaneously receiving a plurality of receive RF signals at the first intelligent backhaul radio, the plurality of receive RF signals comprising one or more of a plurality of transmit symbol streams transmitted by at least a second intelligent backhaul radio, wherein at least one of said one or more of said plurality of transmit symbol streams is for communication between the second intelligent backhaul radio and the first intelligent backhaul radio, wherein each of said plurality of directional receive antenna arrays comprise a plurality of receive antenna sub-arrays, wherein each of said plurality of receive antenna sub-arrays comprise a plurality of receive antenna elements; one or more demodulator cores, wherein each demodulator core demodulates one or more receive symbol streams to produce one or more respective receive data interface streams; a plurality of receive RF chains to convert the plurality of receive RF signals to a plurality of respective receive chain output signals; a frequency selective receive path channel multiplexer, interposed between the one or more demodulator cores and the plurality of receive RF chains, the frequency selective receive path channel multiplexer to generate said one or more receive symbol streams from the plurality of receive chain output signals; one or more selectable RF connections that selectively couple certain of the plurality of said receive antenna sub-arrays to certain of the plurality of receive RF chains, wherein the number of receive antenna sub-arrays that can be selectively coupled to receive RF chains exceeds the number of receive RF chains that can accept receive RF signals from the one or more selectable RF connections; and a first radio resource controller,
