Patent ID: 8737511

Claim:
A system comprising: m antenna arrays configured to receive a propagating radio frequency signal and configured to transmit a propagating radio frequency signal, each of the antenna arrays comprising: a plurality of antenna elements; and a beamformer configured to produce n different bi-directional beams using the plurality of antenna elements; and n multiple-input multiple-output transceivers (MIMO), each MIMO transceiver comprising: a MIMO receiver configured to process m different received signals, wherein an i-th received signal to a j-th MIMO receiver corresponds to a j-th beam of an i-th antenna array; and a MIMO transmitter configured to process m different transmit signals, wherein a v-th transmit signal from a z-th MIMO transmitter corresponds to a z-th beam of a v-th antenna array, wherein m, n, v, and z are integer number values, wherein i=1, . . . , m, j=1, . . . , n, and v=1, . . . m, wherein n≧2 and m≧2, wherein z=1, . . . , w, and wherein n≧w≧2.
