Claim:
1. A radio comprising: one or more demodulator cores, wherein each demodulator core is configured to demodulate at least one receive symbol stream; a plurality of receive radio frequency (RF) chains, wherein each receive RF chain is configured to convert from a receive RF signal to a receive chain output signal; one or more modulator cores, wherein each modulator core is configured to produce at least one transmit symbol stream; a plurality of transmit radio frequency (RF) chains, wherein each transmit RF chain is configured to convert from a transmit chain input signal to a transmit RF signal; a first directional antenna array comprising a plurality of first directional antenna sub-arrays, wherein each first directional antenna sub-array comprises a plurality of first directional antenna elements, and wherein each first directional antenna sub-array is coupled or couplable to at least one of the plurality of receive RF chains; and a second directional antenna array comprising a plurality of second directional antenna sub-arrays, wherein each second directional antenna sub-array comprises a plurality of second directional antenna elements, and wherein each second directional antenna sub-array is coupled or couplable to at least one of the plurality of transmit RF chains; wherein at least one first directional antenna sub-array is spatially offset relative to at least one other first directional antenna sub-array in a first arrangement; and wherein said at least one first directional antenna sub-array is also spatially offset relative to at least one second directional antenna sub-array in a second arrangement.
