1. A communications device comprising:
a plurality of antennas comprising:
a set of first-band antennas configured to communicate in a first frequency band;
a set of second-band antennas configured to communicate in a second frequency band; and
a set of dual-band antennas configured to communicate in the first frequency band and the second frequency band;
a plurality of receive chains comprising:
a plurality of first-band receive chains configured to receive signals in the first frequency band; and
a plurality of second-band receive chains configured to receive signals in the second frequency band;
a plurality of transmit chains comprising:
a plurality of first-band transmit chains configured to transmit signals in the first frequency band; and
a plurality of second-band transmit chains configured to transmit signals in the second frequency band; and
a plurality of switches configured to connect respective antennas of the plurality of antennas to respective receive chains of the plurality of receive chains and respective transmit chains of the plurality of transmit chains,
wherein the plurality of switches comprises:
a first switch configured to connect one of the set of first-band antennas and one of the plurality of first-band receive chains;
a second switch configured to connect one of the set of second-band antennas and one of the plurality of second-band receive chains;
a third switch configured to connect one of the set of first-band antennas and one of the plurality of first-band receive chains; and
a fourth switch configured to connect one of the set of second-band antennas and one of the plurality of second-band receive chains.
