1. An apparatus comprising:
a plurality of wireless interfaces, each wireless interface comprising a multiple-input multiple-output (MIMO) wireless interface comprising:
a data port for receiving data for transmission over an air interface and outputting the data received over the air interface, and
a plurality of antenna ports;
an antenna switch fabric coupled to each of the plurality of antenna ports of each of the plurality of wireless interfaces, and further coupled to a plurality of antennas;
wherein each wireless interface is operative to:
for each antenna port of the plurality of antenna ports of a wireless interface that is used for receiving, control the antenna switch fabric to select, based on at least a first signal parameter associated with at least one antenna, a receive antenna, and
for each antenna port of the plurality of antenna ports of a wireless interface that is used for transmitting, control the antenna switch fabric to select, based on at least a second signal parameter associated with at least one antenna, a transmit antenna; and
wherein the antenna switch fabric is operative to, based on at least the control by each wireless interface, route radio frequency (RF) signals between the antenna ports and corresponding selected antennas of the plurality of antennas.
