1. A communication system, comprising:
a plurality of distributed antenna circuits, including at least a first antenna circuit and a second antenna circuit; and
an access point (AP) coupled to the plurality of distributed antenna circuits, the AP including:
a plurality of transmit chains;
a plurality of receive chains; and
an antenna control circuit communicatively coupled to the plurality of transmit chains and the plurality of receive chains,
wherein:
the first antenna circuit is co-located with the AP and the second antenna circuit is remote from the AP; and
the antenna control circuit is configured to determine a subset of the plurality of distributed antenna circuits to communicatively couple to at least some of the plurality of transmit chains to transmit data to a wireless station (STA) that is in range of the subset of the plurality of distributed antenna circuits.
