Abstract
A system for communicating with wireless devices. The systems includes radio groups whose MIMO physical sectors overlap. The MIMO physical sectors communicate using different channels. The MIMO physical sectors overlap to form an area of overlap. Each radio group includes directional antennas and radios. Radios are selectively coupled to the antennas. The antennas that are oriented so that the physical sectors of the antennas overlap to operate as MIMO antennas and form the MIMO physical sector for the radio group. The antennas operate as a MIMO antenna.
