1. A system for wirelessly communicating with provided wireless devices via a plurality of multiple-input-multiple-output (“
- MIMO”
) antennas, the system comprising;
a first radio group comprising a first MIMO physical sector for communicating using a first channel; and
a second radio group comprising a second MIMO physical sector for communicating using a second channel;
wherein;
the first MIMO physical sector overlaps at least 30 percent of an area of the second MIMO physical sector thereby forming an area of overlap;
a frequency of the first channel is different from a frequency of the second channel;
each radio group respectively further comprises;
a phased array; and
at least two radios coupled to the phased array, the at least two radios transmit and receive using the channel of the radio group, the radios cooperate with the phase array to form a plurality of physical sectors that use the channel of the radio group, each physical sector having an angle of coverage less than 360 degrees, each physical sector of the plurality at least partially overlaps the other physical sectors of the plurality to form the MIMO physical sector of the radio group, the physical sectors of the phased array operate as a MIMO antenna.

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.
