Abstract
A multiple-input, multiple-output (MIMO) transceiver comprises a plurality of RF chains, a plurality of antennas, a plurality of switching components, and control circuitry operatively coupled to the plurality of switching components. In some examples, a total quantity of RF chains included in the plurality of RF chains is equal to a first value, and a total quantity of antennas included in the plurality of antennas is equal to a second value that is less than the first value.
