Abstract
A Multiple-Input Multiple-Output (MIMO) device comprises an array of multiple antennas and a circuitry configured to receive, using the array of multiple antennas, a plurality of calibration signals from a plurality of proximate wireless MIMO devices, calibrate the wireless MIMO device based on the received calibration signals and based on known directions from the wireless MIMO device to each of the proximate wireless MIMO devices, and drive the array of multiple antennas to emit a beam-formed calibration signal to each of the proximate wireless devices in order to enable each of the proximate wireless MIMO devices to calibrate itself.
