Abstract
A device is configured to perform a method for performing a radio frequency (RF) calibration of a Wi-Fi device. The method includes transmitting, by a transmitter, a CTS (clear-to-send)-to-self frame, the CTS-to-self frame having a duration field indicating a first time duration of the RF calibration. The method also includes waiting, by at least one processor, for a second time duration associated with a distributed inter-frame space (DIFS) time period. The method further includes performing, by the at least one processor, the RF calibration.
