Abstract: A transmission frame is communicated to cause a media idle measurement period on a contention based communication media. The media idle measurement period (i.e., “quiet period”) provides a period of inactivity on the communications medium that may be used to detect for the presence of foreign signals such as radio broadcast interference, noise, or other signals, or may be used for calibration of circuitry coupled to the communications medium. Idle measurement periods may be caused regularly (e.g., periodically). The transmission frame may include an explicit instruction for the media idle measurement period or may cause the media idle measurement period by simulating a collision on the communications media.
