Abstract
Frames of a first and second type with a common preamble that are periodically transmitted by a master device () are received at a slave device () that is maintained in a low powered mode, and periodically set in a higher-powered mode to receive and process the received frames based on a slave clock () in a period prior to an expected transmission of the common preamble of each frame from the master device () to detect a preamble extension of a frame of the second type in the period. The slave device () returns to a low powered mode when no preamble extension is detected in the period. Information is received from and/or transmitted to the master device () by the slave device () when a preamble extension is detected. The slave device () is returned to the low powered mode after the information has been received and/or transmitted.
