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.

Slave and master devices and methods using a preamble extension to set a power mode

A hub device is disclosed comprising a first antenna communicating with a peripheral device, a second antenna communicating with a remote station. In a first operation mode, transmission by the first antenna is at a first bit rate. Operation may be triggered to switch to a second mode in which a stream of data is received from the remote station, and there is a transmission to the first peripheral device, of data derived from the data stream, the transmission being from the first antenna while the stream of data is being received on the second antenna. In the second mode, the transmission from the first antenna is at a second bit rate that is faster than the first bit rate such that transmitting the derived data at the second bit rate uses a shorter duty cycle than required to transmit the derived data at the first bit rate.
