1. A receiver for a wireless local area network (WLAN), the receiver comprising:
- a radio modem adapted to receive, from a transmitter of the WLAN, a transmission signal containing a time stamp value;
a first register adapted to receive the transmission signal from which the time stamp value is retrieved;
a timer adapted to initiate a count sequence based on the time stamp value and generate a timer control signal based on the count sequence; and
a controller adapted to control operations of the receiver based on the timer control signal from the timer.

Abstract
A wireless local area network apparatus includes a transmitter and a receiver in which operation of the receiver is accurately synchronized with periodic signals from the transmitter. The periodic signals contain timing data indicating the state of a timer in the transmitter at the time the signal containing that data was transmitted and this timing data is retrieved from the signal when received by the receiver and loaded in a timer for controlling operation of the receiver.
