Disclosed are systems, methods, computer program products and computer data signals for broadcasting a beacon packet to one or more client stations and for processing a beacon packet. The beacon packet includes a preamble, a header and a data portion. In one broadcasting method, it is determined if there is any data buffered for any of the client stations. If there is data buffered, a traffic indicator flag located before the data portion of the beacon packet is set to a first logic value. If there is not any data buffered, the traffic indicator flag is set to a second logic value. The beacon packet is broadcast to the client stations.
