wireless station when the ap 310 transmits each wireless station 312 320 receives the signal decodes it and determines if the signal is meant for that wireless station this may be accomplished by transmitting a unique query to the stations to inquire about any data traffic the station has to transmit to the ap according to one aspect of the disclosure the ap may query two or more stations simultaneously or in rapid succession once a signal is received by that station and it is determined that the signal is meant for that particular station the station transmits a reply to the ap the reply may indicate the amount of data to transmit or that there is no data traffic to transmit alternatively if there is no data to transmit the station may forgo transmission the ap 310 when it receives a reply from a station will signal to that station that it may begin to transmit data the ap may signal a predetermined amount of time or data within which the wireless station must limit its transmission the wireless station will buffer any data it cannot transmit within the predetermined amount of time and transmit it at the next available opportunity this allows for the ap to function as a network controller and dynamically control the data flow throughout the network when used with the other techniques herein described the ap may provide priority to certain wireless stations by maintaining a queue of priority stations thus increasing the quality of service for that station.
