A system and method are provided for periodic stream admission control in an IEEE 802.11 network. The method comprises: at an access point (AP), receiving a transmit specification, including a requested bandwidth, from a quality of service station (QSTA); computing T<SUB>temp</SUB>, the time equivalent to the requested bandwidth; computing T<SUB>all</SUB>, the time already allocated; and, computing T<SUB>res</SUB>, the total time available. I<SUB>f</SUB>T<SUB>temp</SUB>+T<SUB>all</SUB><T<SUB>res</SUB>, then the QSTA is admitted. If T<SUB>temp</SUB>+T<SUB>all</SUB>>T<SUB>res</SUB>, the QSTA is not admitted. Some aspects of the method further comprise: monitoring the bandwidth of the admitted QSTA. In another aspect, the method: determines the bandwidth required by the admitted QSTA; and, modifies the bandwidth of the admitted QSTA in response to the determined QSTA requirements. In one aspect, the method: monitors channel conditions; and, modifies the bandwidth of the admitted QSTA in response to the channel conditions.
