The transmit window size of a Simple Packet Relay Transport protocol packet transmission system can determine the efficiency of transmission and the memory requirements of the transmitter. A sufficiently large transmit window must be maintained to avoid transmission waits which can reduce the utilization of available transmission path bandwidth. However, an oversize window will require excess buffer capacity and therefore utilize additional storage space on the transmitter. A balance in window size is dynamically achieved through monitoring of the buffer write operations to determine the accessibility of the transmit buffer based upon packet transmission utilization and packet consumption acknowledgment.

A Hybrid Coordination Function (HCF) implementation wherein an access point's existing (E)DCF transmit queues are augmented by at least one strict priority HCF transmit queue. The HCF queues are only used to schedule downlink data and CF-Poll transmissions are used for admitted downlink flows and for uplink flows. The 802.1D user priority value is used to select the HCF queue for an admitted flow. The strict priority HCF transmit queues are always serviced first, in priority order before any other (E)DCF transmit queue. The channel is considered busy to (E)DCF transmit queues while the strict priority queues are being serviced. An admissions control mechanism is used to control data flows and prevents the strict priority traffic from starving (E)DCF traffic. A single, simple AP scheduler is used for scheduling both polling times and station wakeup times.

Frequencies at which significant degradation in the communication occurs are also avoided. In addition, for frequency hopping devices, hop sequence is readjusted in accordance with the newly assigned channels.
