WLAN is an active research topic with considerable work carried out in the areas of performance analysis, QoS provisioning, admission control, voice/video streaming, network coding, security etc. In this work the performance of the IEEE 802.11b WLANs has been derived quantitatively by adopting novel technical procedures and utilizing the exact parameters as advertised by the IEEE 802.11 LAN/MAN Standards Committee. Two metrics namely the theoretical maximum throughput (TMT) and the maximum number of packets transmitted per second (PPS) have been used for this purpose. Numerical calculations demonstrate that the measured throughput is generally well below the expected throughput depending on the data packet sizes, acknowledgment packets, preambles, headers, and checksums etc. From theoretical calculations it is obtained that for short preamble, 11 Mbps data rate and payload size of 1472 bytes (i.e. for a maximum data transmission unit of 1500 bytes), the TMT is 6.24 Mbps and the PPS is 529.
