Abstract

The throughput performance of IEEE 802.11 wireless LANs has been evaluated in relation to overhead. Sources of overhead are gap time, preamble, header fields for the PHY (physical) and the MAC (medium access control) layer, ACK (acknowledgement) frames, the TCP (transmission control protocol). The impact of this overhead can be modeled. After measuring the net throughput with 2.4 GHz products and detailed monitoring of actual exchange of frames, this modeling has been refined. The close fit between the results of measuring and of modeling for currently available 2.4 GHz product allows an accurate prediction for enhanced 2.4 GHz versions and new 5 GHz products
