The article presents data transmission methods in IEEE 802.11 wireless LAN standard, including transmission efficiency improving methods like block acknowledge and two variants of frame aggregation. On the basis of their operation, an analytical model is derived which allows for estimation of protocol efficiency and effective throughput under perfect conditions for various protocol parameters. With this model, all transmission methods are analysed for their efficiency for two currently used physical layers, namely, OFDM (802.11a/g) and HT (802.11n). The calculation results are presented on graphs and discussed. Finally, so-called throughput upper limit is calculated for all the methods considered in the paper.
