The Airtime Resource Model Of The OFDM Channel In The Task Of The IEEE 802.11 Network Efficiency Estimation

This article discusses the efficiency of the IEEE 802.11ac standard amendment from airtime resource usage point of view. An OFDM channel model is proposed as a function between its basic parameters and the application conditions. Analytical models are obtained for the data bits per OFDM symbol and the data frame transmission time as a function of the signal to noise ratio for the IEEE 802.11ac standard amendment. The model analysis shows that the error of the model is less than 6% for the most of the data frame size values. The proposed analytical models can be used to assess the effectiveness of the network and thus help in the design process of the networks.
