Throughput analysis of wireless channel in boosting modes

Abstract

In addition to the basic transmission mode, leading manufacturers of integrated circuits for wireless devices such as Atheros, Broadcom and TexasInstruments insert a number of additional modes into their products, aimed at increasing the throughput of wireless channel of the IEEE 802.11g standard, the so-called boosting modes. The analysis of the additional boosting modes for the wireless channel of the IEEE 802.11g standard was performed in the paper. It is shown that in contrast to the basic transmission mode for these modes, there are no mathematical models and throughput studies of wireless channels which operate in these modes. The mathematical models for calculating the maximum throughput of the wireless channel of the IEEE 802.11g standard for boosting modes: CompressionMode, BurstingMode, FastFrames and DynamicTurbo were obtained. Mathematical models analytically express the dependence of the maximum throughput of the wireless channel on the data frame size. Using the obtained models, a study of the maximum throughput of the wireless channel of the IEEE 802.11g standard for the given transmission modes was carried out. Studies have shown that these modes provide an increase in the maximum throughput of the wireless channel from 33% to 50% compared with the basic transmission cycle of the IEEE 802.11g standard. Based on the studies, a conclusion on the feasibility of using these modes for increasing the throughput of wireless networks was made. For each of the modes, upper limits of the throughput increase of the wireless channel of the IEEE 802.11g standard were defined.
