Дослідження безпровідного каналу стандарту 802.11n частотного діапазону 5 ГГц

Abstract

In this paper, was investigation of the effective speed of transferring information for the wireless channel of 802.11n standard in a non-licensed range of 5 GHz was conducted it this work, taking into account architectural obstacles and features of the half-duplex regime of work. For this purpose experimental studies and the analysis of dependencies of the effective speed of transferring information on the signal power at the entry of the receiver for a typical building with architectural obstacles were conducted. Based on the proposed network structure and conducted experimental investigations it was concluded that the effective speed of transferring information has a linear decline characteristic and architectural obstacles have the strongest influence on the high-performance regime of work for the channel of 40 MHz width. High stability of the effective speed of transferring information during the significant changes of the signal power at the entry of the receiver is typical for channels of 5 GHz range as well.
