INVESTIGATION OF WIRELESS CHANNELS ACCORDING TO THE STANDARD 802.11 IN THE FREQUENCY RANGE OF 5 GHZ FOR TWO SUBSCRIBERS

Abstract

In the given work the research of wireless channels of the family of standards of 802.11x in the frequency range of 5 GHz was taken into account taking into account the influence of architectural obstacles in the premises. As the main parameters for the research the effective transmission rate, the signal strength at the receiver input and the channel throughput are chosen. It has been established that the rate of transmission of information has a direct dependence on the signal transmission characteristic, therefore, to assess the level of signal fluctuations, it is necessary to use a confidence interval of power. On the basis of experimental research, a mathematical expression was obtained for evaluating the efficiency of wireless channels of the 802.11x family of standards for a frequency range of 5 GHz, taking into account the architectural obstacles in the room. It is established that in the presence of two subscribers in the network there are quite significant restrictions for high-performance modes.
