Abstract
The results of characteristics research of the wireless network of IEEE 802.11n, which operates in a mixed mode using a single spatial channel in a 20 MHz frequency band, are described in this paper. The requirements for the parameters of audiovisual information transmission in IP networks are analyzed. The paper presents the results of calculations of the network throughput, the probability of occurrence of collisions and the probability of successful transfer of the data frame in the saturated network, obtained a mean delay time and uneven transmission of packets. The calculation equations are based on the concept of a virtual contention window. Based on the results of the calculations, estimates were made regarding the efficiency of the application of the network in accordance with the IEEE 802.11n for the transmission of audio-visual information.
