In this work, radio transmitters Wi-Fi networks (access points Wi-Fi) and their influence on each other in terms of loaded Wi-Fi network are studied. The purpose of the work is providing the best quality of wireless data transmission by improving the efficiency of the access points in a changing radio environment, active and passive jamming using information about the level of the signal receivers and, if connected to transmitters of different client devices. Based on these experiments, the appropriate adjustment of the parameters of the transmitters. In the process studied the following concepts: methods of medium access in wireless networks, modulation techniques for digital signals, the architecture of WLANs, the IEEE 802.11 standard and the Wi-Fi settings of the router, which regulate the quality of transmitting and receiving data between client devices and access points Wi-Fi.

Implemented experiments to determine delays of reception-transmission and data packet loss when communicating with the host, and the experiments on the measurement of speed of reception and transmission between hosts at various conditions of the radio environment (active and passive interference) for different number of client devices connected to Wi-Fi router. Based on the results obtained from the experiments, performed the analysis and developed the algorithm to adjust the parameters of Wi-Fi transmitters in real time. The results can be useful when creating automated system of adjustment of parameters of radio transmitters Wi-Fi networks in a changing radio environment.
