The article deals with the optimization of the wireless hotspot installation of corporate LAN or distance learning networks built on the basis of the IEEE 802.11 standard. Recommendations for the optimal installation of hotspot is based on the analysis of the quality of speech information. The speech quality analysis is based on the estimation of power spectral density distortion. As a result of the analysis, the dependencies of the distortion of the spectral power density of the transmitted message on the distance between the transmitter and the receiver in different frequency ranges were obtained.
