Summary: The urgency of the topic is determined by the active development of wireless technology for the transmission of information and the need for research.
The purpose of this work is the study of the possibility of applying a compensatory modulation radiometric method to determine the bandwidth of the channel of the centimeter range.
To achieve this goal, the following tasks are solved: to conduct an analytical review of information sources on the topic of the dissertation; to explore the possibility of using the compensation-modulation method to determine the bandwidth of the сm-band channel; to develop a compensation-modulation method for determining the bandwidth of the radio channel cm-range; carry out an experimental verification of the developed method.
The object of research is the radio channel of the сm-band of wavelengths.
The subject is the bandwidth of the radio channel сm-band.
Methods of research are methods of mathematical analysis – for choosing a radio channel model, and mathematical statistics – for processing the measurement results; experimental research methods related to radiometric apparatus; swarm; Methods of computer modeling using Matlab2018 for modeling the transmission of information through the communication channel.
The scientific novelty of the obtained results is to apply the compensating modulation measurement method for studying the spectral characteristics of the signals of the channel of the сm-band.
The practical value of the results. The compensation-modulation method for determining the channel bandwidth cm-range is proposed, which is simpler than the known and can be used in the design and operation of communication networks.

Keywords: compensation-modulation method, cm-band communication channel, wi-fi.
