The article considers the initial stage of ensuring electromagnetic compatibility in mobile communication objects - the study of the levels of norms of industrial interference in terms of identifying and eliminating the detected inconsistencies. The scheme of sequence of identification and exclusion of sources of radio interference is given. The methods of elimination of exceeding the norms of the levels of industrial radio interference for the transition to the subsequent stages of testing are considered. Recommendations are given in the part of design and technological and schematic features of the process of designing a mobile communication object to minimize the risks of passing tests on electromagnetic compatibility. Methods for eliminating the redundancy of the frequency separations of adjacent radio-electronic means are described. An optimization of a two-stage method for measuring the isolation between antennas is proposed. The implementation of the above recommendations in the design process and the proposed sequence of identifying and eliminating inconsistencies will allow for a minimum time to pass the stage of studying the levels of industrial interference standards with a positive result.
