The Necessity to Assess the Electromagnetic Environment Near 5-G Radio-Emitting Objects with Instrumental Procedure

Abstract

The features of the new 5G standard if compared to the currently used 4G lie within a significant frequency range expansion, and the implementation of the Internet of things. They made it impossible to expand the existing safety standard of broadband cellular network construction in large cities to the new standard. Differences between the Western and Russian approaches to the maximum permissible power level assessment and the lack of publications on the subject prompt measurement experiments in order to obtain an approximate electromagnetic environment assess near radio-emitting objects. At the preliminary stage of the measurements, it is necessary to choose the right measuring instruments and procedures, since the choice determines the price-quality relationship of the experiment. In the paper the results of the analysis for the known measuring instruments are given with an account to the special requirements formulated according to 5G standard features. The conclusion on the availability of the measuring instruments with the required characteristics is made. It is shown that the experiment efficiency depends on the measurement area dimensions and the measurement points spacing. In case of reflector antenna of 0.9 m diameter operating at 6 GHz the number of measurement points can be reduced without a loss of accuracy if the measured antenna passport data as well as the recommendations given in the paper are taken into an account.
