Monitoring of RF-Field Strength in the Environment by Mobile Telecommunications in the Moscow

The growing popularity and use of the wireless Internet of Things and cyber-physical systems increase the demand for "green" technologies in the field of mobile telecommunications. To be completely wireless, such devices need an integrated RF energy harvesting system that ensures efficient recharging of the batteries and accumulators used in them. This article provides an assessment of the coverage areas of mobile operators in Moscow and the Moscow region by the frequency ranges used, taking into account the power distribution. An experimental study of the RF-field strength of telecommunication equipment was carried out using a log periodic antenna (KM6-600/6000) with linear polarization and a portable spectrum analyzer with an Arinst SSA-TG R2 tracking generator. The results of attenuation of electromagnetic waves of GSM and Wi-Fi bands under various environmental conditions are obtained, which is of interest for the development of effective intelligent harvesting systems.
