Efficiency of RF Energy Harvesting in Modern Wireless Technologies

P. 110–118.

Sviatoslav Iakimenko, Ikonnikova D.

The paper investigates the effectiveness of wireless power collection of electromagnetic energy emitted by LPD433 and Wi-Fi transmitters as well as by the base stations of the LTE and 5G mobile network. The legal regulations of the Russian Federation that affect wireless energy collection (sanitary zone range, maximum transmitter power and antenna gain, etc.) have been taken into consideration. The efficiency of options for wireless energy collection at various free and cellular frequencies has been compared according to such parameters as collected power, maximum charging range and energy replenishment coefficient. Based on the results of the comparison, the most promising RF bands which can be used for wireless harvesting in Russia have been proposed.
