Abstract

Study of the Electromagnetic Field Generated by Wireless Communication Systems S. Andreica, C. Munteanu, M. Gliga, C. Pacurar, A. Giurgiuman, C. Constantinescu. Study of the Electromagnetic Field Generated by Wireless Communication Systems. 2022 International Conference and Exposition on Electrical and Power Engineering (EPE), 2022, pp. 218-222, doi: 10.1109/EPE56121.2022.9959779. Abstract The aim of this paper is to outline the issue of exposure to electromagnetic radiation from communication systems (wireless routers, mobile phones) and to assess the intensity of the electric field to meet the levels within the limits imposed by law. The theme is a topical one because we use and are close to these devices every day, being exposed to the electromagnetic field both those who use the equipment and those who are close to it, lately this field being more and more publicized with the technological progress. Two generations of wireless routers were analyzed tracking electromagnetic field emissions depending on the position and number of users, this being done for mobile phones. A receiver microstrip antenna was also implemented to compare the results. The results obtained by experimental measurements, numerical modeling is presented and analyzed in this paper. Conclusions The values of the electric field intensity increase when we connect several devices, when we approach the field generator but also when we are at the level of the antennas of the wireless router. It is observed that the values of the electric field intensity do not exceed the limit of short-term exposure (61V/m). The highest value measured by us is 3.71 V/m for SMP2 positioning at, 0.1 m from the wireless router and at a height of 0.8 m from the ground, with two laptops connected to the wireless router from generation 4. However, this value exceeds the limit of 0.6 V m at long-term exposure. Following the analyzed studies, it is recommended to position the communication devices as far away from the human body as possible, in the case of the wireless router to position it in more isolated areas. Comparing the results obtained for the two types of antennas, it can be stated that the antenna implementation was successful due to its functionality as a wireless antenna using it as a receiver, at a frequency of 2.4 GHz, together with the spectral analyzer. Comparing the results obtained with the microstrip antenna with those obtained with the telescopic antenna we can say that the results are similar. ieeexplore.ieee.org

Main findings

Experimental measurements and numerical modeling assessed electric field intensity from wireless routers and mobile phones as a function of distance, antenna height, and number of connected devices/users. Electric field intensity increased with more connected devices, closer distance to the source, and being at antenna level; measured values did not exceed the stated short-term limit (61 V/m), with a highest reported value of 3.71 V/m at 0.1 m from a generation-4 router (two laptops connected), but this exceeded the stated long-term limit of 0.6 V/m.

Outcomes measured
