Abstract

Personal exposimeter coupled to a drone as a system for measuring environmental electromagnetic fields García-Cobos FJ, Paniagua-Sánchez JM, Gordillo-Guerrero A, Marabel-Calderón C, Rufo-Pérez M, Jiménez-Barco A. Personal exposimeter coupled to a drone as a system for measuring environmental electromagnetic fields. Environ Res. 2022 Oct 6:114483. doi: 10.1016/j.envres.2022.114483. Highlights • The wireless remote controller does not alter the bands of interest. • The structure of the drone affects the measurements in a quantifiable way. • Vertical electric field profile consistent with the antenna height and downtilt. • The attenuation of a building is estimated. Abstract Personal exposimeters are currently used in studies assessing human exposure to electromagnetic fields. These devices are usually carried by an individual, but vehicles such as bicycle or car are also used. The aim of the present study was to propose a personal exposimeter attached to a drone to perform environmental radio- frequency measurements. Trials were carried out to determine whether: (i) the wireless communication between the remote controller and the drone affects the downlink mobile telephony bands by a cross-talk effect, and (ii) the structure of the drone alters the measurements of the exposimeter compared to when the meter is on a tripod. To apply this system to a real scenario, a 3D representation of the electric field in a building was obtained, and the attenuation due to the building of radiation from outside was estimated. Measurements of the electromagnetic field with this system will make it possible to monitor without risk the emissions of antennas in their close vicinity, and to validate propagation models experimentally.

Main findings

Trials assessed whether wireless communication between the drone and remote controller affects downlink mobile telephony bands via cross-talk, and whether the drone structure alters exposimeter measurements compared with a tripod. The system was applied to obtain a 3D representation of the electric field in a building and to estimate building attenuation of radiation from outside; highlights state the remote controller did not alter bands of interest and the drone structure affected measurements in a quantifiable way.
