Measurements and Analysis of Temporal and Spatial Variability of WiFi Exposure Levels in the 2.4 GHz Frequency Band

[EN] This paper presents an evaluation of the WiFi exposure levels inside the university in the 2.4 GHz frequency band. The selected environment is the typical scenario where WiFi exposure concerns have increased in the last years, since a Wireless Local Area Network is deployed close to the users....

The selected environment is the typical scenario where WiFi exposure concerns have increased in the last years, since a Wireless Local Area Network is deployed close to the users. Measurements of 1 h and 24 h duration were performed to assess the temporal and spatial variability of the signal. Two instruments were employed, a spectrum analyzer appropriate configured for recording accurate and realistic samples and an exposimeter. A detailed description of the equipment, the measurement procedure and data analysis is provided in order to allow the reproducibility of these types of measurements. Finally, a comparison of the WiFi levels obtained by other authors is presented, concluding that all these methods are useful for determining WiFi exposure distribution, but if more accurate results are required, professional equipment appropriately configured should be used.This work has been financially supported by the Basque Government (IT1234-19), by the University of the Basque Country UPV/EHU under Grant Dokberri 2018-II (DOCREC18/36), and by the Spanish Government under the grant RTI2018-099162-B-I00 (MCIU/AEI/FEDER, UE).Elsevier202420242019info:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10810/65663reponame:Addi.
