Comparison of networking technology in relationship with cellular phone radiation as a potential threat to the population

Abstract

Objective: Detection real absolute value of electric intensity (E) of electromagnetic field (EMF) generated from a mobile cell phone at 2G, 3G, 4G and local Wi-Fi networks for voice telephony and data transmission in the working environment. Methods: A total number of measurements was n= 225 in three different interior places. Measurements were realized by broadband sensor NARDA 550 at a frequency range of antenna 100 kHz - 3GHz. The time for one measurement was 6 min. The measured data were compared with the limit values of the Decree No. 534/2007 of Slovak Republic. Conclusion: The results showed that voice telephony in 3G network exhibited lower E of EMF than in 2G network. A comparison of data transmission showed that both 3G and 4G networks had a higher level of E EMF compared to the local Wi-Fi network. Limit values E EMF valid for the Slovak republic were not exceeded by any networking technology in all measured places.
