First selective sensor implemented in EMF RATEL system

03.10.2018

RATEL has continued to develop its EMF RATEL system for continuous monitoring of electromagnetic field levels. A selective sensor, integrated into the sensor network built at the end of 2017, was mounted onto the roof of the elementary school „Drinka Pavlović“ in Belgrade. The school is situated in the center of Belgrade and is surrounded by different sources of electromagnetic fields, thus representing a facility of interest, as defined in the Rulebook on sources of non-ionizing radiation of special interest, source type, manner and period of their examination („Official Gazette of RS“, No. 104/09).

The selective sensor measures total levels of electromagnetic fields at the location where it is mounted, including all single radio-source contributions in the school vicinity. Measurement results and measured data analyses are displayed in an interactive diagram, offering the possibility of different sub-bandwidth selection, available at : http://emf.ratel.rs/results/details/eng/15/

The sensor measures electromagnetic field levels in frequency bandwidths from 100 kHz to 6 GHz, for all technologies in the following sub-bandwidths:

87 MHz – 108 MHz – FM radio

138 MHz – 174 MHz – functional radio-links

380 MHz – 400 MHz – TETRA systems

420 MHz – 430 MHz – (CDMA) fixed wireless telephony

430 MHz – 470 MHz – functional radio-links

470 MHz – 790 MHz – digital TV (DVB-T2)

790 MHz – 821 MHz – mobile telephony 4G (800 DL)

832 MHz – 862 MHz – mobile telephony 4G (800 UL)

880 MHz – 915 MHz – mobile telephony 2G/3G (900 UL)

925 MHz – 960 MHz – mobile telephony 2G/3G (900 DL)

1710 MHz – 1785 MHz – mobile telephony 2G/4G (1800 UL)

1805 MHz – 1880 MHz – mobile telephony 2G/3G (1800 DL)

2110 MHz – 2170 MHz – mobile telephony 3G (2100 DL)

2400 MHz – 2500 MHz – short-range devices/ broadband wireless networks for data transmission

3400 MHz – 3800 MHz – mobile telephony

5200 MHz – 5800 MHz – short-range devices / broadband wireless networks for data transmission

Simple selection of several simultaneous sub-bandwidths enables comparison between different electromagnetic field source effects.
