Should RF EMF exposure be considered when adding 5G radios and antennas?
When adding 5G radios and antennas to an existing base station site, the total RF EMF exposure from all antennas and technologies (2G, 3G, 4G, and 5G) has to be considered for assessment of compliance with limits and regulations. Figure 2.
Does 5G signal exposure affect base station compliance?
This agrees with measurements done in other countries whose authors conclude that the exposure to 5G signals is limited, , , but this does not assure the base station compliance as full load situation should be considered for such assessment. It also shows that the increase in the EMF field is due to the induced data traffic.
Can broadband field probes assess 5G base stations compliance?
This paper analyzes the feasibility of assessing the 5G base stations compliance using broadband field probes and compares their performance with alternative methodologies and equipment.
What are RF EMF limits?
The RF EMF limits applicable for base stations are typically expressed in terms of power density (unit W/m 2) or electric field strength (unit V/m) levels. Figure 2 below shows the power density limits for the general public that are prescribed in many countries globally (from the ICNIRP 1998 guidelines).
