Abstract

This chapter first makes a case about the importance of the metrology for mMIMO when it comes to RF exposure in order to provide meaningful data for the regulatory bodies so they can, in turn, make informed and sensible decisions on how to set exposure limits for 5G BS. It then describes some of the existing works on the topic and focus in more details on experimental work. It then explains the way forward that are currently taken to define how to measure and regulate the RF-exposure of 5G BS, by mainly using statistical approaches to better reflect the beamforming nature of the mMIMO transmission. Statistical models based on simple theory and system level simulations have first been proposed, before data from real 5G BS has been acquired to confirm the results of these models. The main finding being that using statistical approaches for defining the exclusion zone of 5G BS seems reasonable in comparison with the traditional method, which create unrealistically large exclusion zones.
