Assessing the Electromagnetic Field Exposure of 5G Transmitters: Challenges & Solutions [* Cross-Reference *]

From a regulatory point of view, adapting assessment and validation methodologies for new 5G installations is also a complex exercise, as it will be for future generations. Most methodologies used by regulators rely on calculations or measurement approaches that are not always appropriate - leading to an overestimation of EMF levels.

This paper gives an overview of existing calculation methods to correctly estimate the EMF exposure of a 5G mobile network, and provides an analysis to select the most appropriate framework. To do so, we first describes the key definitions and concepts framing EMF exposure assessment. Then, we review the state-of-the-art assessment methods that consider 5G's key features: Massive MIMO, millimeter Wave, and precise beamforming.
