A Preliminary Investigation of EMF Exposure from Access Points in a Distributed MIMO System

Distributed multi-input multi-output (D-MIMO) is one of the most promising technology candidates for 6G infrastructure. When the access points (APs) of the D-MIMO network are placed sufficiently close, the cumulative electromagnetic field (EMF) exposure might differ significantly from the EMF exposure of a single AP. In this paper, a simple approach is proposed to assess EMF exposure using the standalone AP and a correction factor. Good agreement is obtained using simulation results. It is expected that for large AP separation distances, e.g., a few meters and above, the EMF contribution from adjacent APs might be considered negligible (less than 1 dB and even lower).
