Single User EMF Exposure Assessment in a Case of Incoming 5G Indoor Scenario

The aim of the present paper is to assess the exposure levels to electromagnetic field taking account the innovative aspects that the incoming 5G networks will introduce. The incoming 5G networks will in fact utilize mm-wave spectrum coupled with MIMO base station and beamforming techniques. These innovations will be deployed both in outdoor and indoor areas and will permit to improve services and benefits for all the population, but will also drastically change the exposure levels of the population to RF-EMF. A promptly adequate exposure assessment is thus necessary. For this reason, in this work, a specific case of a 5G exposure scenario in indoor environment is evaluated. More in details, the exposure levels caused by an 8x8 indoor planar array antenna at 3.7 GHz, which simulates the presence of an indoor access point, are here analyzed in a human computational model. Three different worst-case configurations are evaluated by making use of the Sim4Life simulation platform. The analyzed quantity is the specific absorption rate for all the domain of interest and for some specific tissues. The work represents a first attempt to further expand the knowledge about the exposure levels for the incoming 5G indoor scenarios.
