Beamforming and Population Exposure: 5G NR Measurement Methodologies Applied to LTE AAS

This work presents the results of a measurement campaign conducted on an LTE Active Antenna System (AAS) aimed at defining effective operational procedures for determining the maximum exposure generated by such systems. Four distinct scenarios, in which data traffic conditions were varied using three mobile terminals that allowed for saturating the signal frame, were defined. For this reason, it is possible to apply an exposure assessment procedure to LTE AAS similar to that proposed for 5G NR systems, namely based on forcing data traffic towards the receiving antenna and measuring the corresponding received power.
