At the 2026 IEEE International Symposium on Measurement in Networking and Communications in Naples, three separate research groups reported that conventional worst-case methodologies, including the CEI EN IEC 62232 standard formula, significantly overestimate realistic 5G and MaMIMO base-station exposure. Long-term measurements on 4G and 5G NR commercial networks (Galati et al.), a comparison of scalar, semi-vectorial, and vectorial power-reduction factors on operational urban and rural 5G mMIMO base stations (Valbonesi et al.), and 3700 MHz field trials of the IEC 62232 extrapolation formula (Notari et al.) all point the same direction. The standard's conservative extrapolation does not match measured reality, and simpler alternatives, such as the zero-span measurement technique used in the Italian SNPA Guidelines and scalar FPR conversion, hold up well in the reported test conditions.

"currently standardized extrapolation approaches may significantly overestimate realistic exposure levels"

— Galati et al., 2026 IEEE International Symposium on Measurement in Networking and Communications (MNC)

"Conventional worst-case methodologies based on static antenna patterns significantly overestimate realistic exposure levels."

— Valbonesi et al., 2026 IEEE International Symposium on Measurement in Networking and Communications (MNC)

"To overcome the encountered difficulties, the study confirms the validity of an alternative approach, based on the zero-span measurement technique during traffic forcing, which is included among the methodologies proposed in the Italian SNPA Guidelines."

— Notari et al., 2026 IEEE International Symposium on Measurement in Networking and Communications (MNC)
