At the 2026 IEEE International Symposium on Measurement in Networking and Communications in Naples, three separate research groups reported that conventional worst-case methods, including the CEI EN IEC 62232 standard formula, significantly overestimate realistic 5G and MaMIMO base-station exposure. Long-term measurements on commercial 4G and 5G NR networks (Galati et al.), power-reduction factors measured on urban and rural 5G mMIMO base stations (Valbonesi et al.) and 3700 MHz field trials of the IEC 62232 formula (Notari et al.) all point the same way. Simpler alternatives, such as the zero-span measurement technique in the Italian SNPA Guidelines, held up in the reported test conditions.
Note: MNC 2026, held in Naples from 13 to 16 July 2026, is the measurement symposium of the IEEE Instrumentation and Measurement Society's technical committee on measurements and networking, running since 2011 and listing human exposure to electromagnetic fields among its topics; the symposium site and the full technical programme (PDF) are public.

"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)
