Long-term Network-based Assessment of the Actual Output Power of Base Stations in a 5G Network | Semantic Scholar (2024)

Downlink output power distributions for radio base stations in 2G and 3G mobile communication networks have been assessed using data collected from the Operations Support System, which normally is used for network monitoring and management.

Downlink output power distributions for RBSs in a 4G LTE mobile communication network have been determined by extracting data using the operations support system of the network and it was found that the actual output power levels are significantly below the theoretical maximum.

Results on output power level distributions of radio base stations (RBSs) and user devices connected to a wideband code division multiple access-based third generation (3G) mobile communication network in India are presented and related to realistic human exposure to radio frequency (RF) electromagnetic field (EMF) emitted by the corresponding RBSs and the devices.

The three dimensional spatial channel model standardized by the Third Generation Partnership Project is proposed in order to assess reasonably foreseeable compliance boundaries of massive MIMO BSs and shows that the statistical approach developed in this paper allows reducing to nearly half the compliance distance when compared to the traditional method.

Measurements of the 6-minute time-averaged EMF levels in front of a mMIMO antenna operating in a 4G LTE time division duplex (TDD) network and compare results with conservatively computed EMf levels are reported on.

This work determines duty factors for UMTS from the data of 37 base stations in the Swisscom network based on simple approximations and gives a lower limit for LTE estimated from the base load on the signalling channels.

ICNIRP has updated the radiofrequency EMF part of the 1998 Guidelines, which provide protection for humans from exposure to EMFs from 100 kHz to 300 GHz.
