  1. 1. Assessment of Exposure to Electromagnetic Fields from Distributed MIMO Antennas

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Frans Nyberg Zou; [2022]
    Keywords : 6G; Distributed MIMO; Electromagnetic field exposure; Hybrid simulations; 6G; Distribuerad MIMO; Exponering av elektromagnetiska fält; Hybridsimueringar;

    Abstract : Research on 6G telecommunication networks has been initiated. Among all potential technology components, the distributed multi-input multioutput (D-MIMO) technology is one of the promising enablers. Due to the new technology solutions, additional methodologies for assessment of electromagnetic field (EMF) exposure need to be developed. READ MORE
