Exposure assessment methods with respect to the 5G mobile communication systems

This paper describes recent activities with respect to exposure assessment method of the incident power density (PD) above 6 GHz when wireless devices such as the 5
^th
generation mobile communication system (5G) used in close proximity to the head and body. These works have been jointly done by the International Electrotechnical Committee (IEC) and the Institute of Electrical and Electronics Engineers (IEEE). Firstly, definitions of the PD are briefly introduced because there was no exact definition of the PD except in the far-field region. Then, measurement and computation procedures are introduced.
