The discussion on the health risk due to RF-EMF exposure has become even more acute with the deployment of 5G mobile communication technologies which operate in the FR1 (below 7 GHz) and FR2 (above 24 GHz) frequency bands. With reference to FR2 band, skin is considered one of the main targets due the low penetration depth of EMF in this frequency range. Here we used HaCaT cells, a human...
A numerical assessment of the radio frequency (RF) electromagnetic field (EMF) exposure behind a massive multiple-input multiple-output (mMIMO) radio base station (RBS) and to the side of the RBS from the back surface is performed. The model of the antenna array contains 8 × 8 dual-polarized cavity-backed stacked patch elements and it is mounted on a box representing the RBS chassis. The RF...
