An experiment conducted by the Medical Research Institute of Kanazawa Medical University found that 60GHz “millimeter-wave antennas can cause thermal injuries of varying types of levels. The thermal effects induced by millimeterwaves can apparently penetrate below the surface of the eye.”

What frequency is harmful to humans?

Scientific evidence suggests that cancer is not only linked to mobile phone radiation and that other factors also may be involved in its development. Most mobile operators use from radiofrequency waves in the range up 300 MHz to 3 GHz that can be harmful for human health (1).

What is the main problem of millimeter waves?

Generating and receiving millimeter waves is a challenge, but the biggest and most challenging factor with these high frequencies is the travelling media. Poor foliage penetration has been observed but the biggest challenges are atmospheric and free-space path loss.
