Until now there were other trying such as magnetic induction, microwaves and lasers. The last challenge of Japanese researchers is to use a radio frequency signal to transmit power. Masahiro Hanazawa from Toyota Central R&D Labs and Takashi Ohira art Toyohashi University […]

These standards were based on research from experiments on animals and cells being based on the whole body average […]

They are consistent part of a growing number of people who produce a reaction to electromagnetic pollution. Long highlighted as a problem by environmentalists and sufferers, such reactions are still largely ignored or seen as exaggerated. However, exposure to electromagnetic fields and the radio […]

The combination of antenna towers and associated electronic equipment is referred to as a “cellular or PCS cell sites” or “base station.” Cellular or PCS […]

To understand these challenges, a few comments about radio frequency measurement are required. Protocols for the measurement of radio frequency energy for the purpose of human exposure assessment often recommend the use of an “isotropic broadband […]
