In our daily life, electromagnetic waves are everywhere. Excessive electromagnetic radiation from wireless communication terminals can have certain impacts on human health. Long-term exposure to electromagnetic radiation can cause fatigue and other symptoms. Therefore, governments and telecommunications regulatory agencies in various countries have issued corresponding regulations on electromagnetic radiation.
