It has been years that scholars argue over whether cell phone radiation is harmful to human body. Now more and more research indicates that the cell phone radiation can destroy human cells and the DNA carrying human genetic information. As a result
the intake of cell phone radiation over a certain level will lead to negative effects on human body. Seeing that 3G mobile communications systems
respectively WCDMA
cdma 2000 and TD-SCDMA
are adopting various technologies
the cell phone of each mode differentiates remarkably in the volume of generated radiation while being used. In this regard
the article uses link budget
through a quantitive approach
to compare the three types of cell phones and concludes which is “greener” in real use.
