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).
Read moreWhat is frequency and why it is used?
Frequency describes the number of waves that pass a fixed place in a given amount of time . So if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 per second. If it takes 1/100 of an hour, the frequency is 100 per hour.

In physics, the term frequency refers to the number of waves that pass a fixed point in unit time . It also describes the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.
Read moreWhat is the used of a frequency band?
A radio communications signal must occupy a range of frequencies carrying most of its energy, called its bandwidth. A frequency band may represent one communication channel or be subdivided into many . Allocation of radio frequency ranges to different uses is a major function of radio spectrum allocation.
