Cell Phone base stations may be free standing towers or mounted on existing structures , such as tress , water tanks, or tall building. the antennas need to be located high enough so they can adequately cover the area base stations usually range in height from 50 -- 200 feet.
Cell phones communicate with nearby cell towers mainly through radio frequency(RF) waves , a form of energy in the electromagnetic spectrum between FM radio waves & microwaves . Like FM radio waves , microwaves, visible light & heat , they are forms of non-ionizing radiation. This means they can not cause cancer directly damaging DNA, RF waves are different from stronger types of radiation such as x-rays , gamma rays , & ultra violet (UV) light, which can break the chemical bonds in DNA.
At very high levels , RF waves can heat up body tissues when a persons makes a cell phone call a signal is sent from the phone's antenna to the nearest
base station antenna. The base station responds to this signal by assigning it an available radio frequency channel. RF waves transfer the voice information to the base station. The voice signals are then sent to a switching center , which transfers the call to its destination. Voice signals are then relayed back & forth during the call.
