Cellular (cell) phones first became widely available in the United States in the 1990s, but since then their use has increased dramatically. The widespread use of cell phones has led to cell phone towers being placed in many communities. These towers, also called base stations, have electronic equipment and antennas that receive and transmit radiofrequency (RF) signals.
How do cellular phone towers work?

The antennas need to be high enough to adequately cover the area. Base stations are usually from 50-200 feet high. Cell phones communicate with nearby cell towers mainly through radiofrequency (RF) waves, a form of energy in the
