Do mobile phones need a base station?
Mobile phones and other mobile devices require a network of base stations in order to function. The base station antennas transmit and receive RF (radio frequency) signals, or radio waves, to and from mobile phones near the base station. Without these radio waves, mobile communications would not be possible.
Why do we need more base station antennas?
As the number of mobile devices in a community grows, more base stations are needed. For that reason, more antennas are needed in such crowded locations as shopping malls where there are many mobile phone users. However, the shorter the distance between base station antennas, the lower the output power of each antenna.
How much exposure can a radio base station have?
On the ground, in houses, and other places where people reside, the exposure levels from radio base stations are normally below 1 percent of the limits. Only in the close vicinity of the antennas can the exposure limits sometimes be exceeded.
Do base station antennas affect humans?
The effects are radiofrequency sickness, cancer and changes in biochemical parameters. Similar effects from RF by different sources reinforce the conclusions of this review. The objective of this work was to perform a complete review of the existing scientific literature to update the knowledge on the effects of base station antennas on humans.
