Radio base stations
RF exposure from radio base stations
Base stations are needed for transmitting and receiving radio frequency (RF) signals to and from mobile telephones. The base station antennas are often placed high on a house roof or on a mast, to be able to cover a wide area. Since the number of mobile phone users is growing, more base stations are needed.
The maximum output power level varies from a few watts in urban areas up to about 100 watts for base stations in rural areas.
The intensity of radio waves is drastically reduced with increasing distance from a base station antenna. When less than a few meters away from a typical outdoor antenna, the radio wave exposure is below the recommended limits.
