Human Exposure To Radio Frequency Fields: Guidelines For Cellular & PCS Sites Background
Primary antennas for transmitting wireless telephone service, including cellular and Personal Communications Service (PCS), are usually located outdoors on towers, water tanks, and other elevated structures like rooftops and sides of buildings. The combination of antenna towers and associated electronic equipment is referred to as a "cellular or PCS cell site" or "base station." Cellular or PCS cell site towers are typically 50-200 feet high. Antennas are usually arranged in groups of three, with one antenna in each group used to transmit signals to mobile units, and the other two antennas used to receive signals from mobile units.
At a cell site, the total radio frequency (RF) power that can be transmitted from each transmitting antenna depends on the number of radio...
