The WHO states: “From all evidence accumulated so far, no adverse short- or long-term health effects have been shown to occur from the RF signals produced by base stations. ” (WHO fact sheet “Base stations and wireless technologies”). But the actual EMFs emitted from different sources can vary greatly, and the distances needed to reach a desired “safety level” are difficult to predict. For more accurate safety distances, on-site measurements with appropriate test meters are strongly advised. The guidelines below are the minimum. . Primary antennas for transmitting wireless telephone service, including cellular and personal communications service (PCS), are usually located outdoors on towers and other elevated structures like rooftops, water tanks and sides of buildings. The test wind speed is 15 km/h. Why do wireless. . Horizontal Clearance? Vertical Clearance? Overall Clearance? .

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.
How much RF exposure should a cell site transmitter have?
In the case of cellular and PCS cell site transmitters, the FCC's RF exposure guidelines recommend a maximum permissible exposure level to the general public of approximately 580 microwatts per square centimeter.
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.
What happens if a PCs transmitter is near a cellular antenna?
As with all forms of electromagnetic energy, the power density from a cellular or PCS transmitter rapidly decreases as distance from the antenna increases. Consequently, normal ground-level exposure is much less than the exposure that might be encountered if one were very close to the antenna and in its main transmitted beam.

Why is wind power a problem in telecommunications?
Wind power is one of the fastest-growing technologies for renewable energy generation. Unfortunately, in the recent years some cases of degradation on certain telecommunication systems have arisen due to the presence of wind farms, and expensive and technically complex corrective measurements have been needed.
Why do off-grid telecommunication base stations need generators?
As the incessant demand for wireless communication grows, off-grid telecommunication base station sites continue to be introduced around the globe. In rural or remote areas, where power from the grid is unavailable or unreliable, these cell sites require generator sets to provide power security as prime power or backup standby power.
In the communication power supply field, base station interruptions may occur due to sudden natural disasters or unstable power supplies.
