Methods for outdoor lightning protection of base stations
The protection of GSM and base station towers from lightning and overvoltage is provided by integrating external lightning systems, internal lightning systems, earthing, equipotential bonding and LV surge arrester protection techniques within the framework of IEC-62305 standard.
FAQs about Methods for outdoor lightning protection of base stations
How should a lightning protection System (RBS) be formed?
The earthing network of an RBS should be formed by a ring loop surrounding the tower, equipment room and fence, at a minimum. The mean radius re of this ring loop should be not less than l1, as indicated in Figure 1 and this value depends on the lightning protection system (LPS) class and on the soil resistivity.
Are rooftop antennas protected from lightning strikes?
If the antenna is installed on the rooftop, e.g., antenna positions 2 of Figure 29, depending on the relative height of building and the installation of the antenna system, it may be considered to be inherently protected from direct lightning strikes or be impacted by or exposed to direct lightning strikes.
What is a lightning protection system (LPS)?
3.2.3 lightning protection system (LPS): Complete system used to reduce physical damage due to lightning flashes to a structure. NOTE – An LPS consists of both external and internal lightning protection system.
How to protect the navigation light system in the equipment room?
Figure 12 shows protection of the navigation light system in the equipment room. If the NL has internal control circuits or it is based on LED technology, then an SPD is required on the top of the tower to protect the lamp. This SPD can be integrated into the lamp box.
Is a telecommunication tower impacted by lightning?
If the antenna is installed on the top of telecommunication tower, e.g., antenna positions 1 of Figure 29, it is considered to be impacted by or exposed to direct lightning strikes. Refer to [IEC 62305-3] for detail information about the protection angles and volume protected by an air termination system.
How do you measure earthing resistance in a wireless base station?
In the earthing system for a single wireless base station, the earthing network, down-conductors and metal conductors make a test loop. By using a clamp meter, the earthing resistance of the entire loop can be measured, but not the earthing resistance of the earthing network.

Are outdoor base stations safe
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.
FAQs about Are outdoor base stations safe
Are base stations harmful?
This holds true whether the base station is part of a 2G (GSM), a 3G, a 4G (LTE) or a 5G network. 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”)
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 high should a cell base station be?
“As a general guideline, cell base stations should not be located less than 1500 ft from the population, and at a height of about 150 ft.” (Levitt 2010)
How far from a mobile phone base station is RF exposure?
The study “Radiofrequency radiation from nearby mobile phone base stations-a case comparison of one low and one high exposure apartment “ published in Oncology Letters (Koppel et al 2019) found that the apartment with high RF exposure had outdoor areas as close as 6 meters (about 19.6 feet) from the cell antenna array.
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.
Can unauthorized people access a base station?
The antennas are installed in such a way that unauthorized people do not have access to the area where the limits may be exceeded. This holds true whether the base station is part of a 2G (GSM), a 3G, a 4G (LTE) or a 5G network.
