3.4.7.1 Pole Grounding
Pole grounding aims to protect the equipment as much as possible from potential damage from lightning
overvoltage. However, the interfaces between the gNB and the outside world mainly include a power
system, grounding system, antenna feeder and lightning receiving device, and signal line. Therefore, any
damage caused by lightning primarily comes from the voltage difference between the equipment in the
gNB and one or more of the four interfaces. The pole grounding is shown in Figure 3-20.
