What causes a communication base station to fail?

Power interruption is a significant contributor to communication base station functional failure. Communication systems closely rely on power systems, and power outages can result in widespread station interruptions. In the case of the earthquake in Changning County, 90% of disrupted base stations experienced power interruptions as the cause .

What causes base station functional failure?

In Fig. 6, the causes of base station functional failure (T) are identified: power interruption (I 1), damage to communication room (I 2) (equipment included), and damage to communication towers (I 3).

How important is wireless service during a power outage?

For both communication and information, wireless service during a power outage is incredibly important. This story is part of Road Trip 2020, CNET's series on how we're preparing now for what could come next. It's wildfire season again in California as the second and third largest blazes in the state's history continue to burn.

How does a communication tower damage a base station?

The communication tower and its antenna equipment are responsible for signal transmission and reception, and their damage directly affects the normal operation of the base station. This study mainly considers tower body damage (X 11) and antenna damage (X 12).

What type of damage does a communication base station suffer?

Based on field investigations after the Yangbi earthquake , this paper categorizes typical seismic damage of communication base stations as follows: Communication infrastructure damage is particularly severe, with building collapse leading to equipment destruction.

Do communication base stations perform post-earthquake functionality using Bayesian network?

A method to evaluate the post-earthquake functionality of communication base stations using Bayesian network is developed. The dependence between the equipment and its hosting building structure, and the impact of power outages are considered. The method is validated using seismic damage data from the Ludian Earthquake.
