(D) Total emissions of major pollutants (CO 2, NOₓ, SO 2, and PM 2.5) generated by the electricity consumption of communication base stations before and after the upgrade. Paired bars with the same color represent pre- and post-upgrade comparisons for the same pollutant. Emissions of all pollutants are significantly reduced after the upgrade.
The average distance between neighboring communication base stations changed from 0.846 to 0.920 km after some communication base stations were closed at night. When a base station is shut down, its communication load is taken over by other neighboring base stations within the same base station unit.
While ignoring that the damage of the post-earthquake communication base station is also related to many factors such as the geographical location of the base station, the distance from the earthquake source, the geography and geology between the earthquake source and the communication base station.
The weight parameters of two-parameter set by the actual field data significantly show that the failure of base stations after earthquake is mainly due to the geological differences where the base stations are located.
As expected, terrestrial base stations cover mostly segments with high bandwidth requirements in the centre of critical areas, while the aerial base stations provide bandwidth at the coverage gaps.
