The network coverage evaluation mainly focuses on the overall index

and the granularity of the problem is at the community level

so it is unable to achieve the accurate support of rapid geographic positioning

region planning and optimization. This paper proposes a network coverage evaluation system based on region outline

which can realize the evaluation conversion from point to area

from the community level to the regional level

provide direct guidance for timely input of resources and effective improvement of network performance in the hot spot areas.
