Requirements for area coverage probability
Area of coverage target areas
Note: 1. Determine the coverage target service type for different services in different areas(whether requiring continuous coverage and coverage probability requirement. The above servicetypes should be adjusted based on field situations). 2. Whether requiring indoor coverage or not. 3.For coverage probability value, refer to solutions.
