Mathematical Investigation and Analysis of Regional Signal Coverage in Mobile Communication

According to the characteristics and actual conditions of signal coverage, coverage is analyzed in different regions such as plains, mountains and urban areas. Signal is weak in plain, which needs to extend coverage. Stations can be alternately erected in roads and their surrounding areas. The signal being covered in mountain area with less base stations is considered. Interference of urban coverage should be reduced and coverage between the high-rise building and the basement properly handled. Coverage of the signal is mathematically analyzed, and the rectangular mathematical coverage system and physical coverage grid are formed. The coverage functions are selected after the shape of coverage is determined. In the process of displacement coverage of effective mobile signal, the displacement function of the physical coverage is deduced. The entire first and second order approximations are carried out on constant function during physical coverage.
