摘　　要：针对移动通信信号覆盖的特点和实际情况,对平原、山区和市区的信号覆盖进行了分析。平原信号较弱的地区,需要延伸覆盖,公路及其附近地区可交替设站。山区主要考虑用尽量少的基站去覆盖。市区覆盖要降低干扰,处理好高层建筑和地下室的覆盖。对信号覆盖进行了数学分析,形成了矩形数学覆盖系统和物理覆盖网格,选择了覆盖权函数。According to the characteristics and actual situation of mobile communications coverage, the signal coverage in plains, mountains and urban area is mathematically analyzed. In plain areas with weak signal, the coverage needs to be extended while in the areas nearby highways the base stations may be alternately set up. Less base stations are considered for coverage of mountain areas. Interference should be reduced in coverage, and coverage should be properly handled in high buildings and basement. By the mathematical ana of signal coverage, a rectangle covering system and mathematical physics coverage grid are formed and the wei urban lysis ghtedcoverage function is chosen.
