As a supplementary part of outdoor macro station coverage

community coverage has always been an important way to solve the deep coverage of residential areas.In recent years

limited by the problems of investment and owners’communication

after trying to arrange antenna points for lawn lamps and indoor points

it has been proved to be the best way to use inter building fighting

which has become the main construction mode of residential area coverage.In this paper

according to the daily antenna setting method in cell coverage

an automatic algorithm is proposed to determine the number of antennas and dip angle setting.The algorithm can not only correct the existing scheme

but also provide a basis for designers in the subsequent construction.
