Abstract : Nowdays, the base stations and antennas become more and more complicated, which makes the choice of base station location of communication network more and more complicated, and needs to solve the weak coverage problem of the existing network. In this paper, data preprocessing is firstly carried out, base station distance threshold is selected as the constraint condition, base station site model is established, site selection is carried out, and three sector main direction angles of each base station are determined according to the sector direction and coverage traffic constraints between the selected base stations. The simulated annealing algorithm based on 0-1 planning was used to solve the 2500×2500 candidate region iteratively, and finally the optimal coordinates and the optimal principal direction angle of the new macro base station and micro base station were obtained.
