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.
