Network is popular in recent year. Wifi is more important to people. Therefore, we need a lot of consideration for setting the base station location. We discuss and analysis energy consumption optimization of setting indoor base station in this study. The original model is a mixed integer nonlinear programming(MINLP). It is an NP-hard problem. We should make linear relaxation on it than we can solve it. We use approximation method of log term and piecewise-RLT(Reformulation Linearization Technique) to make all constraints converted from nonlinear to linear. The model is simplified to mixed integer linear programming(MILP). Then we use branch-and-cut algorithm and CPLEX software to solve the problem. Finally, we get the original problem optimal solution.
