The invention discloses a station site selection method in a power wireless private network. The method is an effective and reliable method that is used for selecting a station establishment site for a remote radio unit in a power wireless private network. According to the method, two kinds of operations of branching and elimination are combined; and complexity of the operations and optimality of the scheme are taken into consideration. Especially, an elimination proportion parameter is introduced and the calculation complexity of the method can be adjusted; and thus optimization between performance improvement and complexity reduction is realized.
