Due to the problems in the planning of electric power wireless communication

and in order to serve the smart grid better and carry out the application of time division long term evolution(TD-LTE)technology in the power communication fields and other fields

a high reliability planning method with low self-interference in power wireless special network is proposed. It improves the survival ability of user service when the base station or the terminal return network is out of order by using the overlapping coverage of base station signals. The overlapping cells are merged to avoid the same frequency interference. By optimizing the organization deployment of the base station and in the case of the same number of base stations

the average inter station distance of overlapping coverage increases

and the network reliability is improved on the premise of ensuring network performance. The scheme solves the mutual interference of the same frequency caused by the overlapping coverage between the base stations of the existing technology. It also solves the problems of the frequency resource constraints

which may be unable to implement the different frequency overlapping coverage.
