Research On The Application Of TD-LTE

This paper is about research on the application of TD-LTE private network.Facing the existing problems during process in private network,in this paper,we put forward the concrete solution of TD-LTE application in power communication business scenario by studing Intelligent Power Private Communication Network and key technology of TD-LTE.At first,the problems of the Smart Grid were analyzed,and the key technologies of TD-LTE were introduced.Then the theoretical solution under the electric power communication business scenario have been put forward in detail,and this paper parsed the electric business requirements.Research has been done of LTE230 and LTE1800 communication system in technical characteristics,bandwidth and rate requirements,coverage area,business types of electric private network and investment cost.At last,analyzed the coverage model for studying the coverage area and coverage performance indecators under different modulation mode.Then,the simulation experiments were carried out,the simulation parameters were set according to special scenario.The technical scheme is validated of coverage prediction and capacity simulation about LTE230 and LTE1800,and the rendering results have been given,along with supportion of different power distribution and power users.At the end of this paper,the simulation results were analyzed to illustrate the availability and advantages of TD-LTE communication system applid in electric power network.
