The Research And Software Implementation For TD-LTE Capacity

There are many problems in traditional power wireless network,such as low security,small number of frequency points,limited transmission capacity,which hinder development of the power wireless private network.While the electricity network is developing fast,the cellular mobile communications network also made a remarkable leap.As the fourth generation communication standard,TD-LTE has many technical features,including carrier aggregation,time division duplex,flexible slot configuration,effective support for asymmetric traffic and so on.And TD-LTE has made large-scale application in a cellular network.Therefore,TD-LTE technology is very suitable for requirements of power wireless private network.As a very important issue in the mobile communication,network planning can evaluate network performance.For one side,it can make the network more reasonable;for the other side,it can greatly reduce the complexity of the network's subsequent expansion and optimization.Electricity network is also inseparable from network planning,and it's different from cellular network in network planning.This paper mainly introduces research on TD-LTE capacity simulation and its application in power wireless private network planning.Firstly,it designs algorithm of the TD-LTE capacity simulation.Secondly,it introduces the programming implementation of TD-LTE capacity simulation system based on the original wireless network planning platform.In order to solve the low time efficiency problem of capacity simulation for large quantity of terminal and station,the system uses multi-threaded approach to simulation.Thirdly,it analyzes the characteristic of electricity traffic in power system,and then puts forward a modeling method for power traffic.Then,it provides information and recommendations for actual construction of power wireless private network in the Pearl River Delta cities by simulation.
