According to the cover, the capacity, the quality requirement and the installed capacity determine each base depot the hardware and the software disposition, including sector, carrier and channel unit quantity.At present the commercial TD-SCDMA simulation software is realizes according to the static simulation principle. Carries on the system simulation on the computer using the planning software, may analyze the network under the different system parameters and the establishment network performance, determines the appropriate network design variable and the plan. The simulation uses the Datang mobile communication equipment Limited company independent development to aim at the TD-SCDMA system's wireless network planning software specially.Compared with other communications system's planning software, increased the smart antenna wave velocity size enlargement, UE links and so on direction of arrival estimate, dynamic channel assignment, time slot disposition. Under the guarantee network simulation condition and the process correct reasonable premise, then needs the question which appears to the network simulation result to carry on the judgment, discovers the base depot establishment the unreasonable factor, and makes the adjustment to it.Regarding TD-SCDMA, the different frequency indirect strength cut is indirect the strength cut performance the frequency to be more superior than, therefore looked from the network quality angle, should first use the different frequency network.
