Based on the actual demands of the government of all levels, and depending on the private network of Beijing cable E-government, a city management oriented system structure is designed, which provides a stable and reliable private data network for the city management of Beijing. In this private network, TD-LTE technique is adopted on the private network construction by comparing the pseudo distance wireless data communication technology including 3G and 4G. Moreover, the coverage target of the private network is also designed according to the technical and city management characteristics. Finally, different test results and simulation data under different frequencies and modes are analyzed to conduct the design on the performance and capacity of the network, which realize the design of city management oriented E-government private network with the optimal performance and the most economical network coverage.
