面向城市管理的政务物联数据专网规划设计

通过研究城市管理中各级政府及委办局的实际需求,以北京市有线政务专网为依托,规划了面向城市管理的政务物联数据专网的体系结构,为北京城市管理提供了一个稳定可靠的数据专网.该专网通过比较各种无线数据通讯技术主要包括3G技术和4G技术,最终选择采用TD-LTE技术,并根据TD-LTE技术特点及北京城市管理特点设计了专网网络覆盖目标.结果表明:通过对比分析不同频率、不同方式下的测试结果和仿真数据进行了网络性能和容量等设计,实现一个网络性能最优和网络覆盖最节约的面向城市管理的政务物联数据专网的规划设计.

Urban Management Planning and Design of E-government IOT Data Networks

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.
