Wuwei Mobile TD-LTE Network Coverage Optimization Engineering Practice

With the development of the times, the demand for mobile communication has not only limited to the traditional voice business, the new mobile Internet business has become the darling of the new era, but also produced a huge amount of data transmission needs of the traditional wireless network load capacity to form a strong challenge. TD-LTE(Time Division Long Term Evolution) is in order to meet the needs of the rapid growth of users, to meet the challenges of foreign advanced communications technology, led by China and has a core independent intellectual property rights of a LTE(Long Term Evolution) international standards.The TD-LTE is a new generation of broadband mobile communication technology, is dominated by China, and has the characteristics of "globalization" of standards. The TD-LTE has independent intellectual property rights in China, it compared the TD-SCDMA(Time Division-Synchronous Code Division Multiple Access) technology, in the inheritance and development of the advantages of TD-SCDMA at the same time, is the introduction of MIMO(multiple input multiple output) and OFDM(orthogonal frequency division multiplexing) technology. The TD-LTE has rate quickly, time delay is very low and high frequency spectrum utilization is very significant advantages, these advantages make most of the operators in very limited spectrum bandwidth resources to produce even more powerful business supply ability, and this is exactly what the international mobile communication industry coveted goal.The TD-LTE network optimization mainly includes coverage optimization, interference and adjacent regions optimization and system parameter optimization, etc.Firstly, the basic concepts and technical features of TD-LTE are introduced, introduces the TD-LTE system the two key technologies of OFDM technology and MIMO schemes, and for the TD- LTE networks in the global and domestic commercial situation has carried on the simple description. Then introduces the TD-LTE system gave an overview of the network coverage optimization at the same time. For TD-LTE system, TD-LTE and the similarities and differences between TD-SCDMA wireless network optimization are introduced, and on the TD-LTE network optimization guiding ideology, principles, covered optimizing content, means and methods were introduced. Then of Wuwei mobile TD-LTE network structure and the existence question has carried on the earnest analysis, and aimed at these problems puts forward the wireless optimization target, emphasis and steps. Finally, illustrates several Wuwei mobile TD-LTE network optimization of engineering practice case, through the wireless connection rate, drop rate, success rate, etc. According to the analysis of the key indicators, concluded that Wuwei mobile TD-LTE index has a certain degree of improvement.Through specific engineering practice, can deepen to the TD-LTE wireless network optimization work and further understanding of the whole system.
