The Design And Optimization Of TD-LTE Indoor Distribution In High-rise Building

Along with the continuous development of mobile communication technology, terminal technology of intelligent mobile, and the increase of the number of mobile user and demand for data services, mobile communication system of our country is also in update. At the end of 2013, our country began to build 4G(TD-LTE) mobile communication network with higher speeds and lower rates. With a wide variety of applications, dependence on and demand for 4G networks is growing. Therefore, we need to constantly improve the network construction of 4G indoor distributions to meet the demand of users.Indoor distribution system is an important part of the wireless network construction. A good indoor distribution system can share the business of entire network, can improve the service quality of operators, and enhance the brand value of operators. With the deployment of 4G mobile network, the construction of indoor distribution system faces many problems, such as multi-system combination, inter-system interference, double channel construction and network optimization. These are exactly the topics which discussed in this paper.In this dissertation, the author deeply discusses the construction and optimization of 4G (TD-LTE) indoor distributions, combined with design, construction and optimization of wireless network. First, this paper introduces its research background, development status home and abroad; then introduces the development of its standard, its advantages compared with 3G; introduces the basic knowledge and the technical characteristics of TD-LTE and the problems worth attention in the construction of4G indoor distributions in high-rise building. Then the paper elaborates on it, taking the indoor distribution project of a high-rise building as an example. Finally, this paper introduces the optimization of TD-LTE indoor distribution projects in high-rise building. The main goal of indoor distribution optimization is to improve the quality of coverage, including wireless signal strength, interference, switch and throughput, etc. And the problems found during the optimization process is analyzed and solved. This paper has practical and reference significance on the construction and optimization of 4G(TD-LTE) indoor distributions in high-rise building.
