Design And Application Of TD-LTE NanoCell Network

As the technology upgrading and Large-scale used, the TD-LTE, with China’s independent intellectual property rights, become more and more mature, which marks the arrival of mobile broadband era. Compared with 3G technology, TD-LTE technology make substantial improvement in terms of the peak rate, average throughput, and delay or end to end network performance. However, with the TD-LTE into commercial, Network quality requirements are getting higher and higher. According to industry statistics, the mobile phone business, especially data services mostly in the interior. However, due to the problems like, hardly construction of traditional indoor distribution and construction department often cannot fully guarantee the quality of passive components and auxiliary materials such as cables; as well as Monitoring and management difficulties and system integration issue, which all make very difficult to ensure coverage and user experience feelings. And at the same time, Wi-Fi popularity has a great impact on revenue of the operator’s 4G business. How can not only ensure TD-LTE service quality and user experience, but also ensures that the operator benefits, and also can reduce operators’ construction, operation and maintenance costs, it’s still need new coverage solution to resolve.NanoCell indoor sub-scale network coverage solution could overcome the above problems, improve the efficiency and quality of TD-LTE construction, so as to enabling rapid, high-quality network construction.NanoCell equipment, because its system is different from a conventional base station, which only using ordinary home network can achieve data backhaul network, Coupled with features as the plug and play, low cost, etc., it can be complementary with the macro network at the beginning of building network, make good coverage where microcell hardly reach, rapidly provide TD-LTE service, meet network requirements and also save investments; while in scale networking, NanoCell could offload macro stations traffic pressures, resolve macrocell difficult problems such as intensive user area or weak coverage areas, etc.With the official commercial TD-LTE, a large number of TD-LTE network need to set up, how to effectively scale coverage with TD-LTE network by NanoCell, to solve the difficult problems in traditional coverage method, it’s need to do research on TD-LTE system covers. In this paper, this research, the main contents are as follows:1. Introduce TD-LTE principle, the principle of adaptive coding and switching technology related to the scale networking, technologies and principles of NanoCell, and NanoCell scale networking.2. Introduce design principle of wireless coverage, design the required test application environment, include Scenarios assessment, link calculations, site selection and parameter planning. On this basis, design the solution of the pilot applications, equipment installation, application content and application validation processes.3. According networking applications solution, Verify the equipment business functionality and performance in scale networking. Also cover issue that how to make corresponding test of system coverage performance in the spot environment, and analysis the test results.At last, summaries the features of NanoCell scale networking solutions on the article.
