TD—LTE室内分布系统建设策略

随着移动通信建设步伐的不断加快以及移动用户的飞速扩大，大中城市的室外区域已经基本做到无缝覆盖。为高速数据业务提供稳定、高质量的无线信号，提升用户感知，增强用户依赖性，室内覆盖分布系统建设已成为解决网络深度覆盖的重点手段。根据NTTDoCoMo的统计数据，手机用户70％以上的话务需求发生在室内，加上对TD-LTE高速数据业务的定位，要求信号质量较高；因此，该技术在未来中国移动网络建设中，将承担越来越重要的角色。本文深入研究分析了TD-LTE室内分布系统建设思路、具体性能特点和部署策略，对TD-LTE网络建设意义重大。

Strategy of TD-LTE Indoor Distributed System Construction

with the development of mobile communications construction pace accelerate endlessly, of mobile users fleetly increase in large and medium-sized city outdoor area, seamless coverage has been basically achieved. To improve the stability of high speed data business, high quality wireless signal, and enhance the user perception and the user stickiness, indoor coverage distribution system construction has become the key means to solve network depth of coverage. According to NTT DoCoMo data, more than 70% of mobile phone user demands occurred in the interior, plus TD-LTE high-speed data busi- ness orientation to the signal of high quality, the technology will plays a more and more important role in future China mo- bile network construction. In this paper, the paper deeply researched and analyzed TD-LTE indoor distributed system builds train of thought, specific performance characteristics and deployment strategies, which is great significance to the TD-LTE network construction.
