中国的三大通信运营商已经全面进入了4G时代,一线城市已经完成了覆盖,二三线城市正如火如荼的建设中。本文就对三大运营商都有的TD-LTE制式的无线网络在建网初期如何进行规划做一个基本介绍。无线网络规划主要指通过链路预算、容量估算,给出基站规模和基站配置,以满足覆盖、容量的网络性能指标。网络规划必须要达到服务区内最大程度无缝覆盖;科学预测话务分布,合理布局网络,均衡话务量,在有限带宽内提高系统容量;最大程度减少干扰,达到所要求的Qo S;在保证话音业务的同时,满足高速数据业务的需求;优化无线参数;在满足覆盖、容量和服务质量前提下,尽量减少系统设备单元,降低成本。
China’s three major telecommunications operators have fully entered the 4G era, first-tier cities have completed coverage, second and third tier cities are in full swing in the construction. This article on the three major carriers have TD-LTE standard wireless network in the early days of how to plan a basic introduction. Wireless network planning mainly refers to the link budget, capacity estimation, given base station size and base station configuration to meet the coverage, capacity network performance indicators. Network planning must achieve the maximum seamless coverage in the service area; scientifically predict the traffic distribution, reasonably layout the network, balance the traffic volume, increase the system capacity within the limited bandwidth, minimize the interference and achieve the required Qo S; To ensure voice services at the same time, to meet the needs of high-speed data services; optimize wireless parameters; to meet the coverage, capacity and quality of services under the premise of minimizing the system equipment unit and reduce costs.
