| 摘 要： | 在800MHz频段现有CDMA网络共站升级2.1GHz频段LTE FDD网络。以密集市区站间距500m场景为例,首先分析2.1GHz频段天线下倾角对LTE FDD网络覆盖性能和容量性能的影响,给出相应的最优天线下倾角配置原则;然后通过与800MHz频段网络最优天线下倾角进行比较,给出跨频共站升级方案天线下倾角的优化策略。跨频共站升级LTE FDD网络方案天线下倾角优化策略的研究,可为4G网络的升级与部署提供可靠的参考数据。

| Abstract: | The existing CDMA network on 800MHz upgrades to LTE FDD network on 2.1GHz on the same site. Take the dense urban ISD（lnter Site Distance） 500m as an example, firstly, the effect of antenna down-tilt on 2.1GHz on network coverage and capacity performance of LTE FDD is analyzed. The corresponding optimal principles of antenna down-tilt configuration are given. Then compared with the optimal antenna down-tilt on 800MHz, the optimization strategy of the antenna down-tilt in cross-frequency upgrade scheme is proposed. The study of the antenna down-tilt optimization strategy about the upgrade to LTE FDD cross-t？equency on the same site can provide detailed and reliable reference data for 4G network upgrade and deployment. |
