LTE FDD与NB-IoT融合组网建设方案

LTE FDD and NB-IoT fusion network engineering construction scheme

中国移动现已建成TD-LTE精品网络,随着移动通信的快速发展,现阶段考虑引入LTE FDD和NB-IoT网络。LTE FDD能广覆盖和深度覆盖,提升用户感知,NB-IoT是一种基于蜂窝物联网络的新兴技术,应用广泛。本文通过对LTEFDD和NB-IoT的技术特点进行简要分析,结合现网实际情况给出频率规划和建设方案,为未来NB-IoT和LTE FDD的统一部署提供技术参考。

China Mobile builds a TD-LTE quality network now, with the rapid development of mobile communications, consider introducing LTE FDD and NB-IoT networks at this stage. LTE FDD can enhance wide coverage and deep coverage, and improve user’s perception, NB-IoT is an emerging technology based on cellular internet of things which are widely used. The paper briefl y analyzes the technical characteristics of LTE FDD and NB-IoT, the frequency planning and construction schemes are given based on the actual situation of the current network, providing a technical reference for the unifi ed deployment of NB-IoT and LTE FDD in the future.
