基于eMTC的物联网规划优化关键技术研究
|
摘要
eMTC是基于3GPP LTE标准协议演进的蜂窝物联网技术,主要面向中低速率、深度覆盖、低功耗、大连接的物联网应用场景。首先从eMTC网络架构、eMTC关键技术特性、eMTC与LTE共存等多个角度进行理论分析和研究。其次,结合国内首个大规模eMTC试商用网络——厦门eMTC试验网开展技术评估和测评分析,归纳和总结出网络部署相关建议,为全国商用规模部署eMTC网络提供有效的技术支撑和借鉴。
eMTC is a cellular IoT technology based on the evolution of 3 GPP LTE standard protocol. It is mainly targeted at the IoT application scenarios of medium and low speed,deep coverage,low power consumption and large connection. Firstly,theoretical analysis and research on eMTC network architecture,key technical characteristics of eMTC,coexistence of eMTC and LTE are carried out. Secondly,combined with the first domestic large-scale eMTC trial commercial networks——Xiamen eMTC trial network,technical evaluation and evaluation analysis are carried out,and the relevant suggestions on network deployment are summarized and concluded to provide effective technical support and reference for the nationwide commercial deployment of eMTC network.
