基于蜂窝网络的物联网关键技术及业务应用

摘要

介绍了物联网业务发展的趋势，分析了基于蜂窝网络的物联网应用需求及发展前景，根据蜂窝网络承载的物联网业务特征及业务发展需求，按照窄带通信系统、宽带通信系统（3G/4G通信系统）2种技术发展趋势，总结3GPP在2种技术解决方案中的关键技术研究和标准化工作进展。为适应物联网业务发展需求，需要研究并确定部署频段、关键技术演进、发展路标等蜂窝网络演进和部署策略。为了应对激烈的市场竞争，需要加快物联网技术研究和商用部署。%It describes the trend of Internet of Things,analyzes application demand and development prospect of Internet of Things based on cel ular network. According to the service features and market developing requirements,3GPP devotes lots of efforts to the key technologies research and standardization work on both several candidate narrow-band Internet of Things solutions and new features of 3G and 4G technologies. The further researches of the operator side should focus on the network evolution and deployment strategies,including spectrum,key technologies,roadmaps,and other critical issues. Confronted with the furious competition of the market,operators also need to accelerate the research progress and commercial deployment of In-ternet of Things.
