摘要
据统计,到2025年,全球物联网的终端连接将达到50亿以上,这显然是一个颠覆性的机会。在此背景下,满足物联网广覆盖、大容量、低功耗和低成本等特定需求的新型LPWA低功耗广域覆盖通信技术应运而生,包括两种基于LTE的移动通信新技术:Cat-NB1和Cat-M1。对上述两种技术的演进和关键技术进行了分析和比较,并深入研究了两者用到的核心低功耗技术和应用,最后分析了基于LTE的移动物联网通信新技术的实现策略,并对其应用和发展进行了展望。
According to statistics,the terminal connection of global Internet of things will reach more than 5 billion by 2025,this is a momentous opportunity.In this context,a new LPWA low-power consumption and wide-area coverage communication technology emerges,which can meet the special requirements of Io T such as wide-area coverage,large capacity,low power consumption,low cost,etc.The two most important technologies are LTE-based mobile communication technologies,namely Cat-NB1 and Cat-M1.The evolution and key technologies of the two technologies are analyzed and compared,and the core low-power consumption technology and application are studied.Finally,the realization strategy of the new mobile communication technology based on LTE is analyzed,and its application and development are looked forward.
