蜂窝物联网技术NB-IoT与eMTC的对比研究

Comparative Study of Cellular Internet of Things Technology NB-IoT and eMTC

随着信息技术的不断发展,3GPP制定了低功耗低成本的蜂窝物联网技术NB-IoT与eMTC技术,是目前全球运营商主推方向,这两种技术之间既存在共性又各自有其优点。本文详细介绍了NB-IoT与eMTC技术的各项参数,并通过多方面对比,分析了两种技术各自对应的应用场景,找出其互补关系和共同发展的方向。据此,下文主要就NB-IoT与eMTC技术进行对比研究,希望可以为该方面的研究提供参考与建议,有助于促进蜂窝物联网产品的快速成熟,推动中国物联网的发展。

With the continuous development of information technology,3 GPP has developed low-power and low-cost cellular internet of things technology NB-IoT and eMTC technology,which are the main direction of global operators at present. There are both similarities and advantages between the two technologies. In this paper,the parameters of NB-IoT and eMTC technology are introduced in detail,and the corresponding application scenarios of each technology are analyzed through multi-aspect comparison,so as to find out the complementary relationship and common development direction. Accordingly,the following is a comparative study of NB-IoT and eMTC technology,hoping to provide reference and suggestions for the research in this area,which will help promote the rapid maturity of cellular internet of things products and promote the development of China’s internet of things.
