Evaluating NB-IoT Technology for Industrial Communication
The Internet of Things (IoT) ecosystem generally heavily depends on a strong connectivity to transform and support a range of IoT applications across industries like manufacturing, transportation, utilities and healthcare. In industrial automation, especially for factory and process automation, IoT connectivity is required to support massive Machine Type Communications (mMTC) use cases which address deep coverage, low cost, low power and high density IoT nodes as well as Ultra-Reliable and Low Latency Communication (URLLC) use cases which have ultra-low latency and high reliability requirements. Thus, technologies that provide low power wide area (LPWA) connectivity have gained much popularity in recent years to meet the requirements of these use cases. LPWA technologies such as SigFox, Ingenu, LoRA, Weightless, most of which are prioprietary, are available but have the limitation that they operate in unlicensed spectrum and are not able to guarantee the required quality of service (QoS). Meanwhile the Narrowband IoT (NB-IoT) LPWA cellular technology standardized by the Third Generation Partnership Project (3GPP) in Release 13 uses licensed spectrum and optimized for mMTC use cases. Currently, this technology does not fully support URLLC use cases. In this paper, we analyze and evaluate the techniques and enabling technologies that would enable NB-IoT to support such use cases that require very high reliability and very low end-to-end delay in the order of few milliseconds.
