The Application of the Narrowband-IoT in the Smoke Alarm

摘要

Narrowband Internet of Things (NB-IoT) is a new radio access technology, in 3GPP, NB-IoT has been introduced to support the Internet of Things. This paper summarizes the application of NB-IoT in the wireless sensor network, and describes how NB-IoT can solve the problem of Internet of things, including deployment, battery life, equipment complexity and other common problems. Considering that stand-alone as a dedicated carrier can cover wider range, does not conflict with the existing system, and has low power consumption, it's very suitable for smoke alarm which care more about wide coverage, low power requirements. This article presents a detailed model that describes how to use NB-IoT can make smoke alarm working in the power saving mode (PSM) and how to setup parameters in this mode. This paper also shared some requirements of GA1151-2014 General requirements for wireless communication function of fire alarm system, and pointed out the requirement of smoke alarm to NB-IoT.
