Recently, Narrowband IoT (NB-IoT) and Long Term Evolution Machine Type Communications Category M1 (Cat-M1) have been proposed as promising Low-Power Wide-Area Network (LPWAN) technologies for Internet-of-Things (IoT) applications. An IoT device equipped with a NB-IoT/Cat-M1 communication module can transmit data to a host on the Internet. However, at present, a host on the Internet cannot use real-life network applications to remotely log into a NB-IoT/Cat-M1 device to manage it. In this work, we design and implement the first system in the world by which the IoT device manager can use real-life network applications such as ssh to remotely log into and then manage NB-IoT/Cat-M1 devices. We use this system to measure the performances of the used NB-IoT/Cat-M1 network and report several important findings in this paper.
