[Abstract] Narrowband Internet of things (NB-IoT) effectively improves the competition capacity when using the traditional cellular network to carry the service of IoT. NB-IoT network can be deployed independently, or upgraded through the existing long term evolution (LTE) network. Operators can quickly build up a continuous depth coverage, low cost, low power consumption, roaming, quality guaranteed narrowband dedicated networking to develop new services. Currently, NB-IoT are facing many challenges, such as new business model, the maturity of industrial chain, the competition from other technologies and so on.
