Abstract: The main challenges faced by low power enabled IoT services come from two aspects. From the network and terminal aspect, module cost is high, and power consumption, as well as network coverage is not ideal. From the operation aspect, connectivity increases but income does not increase in the same scale as the connectivity does. Additionally, business fragmentation is another challenge from operation aspect. Comparing with other un-authorized spectrum LPWANs, e.g., LoRa, NB-IoT has many advantages in terms of mobility, reliability and security, and so on. So it is more suitable for large scale operation. In the end, the NB-IoT operation strategies are proposed, including quickly deploying NB-IoT network, expanding the network connection services to upper services, focusing on key industries and strengthening industrial cooperation.
