Aiming at the problem of many repeated traffic in the network, the idea of offset-caching (OC) was put forward creatively based on the idea of large-scale access convergence network. In the backbone network, the hot content was pushed to the network access point as close as possible to the users. In the access network, the cached content in the network was multicasted access point to the users. The idea would provide a resolution to improve the quality of the user experience, reduce the network traffic and the server load.

GPS is used for localization usually, but cannot be applied indoors. It was a popular topic on how to do the indoor localization accurately. In the early research, indoor localization system based on Wi-Fi fingerprints suffer from the accuracy and site survey problems. Therefore, a novel room-level indoor localization system was designed, which solved the localization problem by using multi-information fusion. Firstly, a top-n candidate through the Wi-Fi fingerprint was gotten, kNN classification algorithm was used after MAC address and the RSSI were gotten. The candidate set was filtered by the geomagnetic signal and the image information. Finally, the social information was used to give the final location results of people in the room. The system was validated on smart phone with Android system. The experimental results show that proposed method is more accurate than the Wi-Fi fingerprint localization algorithm.

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.
