The Narrow Band Internet of Things (NB-IoT) for low-power, wide-coverage, and low-cost requirements solves the problem of massive Internet of Things device connectivity. NB-IoT supports device connection with large data throughput and long standby time. It is unmatched by traditional cellular data network technology and Bluetooth technology. By combining the NB-IoT positioning with the Lagrangian multiplier improved constrained least squares localization algorithm and the GSM mobile terminal delay estimation algorithm in NLOS environment, a feasible indoor three-dimensional positioning method is proposed. In addition, it reduces the influence of environmental factors on positioning and improves the accuracy of indoor three-dimensional positioning.
