The Internet of Things (IoT) is a rapidly growing field that requires location information for many use cases. The 3rd Generation Partnership Project (3GPP) has recognized the importance of positioning in IoT and has made significant efforts to enhance positioning support in its IoT technologies during Release 14. This article, titled "Positioning for the Internet of Things: A 3GPP Perspective," provides an overview of the design challenges faced in Long-Term Evolution Machine Type Communication (LTE-M) and Narrowband IoT (NB-IoT) regarding positioning support. The authors highlight the work done by 3GPP to improve the positioning support for LTE-M and NB-IoT. They specifically focus on Observed Time Difference of Arrival (OTDOA), which is a downlink based positioning method. The article discusses the architecture and protocols involved in OTDOA, as well as the designs of OTDOA positioning reference signals. To illustrate the effectiveness of OTDOA, simulation results are presented to showcase its positioning performance. The authors emphasize that enhancing positioning support is crucial for improving the overall ecosystem of 3GPP-based IoT technologies. Overall, this article provides valuable insights into the design challenges and advancements in positioning support for LTE-M and NB-IoT from a 3GPP perspective. It serves as a comprehensive resource for researchers and professionals working on IoT technologies and highlights the significance of location information in various IoT applications.
