“Massive Internet of Things: Opportunities and Challenges”
- Massive Internet of Things (mIoT) is deemed to connect billions of miscellaneous mobile devices or IoT devices that empowers individuals and industries to achieve their full potential. A plethora of new applications, such as autonomous driving, remote health care, smart-homes, smart-grids etc., are being innovated via mIoT, in which ubiquitous connectivity among massive IoT devices are fully automated without human intervention. The successful operation of these IoT applications faces various challenges, among them providing wireless access for the tremendous number of IoT devices has been considered to be the main problem. Different connectivity technologies such as cellular based NB-IoT, LTE-M, EC-GSM-IoT and unlicensed spectrum technologies such as LoRa and Sigfox are emerging as cheaper connectivity options optimized for range and energy. Cellular-based network is deemed as a potential solution to provide last mile connectivity for massive number of IoT devices, due to its advantages in high scalability, diversity, and security, as well as low cost of additional infrastructure deployments. However, in certain scenarios, where the cellular infrastructure is infeasible, unlicensed spectrum based technologies are to be employed. In this talk, Professor Nallanathan will provide the details of licensed and unlicensed bands connectivity technologies with applications. He will also discuss the technical challenges in mIoT.
