5G and 6G mobile communication systems will encompass a Non-Terrestrial Network (NTN) that will include different satellite systems (LEO including cubesats/MEO/GEO) as well as High-Altitude Platform Stations (HAPS) in the stratosphere and Unmanned Aerial Vehicles (UAV) to cover remote areas that otherwise could not have access to the Internet. IoT via NTN is very important for a wide range of applications such as Earth monitoring, smart agriculture, pollution control, sea monitoring, and disaster management. In a first part, this seminar will investigate various architectural and networking options for collecting IoT data via satellite. Moreover, a second part of the seminar will address and compare two important technologies NB-IoT (part of 5G NTN specification according to 3GPP Release 17) and LoRa/LoRaWAN (including the LR-FHSS alternative for satellite systems). Finally, a review of current satellite IoT systems supporting NB-IoT or LoRa/LR-FHSS will be provided. Speaker(s): Giovanni Giambene, Virtual: https://events.vtools.ieee.org/m/388859
