Abstract
During the last few years, the interest around Machine-Type Communications (MTC) and Internet of Things (IoT) is growing exponentially. The Third Generation Partnership Project (3GPP), acknowledging the importance of this trend, has introduced a number of key features to support IoT. Specifically they provided progressively improved support for Low Power Wide Area Network (LPWAN) introducing the so called Narrowband IoT (NB-IoT) in 2017 for better serving IoT use cases. Furthermore, the integration of Non Terrestrial Networks (NTN) in the New Radio (NR) is playing an important role, enabling many different use cases for the forthcoming 5G system. This work aims at analyzing the feasibility of integrating NB- IoT with satellite communication systems; the main issues are investigated with a particular focus on the impact of doppler shift on NB-IoT waveform. Possible solutions are proposed, empowering the utilization of the NB-IoT terrestrial standard within satellite channel.
