Bio: FELIPE AUGUSTO TONDO received the D.Sc. degrees in Electrical Engineering from the Federal University of Santa Catarina (UFSC), Brazil, in 2024. His M.Sc. degree in Electrical Engineering from the Federal University of Rio Grande do Sul, Brazil, in 2017. Prior to that, he completed his B.Sc. degree in Electrical Engineering from the University of Caxias do Sul (UCS), Brazil, in 2014. From 2015 to 2022, he held a position as a Professor in the Department of Electrical, Electronic, and Control and Automation Engineering of UCS. His research is focused on wireless communications, specifically with ground-to-satellite networks. He has worked in the efficient resource allocation for IoT networks via Low Orbit Satellites (LEOs). In 2022 he collaborated with Programa Institucional de Fomento a la Investigación, Desarrollo e Innovación, Universidad Tecnológica Metropolitana (UTEM), Santiago, Chile. In 2023, your research project was accepted by the Brazilian National Program for Scientific and Technological Development, leading to an exchange opportunity at the Centre for Wireless Communications (CWC) in Oulu, Finland. He is currently a postdoctoral researcher in the Department of Electrical and Electronics Engineering at UFSC and also collaborates with the Brazilian 6G program.

Abstract: The satellite-based Internet of Things (IoT) networks are emerging as a key technology to provide global connectivity for massive numbers of devices. However, supporting scalable uplink transmissions from thousands of low-power devices remains a significant challenge. In this talk, we discuss new uplink access strategies for Direct-to-Satellite (DtS) IoT networks. We also outline the main concepts behind the proposed approaches, analyzing their performance compared to traditional random access schemes. The presentation will also include a brief overview of the simulation tools and framework used to evaluate these strategies, including a simulation environment that incorporates realistic satellite trajectory information. Simulation results show significant improvements in scalability and goodput, highlighting the potential of the proposed solutions for future satellite IoT systems. The presentation concludes with future research directions and key open aspects currently under final investigation.
