Seminar im Wintersemester 2024
Satellite communication has been around for some time, mainly via geostationary Earth orbit (GEO) satellites. The GEO is at an altitude of 35786 km above Earth’s equator. This leads to very high propagation delays, resulting in typical round trip times of ~600 ms. Such high latencies are problematic for some applications and transport layer protocols like TCP and QUIC.
Recently, the deployment of low Earth orbit (LEO) megaconstellations (e.g., Starlink) has caused a lot of attention, providing high data rates and low latencies.
In this seminar, both state-of-the-art and future satellite communication systems will be presented and discussed.
Preliminary list of topics:
- Application and protocol performance of GEO and LEO satellite communication
- Simulation models for LEO megaconstellations
- Satellite communication for 5G and beyond: Non-Terrestrial Networks
- Direct-to-cell and IoT satellite communication
