Stochastic Analysis of THz Band Satellite Channels' Quality

The satellite networks are among the most promising platform to achieve true global connectivity. The millimeter wave and THz frequencies on the other hand provide large data rates needed particularly in backhaul and fronthaul networks. This paper looks into the stochastic performance of +100 GHz channels in satellite uplink and downlink cases. It is shown that while SNRs can be quite good, there are still great challenges to go around very large losses and the large outage probabilities that those cause. This is particularly the case when we add on the channel losses possible rain and cloud losses, antenna misalignment losses, or any other losses that can occur in the satellite channels.
