This paper aims at revealing the main technical issues that have not been fully addressed by the existing LEO-SAN designs, from three aspects namely random access, beam management and Doppler-resistant transmission technologies. Promising technologies to address these challenges are also discussed, respectively. Finally, the future research directions are envisioned.
While satellites have been connecting people to the internet or making their way home, growth in launches raises legal issues moving forward
The FCC has proposed a series of changes in the low-earth orbit (LEO) satellite systems rules, including a new spectrum sharing regulation
