When the base station goes to space: how NTN is changing internet access architecture

This article explores the rapid development of Non-Terrestrial Networks (NTN) and its impact on mobile network architecture. The author examines how the integration of satellite communications into smartphones is reshaping traditional internet access. The focus is on projects by SpaceX (Starlink Mobile) and Bureau 1440, as well as the adoption of NR-NTN standards by chip manufacturers. The core question is how moving the first network node from the ground to orbit transforms radio access architecture, Packet Core operations, and traffic control mechanisms. The author discusses the technical aspects of satellite transport and real-world deployment scenarios, emphasizing that the technology is moving from experimental development to practical implementation. This fundamentally alters the structure of mobile communications by shifting critical data control points into space.
