… Abstract: We show the first-ever live demonstration of a robust mobile free space optical
system using three-stage high-speed beam tracking technology including 2-dimensional
photodetector array based spatial diversity combining, which enables the mobility support in
6G. � 2024 The Author(s) … However, the field of view (FoV) still has some rooms for
improvement because the residual misalignment impacts such a system and limits the
mobility support as well. In this demonstration, we combine [3] with [4] and introduce the�…
