Free Space Optical Communication: An Enabling Backhaul Technology for 6G Non-Terrestrial Networks
The deployment of non-terrestrial networks (NTNs) is envisioned to achieve global coverage for 6G and beyond.In addition to space nodes, aerial NTN nodes such as high-altitude platform stations (HAPSs) and rotary-wing unmanned aerial vehicles (UAVs) could be deployed, based on the intended coverage and operational altitude requirements.NTN nodes ha
