摘要

Between a novel optical hotspot with +/- 30 degrees FoV and 6 nomadic user terminals using mirror-based steering with +/- 50 degrees FoV, we demonstrate point-to-multipoint bi-directional indoor optical wireless transmissions over 4 metres with flexible bandwidth resource allocation using WDM-OFDMA. Single-wavelength channel data capacity is 28 Gb/s. (C) 2022 The Author(s)
