This work describes a beam-steered infrared light communication (BS-ILC) system that facilitates non-shared and ultra-high data rate communications to individual user devices. The BS-ILC system comprises optical antennas, vision-based user localizati

By means of narrow infrared beams very high capacity wireless links can be set up to users individually, while also offering high privacy and high energy efficiency. Accurate device localization for steering the beams is required. This has been achie

We expanded our concept of N×N matrix of photodiodes, scalable to large aperture and wide field-of-view while retaining high bandwidth. A simple GbE OWC receiver with 4×4 matrix and single TIA was realised and showed a FoV>10 deg. We demonstrated G

Using a low-cost optical camera, we demonstrated an accurate and fast localization technique for ultra-high capacity beam-steered optical wireless communication. Multiple user devices have been localized simultaneously within 25ms for less than 5mm a

The free-space narrow infrared beams can offer unprecedented data capacity to devices individually, as they can provide non-shared connections that have a large link power budget. By means of a fully passive module based on a high port count arrayed
