TL;DR: In this article, a 2D beam-steered optical wireless communication system with a matrix of miniature corner-cube retro-reflectors has been demonstrated in an indoor laboratory system setup.
Abstract: 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 achieved within the 10 cm pico-cell resolution of a 2D beam-steered optical wireless communication system by applying a matrix of miniature corner-cube retro-reflectors. The localization process is self-calibrating, and does not need power-consuming elements at the receiver. In an indoor laboratory system setup, real-time transfer of multiple 10GbE high-definition video streams has been demonstrated.

TL;DR: In this article, a low-complexity broadband optical wireless receiver based on a novel 2-dimensional matrix of photodiodes yielding a large aperture and wide FoV in an IR beam-steered system was proposed.
Abstract: We propose and analyse a low-complexity broadband optical wireless receiver based on a novel 2-dimensional matrix of photodiodes yielding a large aperture and wide FoV in an IR beam-steered system. Experimentally more than 1Gbit/s OOK transmission is shown with 10cm IR beams at a $FoV=10^{c}$ .
