Analyzing the maximum angle of light‐emitting diodes for indoor visible light communication

Electronics Letters, Volume 59, Issue 18, September 2023., 2023
An optimal arrangement of the Light‐Emitting Diodes for an indoor Visible Light Communication setup is presented by using the simulation model. The validation simulation results for a Line‐of‐Sight configuration that show the movement of the angle change can be carried out easily.

Improved LED arrangement through outage probability minimization in LiFi communication systems

IET Communications, Volume 17, Issue 8, Page 987-998, May 2023., 2023
We propose an improved method to arrange the light emitting diodes (LED) on the ceiling for an indoor visible light communication (VLC) system. A LiFi‐based connection is considered where several LEDs are placed on the ceiling of an office and communicate with several receiver (user) located randomly within the room area. We propose to find the optimal

A Real‐Time Baseband Processor for Li‐Fi Internet Access

Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022
In the past years, light fidelity (Li‐Fi) has been gaining popularity in the research. However, many researches have done only offline transmission with laboratory instruments. As a result, it is not practical to be used in commercial product, due to its cost and size.

Artificial Phototropic Systems for Enhanced Light Harvesting Based on a Liquid Crystal Elastomer

Advanced Intelligent Systems, Volume 3, Issue 10, October 2021., 2021
A versatile, low‐cost, mechanically strong, unconcentrated sunlight‐driven artificial phototropic system is reported. Benefited from double‐leg and bimorph design, it can bear load and achieve large reorientation angle simultaneously. This system is demonstrated to be able to recover the oblique‐incidence‐induced energy‐density loss for photovoltaics ...
