“…Some of the prospective applications of VLC are given below: ITS: The lightning infrastructure is beginning to adopt LEDs for building lights, street lamps, and automotive lights. VLC is now considered for communication between vehicle‐to‐vehicle [173] and vehicle‐to‐central office [174]. To make VLC viable for ITS applications [33] in outdoor environments, some other factors such as ambient light, fog, rain, and smoke have to be considered. Underwater communications: VLC has a strong capability for underwater communication, especially for high‐speed aquatic communications, underwater vehicle to vehicle, and vehicle to driver communication [90].…”

Visible light communication (VLC) is a promising candidate for future indoor wireless communication. Light emitting diodes (LEDs) are popular choices as transmitters for VLC, since they are energy efficient and have the ability to provide illumination and data transmission simultaneously. VLC is attractive for reasons such as security, the ability to use a licence free spectrum, and broad bandwidth. Previous review articles on VLC mainly focused on VLC network algorithms, implementation challenges, system design, applications, and physical layer technologies. Unlike the existing reviews, this study presents stateof-the-art VLC systems for high-speed data communication in the gigabit range and the techniques to achieve such high data rates. In addition, concepts such as LED modelling and fabrication process, recent commercial advancements of VLC products, and hybrid/heterogeneous networks to achieve high data rate are highlighted in this study. For this purpose, some key technologies of VLC systems, including channel equalisation from both transmitter and receiver sides, higher-order modulation techniques, wavelength division multiplexing, multiple input multiple output technology, LED modelling, and advanced fabrication processes are discussed. This study also covers recent advancements in commercialisation of VLC technology, and recent progress made by various research groups.

“…This makes it feasible to make use of the lighting infrastructure for signalling, communication, and positioning, leading to the concept of an ITS. VLC is now considered for communication within a vehicle [302], between vehicles (i.e. vehicle-to-vehicle (V2V) communication) [303][304][305][306][307][308] and vehicle-to-Infrastructure (V2I) [309][310][311].…”

The field of visible light communications (VLC) has gained significant interest over the last decade, in both fibre and free-space embodiments. In fibre systems, the availability of low cost polymer optical fibre (POF) that is compatible with visible data communications has been a key enabler. In free-space applications, the availability of hundreds of THz of the unregulated spectrum makes VLC attractive for wireless communications. This paper provides an overview of the recent developments in VLC systems based on gallium nitride (GaN) light-emitting diodes (LEDs), covering aspects from sources to systems. The state-of-the-art technology enabling bandwidth of GaN LEDs in the range of >400 MHz is explored. Furthermore, advances in key technologies, including advanced modulation, equalisation, and multiplexing that have enabled free-space VLC data rates beyond 10 Gb s −1 are also outlined.

Light Fidelity (Li-Fi) is a wireless technology that utilizes light emitting diodes to convey data. Li-Fi has emerged as a promising alternative to radio frequency communication technology in recent years. This paper examines the performance characterisation between NRZ-OOK and carrier-less amplitude-phase modulation (CAP-2, CAP-4 and CAP-8), within a simulated Li-Fi environment. For the parameters of interest, the eye pattern, bit error rate (BER) and constellation diagram are reported. As no distance is specified in the simulation, the BER for CAP is zero, allowing an ideal transmission to be emulated. The scatter diagram increases as the number of CAP modulations increases. For the eye pattern, CAP modulation provides a better visual representation of how noise might affect system performance compared to OOK modulation.
