“…Most of the existing VLC channel models are mainly based on the infrared channel models. As reported in [26], [37]- [40], valuable research has been dedicated to modelling the VLC channel by considering some of the practical VLC channel characteristics. In particular, multipath propagation imposed by reflections results in spreading of the received signal, and the power delay profile (PDP) can be used to analyze the effect of multipath dispersion between transceivers.…”

Abstract-In order to counteract the explosive escalation of wireless tele-traffic, the communication spectrum has been gradually expanded from the conventional radio frequency (RF) band to the optical wireless (OW) domain. By integrating the classic RF band relying on diverse radio techniques and optical bands, the next-generation heterogeneous networks (HetNets) are expected to offer a potential solution for supporting the ever-increasing wireless tele-traffic. Owing to its abundant unlicensed spectral resources, visible light communications (VLC) combined with advanced illumination constitute a competent candidate for complementing the existing RF networks. Although the advantages of VLC are multi-fold, some challenges arise when incorporating VLC into the classic RF HetNet environments, which may require new system architectures. The user-centric (UC) design principle for VLC environments constitutes a novel and competitive design paradigm for the super dense multi-tier cell combinations of HetNets. The UC concept may be expected to become one of the disruptive techniques to be used in the forthcoming fifthgeneration era. This paper provides a comprehensive survey of visible-light-aided OW systems with special emphasis on the design and optimization of VLC networks, where the radically new UC design philosophy is reviewed. Finally, design guidelines are provided for VLC systems.

“…Comparing the interference level that affected by environmental of visible light communication (VLC) and infrared communication, VLC is comparatively more stable than infrared communication [1] and enables to enhance data transmission speed to Mbit/s [2][3][4][5][6]. VLC possesses the advantages of lighting and data transmission, therefore, it has a high safety since light is straight forward and unable to pass through buildings directly to transfer data [7].…”

This work developed a multi-function electronic label of product for hypermarket which mainly aims at improving the product information and safety for both consumers and hypermarket. This device applies the techniques of visible light communication (VLC) and adopts existing LED lights from hypermarket to manage uniformly all contents of product labels and provide emergency light. Master control system on hypermarket server can control LED lights to transmit signals to the electronic label. At the same time, when electronic label on product shelves from supermarket receives the signals, the label displays the product information such asprice, calories and so on. The emergency lights on the both sides of the label display board will illuminate during the blackout and lead consumers to escape from the hypermarket safely.

This article reviews the visible light communications (VLC), a technology in which the visible spectrum is modulated to transmit data. It presents the VLC communication system: the transmitter, the channel, and the receiver. The single and multichannel transceivers are presented. The channel for a system that uses a single light‐emitting diodes (LED) and the matrix representing the multicolor channel are discussed. Various modulation schemes, basic techniques used to implement a VLC system, and different causes of dimming are discussed. In addition, standardization of the VLC technology, applications, as well as challenges for VLC practical implementation and commercialization are reviewed.
