This paper discusses the opportunities for visible light communications (VLC) in the future 6G. VLC is a highly attractive optical communication approach for short-range communications, which complements radio. The use of reconfigurable optical-radio networks creates a high performance, highly flexible communication system that can be used in the most stringent environments of 6G. The paper presents and discusses other novel VLC concepts, such as interactive VLC, light-based IoT, living surfaces and optical communications through bio-tissues. These very promising concepts can be used in the identified 6G verticals, opening new areas of research for 6G.

“…These unique perspectives, together with an inherent ability to provide small size isolated cells, allow the VLC technology to be considered a major candidate in Fifth Generation (5G) and Sixth Generation (6G) mobile and wireless networks [ 12 , 13 , 14 ]. It should be also mentioned that in addition to lighting and communication functions, the VLC technology has the potential to provide high accuracy indoor localization and positioning that reaches centimeter precisions [ 15 , 16 ], opening the door to a whole new range of applications [ 17 ], which in turn increases the need for a better mobility [ 18 , 19 ] and multi-user connections [ 20 ].…”

The use of visible light communications technology in communication-based vehicle applications is gaining more and more interest as the research community is constantly overcoming challenge after challenge. In this context, this article addresses the issues associated with the use of Visible Light Communications (VLC) technology in Vehicle-to-Vehicle (V2V) communications, while focusing on two crucial issues. On the one hand, it aims to investigate the achievable communication distance in V2V applications while addressing the least favorable case, namely the one when a standard vehicle rear lighting system is used as a VLC emitter. On the other hand, this article investigates another highly unfavorable use case scenario, i.e., the case when two vehicles are located on adjacent lanes, rather than on the same lane. In order to evaluate the compatibility of the VLC technology with the usage in inter-vehicle communication, a VLC prototype is intensively evaluated in outdoor conditions. The experimental results show a record V2V VLC distance of 75 m, while providing a Bit Error Ratio (BER) of 10−7–10−6. The results also show that the VLC technology is able to provide V2V connectivity even in a situation where the vehicles are located on adjacent lanes, without a major impact on the link performances. Nevertheless, this situation generates an initial no-coverage zone, which is determined by the VLC receiver reception angle, whereas in some cases, vehicle misalignment can generate a BER increase that can go up to two orders of magnitude.

“…It has been proposed for many different scenarios, both indoors and outdoors [ 4 ]. For indoor applications, there exists a wide variety of applications, such as extending the capacity and complementing the radio frequency (RF) systems [ 5 ], positioning and resource monitoring [ 6 , 7 ], intruder detection [ 8 ] or providing coverage where RF transmission is not allowed [ 9 ], among others. Outdoor VLC applications comprise vehicle-to-vehicle communications [ 10 , 11 , 12 ] or some trials and analysis for long distance transmission [ 13 , 14 , 15 ].…”

Visible light communications (VLC) have received significant attention as a way of moving part of the saturated indoor wireless traffic to the wide and unregulated visible optical spectrum. Nowadays, VLC are considered as a suitable technology, for several applications such as high-rate data transmission, supporting internet of things communications or positioning. The signal processing originally derived from radio-frequency (RF) systems such as cooperative or precoding schemes can be applied to VLC. However, its implementation is not straightforward. Furthermore, unlike RF transmission, VLC present a predominant line-of-sight link, although a weak non-LoS component may appear due to the reflection of the light on walls, floor, ceiling and nearby objects. Blocking effects may compromise the performance of the aforementioned transmission schemes. There exist several surveys in the literature focused on VLC and its applications, but the management of the shadowing and interference in VLC requires a comprehensive study. To fill this gap, this work introduces the implementation of cooperative and precoding schemes to VLC, while remarking their benefits and drawbacks for overcoming the shadowing effects. After that, the combination of both cooperative and precoding schemes is analyzed as a way of providing resilient VLC networks. Finally, we propose several open issues that the cooperative and precoding schemes must face in order to provide satisfactory VLC performance in indoor scenarios.
