About this Research Topic
Visible light communication (VLC) has gained enormous popularity across numerous domains including; short- and long-range communications, positioning and intelligent transport systems, among others. In general, it has been positioned as an emerging access network technology that has become an ever-increasing topic of interest over the last two decades. VLC often makes use of solid-state lighting-emitting diode (LED) infrastructure to provide simultaneous room illumination and data communication functionality. Data is communicated via intensity modulation and direct detection of visible wavelengths and offers 3-400 THz of unlicensed, unregulated bandwidth, making it an extremely attractive solution to the upcoming capacity crunch and for 5G and beyond access technologies.
Several key research challenges have emerged within the VLC domain, including multi-technology network tenancy, high data rates, physical layer security, resource allocation, co-design of high-speed data rates and dimming capabilities, amongst others. VLC technology is of interest to the wider communications systems community due to its flexibility of deployment and capability to provide low-cost infrastructure that will easily integrate into a multi-technology network ecosystem, enabling new internet services and high-speed connectivity. It is envisaged that VLC will not replace radio frequency (RF) technologies, but complement them, adding inherent functionalities such as high bandwidth, low latency connectivity for media/gaming applications in homes, or individual attocell connectivity with a high level of security in indoor environments. In terms of global development, the standards have been developed that define the minimum operation of VLC networks in IEEE802.15.7 as well as the recently formed IEEE802.11bb VLC standard.
The field of VLC, therefore, promises substantial opportunities for basic and applied research and development. The proposed research topic will provide an opportunity for a thorough assessment of the current state of VLC across numerous applications, helping to develop the state-of-the-art.
