Abstract

Visible light communication (VLC) is an emerging field in optical wireless communications, where white light-emitting diodes (LEDs) can be simultaneously used for illumination and data communications. Since 2011, VLC technology has gained momentum supported by the release of the IEEE 802.15.7 draft standard. This defines the physical and medium access control (MAC) layers supporting multiple topologies with data rates up to 96 Mb/s, for indoor and outdoor applications [1]. Also, several live demonstrations of VLC technology and its potential applications have contributed to increase its popularity among the general public [26]. It is expected that the popularity of VLC will continue to grow in the future and new applications and services will emerge to help mature this technology. According to [7], the global market for VLC is expected to grow at a compound annual growth rate of 109.2% from 2015 to 2022. This chapter outlines detailed information for VLC system architects who wish to prototype high data-rate systems in real hardware. Section 14.1.1 provides general information about the most popular envisioned applications for both low and high data-rate VLC systems. Section 14.1.2 takes a closer look at high-speed VLC demonstrators, and Section 14.1.3 discusses VLC implementation technologies.
