由于在过去二十年中移动的通信的大幅增长，蜂窝系统已经求助于带宽的更充分和更密集的重用来科普增长的需求。一方面，这种方法提高了可实现的系统容量。然而，另一方面，密集的空间重用所造成的干扰增加固有地限制了可实现的网络吞吐量。因此，用户需求和网络能力之间的频谱效率差距不断扩大。最近，可见光通信已经被识别为被良好地装备以提供额外的带宽和系统容量，而不聚集移动的网络中的干扰。此外，节能的室内照明和大量的室内交通可以固有地结合起来。在这篇文章中，VLC被视为RF室内通信的一个可行的和现成的补充，并对未来通信的进步。各种应用场景进行了讨论，提出了支持仿真结果，目前的技术和挑战有关的VLC实现进行了调查。最后，最近VLC商业化的概述。
Due to the large growth of mobile communications over the past two decades, cellular systems have resorted to fuller and denser reuse of bandwidth to cope with the growing demand. On one hand, this approach raises the achievable system capacity. On the other hand, however, the increased interference caused by the dense spatial reuse inherently limits the achievable network throughput. Therefore, the spectral efficiency gap between users' demand and network capabilities is ever growing. Most recently, visible light communication has been identified as well equipped to provide additional bandwidth and system capacity without aggregating the interference in the mobile network. Furthermore, energy-efficient indoor lighting and the large amount of indoor traffic can be combined inherently. In this article, VLC is examined as a viable and ready complement to RF indoor communications, and advancement toward future communications. Various application scenarios are discussed, presented with supporting simulation results, and the current technologies and challenges pertaining to VLC implementation are investigated. Finally, an overview of recent VLC commercialization is presented.
