AB  - Recent years, the idea of ubiquitous computing or networking is attracting much attention. The wireless communication technology has demonstrated tremendous growth, and the numbers of mobile users also have increased rapidly over the past decade. The exhaustion of frequency resources has been a problem and utilized frequency bands are becoming highly allocated. As a method of realizing high speed wireless networks, the optical wireless communication systems are capturing the spotlight, on the other hand. Meanwhile, LiFi(Light Fidelity) based on white LEDs has emerged as an eco-friendly IT green technology using unregulated THz visible light spectrum in provision of both lighting and wireless access. In this paper, the key ideas on visible light communication (VLC) have been reviewed in relationship with optical wireless communication. The standardization activities and the applications are summarized. It also deals with the technical specifications including channel model for constructing a VLC PHY layer prototype.
