  1. Visible Light Communication

  2. Introduction of Visible Light Communication The Visible Light Communications Consortium (VLCC) which is mainly comprised of Japanese technology companies was founded in November 2003. The work done by the VLCC is split up among 4 different committees:

  3. 1. Research Advancement and Planning Committee This committee is concerned with all organizational and administrative tasks such as budget management and supervising di_erent working groups. It also researches questions such as intellectual rights in relation to VLC.

  4. 2. Technical Committee The Techincal Committee is concerned with technological matters such as data transmission via LEDs and uorescent lights. 3. Standardization Committee The standardization committee is concerned with standardization efforts and proposing new suggestions and additions to existing standards.

  5. 4. Popularization Committee The Popularization Committee aims to raise public awareness for VLC as a promising technology with widespread applications. It also conducts market research for that purpose

  6. Every kind of light source can theoretically be used as transmitting device for VLC. However, some are better suited than others. For instance, incandescent lights quickly break down when switched on and off frequently. These are

  7. thus not recommended as VLC transmitters. More promising alternatives are fluorescent lights and LEDs. VLC transmitters are usually also used for providing illumination of the rooms in which they are used. This makes uorescent lights a particularly

  8. popular choice, because they can icker quickly enough to transmit a meaningful amount of data and are already widely used for illumination purposes. However, with an ever-rising market share of LEDs and further technological improvements such as higher brightness and spectral clarity

  9. Definition of Visible Light Communication VLC systems are presently being developed by scientists seeking to create ultra high-speed, high security, biologically friendly communications networks that allow the creation and expansion of seamless computing applications using very large bandwidth high-frequency pulsed light instead of radio waves and microwaves.

  10. Visible light is a range of electromagnetic radiation that can be detected by the human eye. The wavelengths associated with this range are 380 nm to 750 nm. (1 nm = 10-9 m)
