Este trabajo presenta una revisión general e introductoria de la comunicación de luz visible. La comunicación con luz visible o VLC (por sus siglas en inglés) se refiere a las comunicaciones inalámbricas que utilizan un rango espectral de 380 a 780 nm para la transmisión de información. Esta parte del rango óptico-electromagnético presentaalgunas ventajas para las tecnologías de radiofrecuencia inalámbrica actuales, así como varios desafíos para su desarrollo y aplicación. Se han desarrollado diferentes sistemas de comunicación de luz visible para el ámbito interior, exterior, doméstico e industrial, donde la luminaria realiza dos tareas: iluminación general y transmisión de datos, ya que este tipo de comunicación tiene importantes y valiosas aplicaciones. Recientemente, se han realizado investigaciones para mejorar el desempeño de cada bloque funcional que compone este tipo de sistema de comunicación. El VLC de incursión plantea desafíos como el ancho de banda de LED limitado por la vida útil del operador, la linealidad del controlador de LED, su enlace ascendente; la infraestructura de iluminación general a internet, y el rendimiento de la iluminación general y de atenuación. Se concluye que la incursión del VLC en el ya extendido espectro de los sistemas de comunicaciones inalámbricas complementará y hará menos nociva para nuestro medio ambiente, ya que la regulación internacional ha ayudado a mejorar sustancialmente esta tecnología.
This work presents a general and introductory review of visible light communication. Visible light communication or VLC refers to wireless communications using a spectral range from 380 to 780 nm for the transmission of information. This part of the optical-electromagnetic range presents some advantages to current wireless radio frequency technologies, as well as several challenges to its development and application. Different visible light communication systems have been developed for indoor, outdoor, domestic, and industrial fields where the luminaire performs two tasks: general lighting and data transmission, since this type of communication has important and valuable applications. Recently, research has been performed to improve each functional block’s performance that composes this kind of communication system. The incursion VLC poses challenges such as LED bandwidth limited by the carrier lifetime, the LED-Driver Linearity, it’s up-link; the general lighting infrastructure to the internet; and the dimming and general lighting performance. It is concluded that the incursion of Visible Light Communication into the already extended spectrum of wireless communications systems will complement and make it less harmful to our environment as international regulation has helped to improve this technology substantially.
