摘要：Communication through visible light (VLC) has been studied as an alternative of wireless communications for indoor environments principally due to recent development of LED’s high-brightness and potency which has shown great potential of lighting once they have a long life and a better luminous efficiency compared to the current methods of lighting. To verify the behavior of the optical wireless transmission a prototype was built wis possible to send and receive data through the visible light. Were used 50% and 100% levels of light intensity symbolizing the logical levels 0 and 1 respectively and it resulted in a 25Kbps rate. Were used components in red light region and a signal system of recognition was required to run at different distances and position angles.
