A Performance Enhancement for Ubiquitous Indoor Networking Using VLC-LED Driving Module
This study aims to use LED, a representative runner in electric energy reduction as Green IT technology in the field of lighting and suggest visible communication for using ubiquitous Indoor networking system. As LED is excellent in its efficiency, the aim has to use such LED to access ubiquitous environment, a network that can be used remotely at any time anywhere and determine the possibility of its application into various applications that promote users’ convenience. The communication performance by implementing a communication system for lighting in order to send a text message has been tested in ubiquitous environment within ~2.5m, 0.45V, 5% error rate, data rate Kbps and within disturbance light. We could confirm that the implementation of LED communication was possible in ubiquitous environment within ~2.25m, data rate ~Kbps, and 3% error rate, or more was weak or none where data transmission is seamlessly done indoors.
