Abstract
Visible light communication has come a long way from its use in traffic signals, marine signals and photo phone since Herald Haas demonstrated concept of technology which can communicate as well as illuminate, referred to as Li-Fi or Light Fidelity. Li-Fi emerged as a solution to the growing congestion problem on existing radio spectrum used by Wi-Fi. It offers inherent advantages like security, nonhazardous, availability, bandwidth, efficiency, and SPEED. Li-Fi has come a long way offering numerous applications in varied areas like intelligent transport system, underwater communication, traffic management, disaster management, smart lights, and data transmission in petrochemical industries, hospitals, and aircrafts. This paper presents an application of Li-Fi technology with augmented reality providing OnLight data communication to facilitate the information broadcasting of the exhibits in an exhibition to the mobile phone of the visitor. The proposed model consists of LED lights installed besides the exhibit and a photoreceptor installed at the mobile phone. As soon as the visitor aligns its mobile phone to the exhibit, all the supplementary information about it in the form of text, images, or videos gets downloaded into it. The proposed model offers faster transmission of data with no interference between devices and with other devices using radio waves. The transmission can be accessed anywhere with no dead zones which exists in its counterpart Wi-Fi. Above all it also provides energy friendly illumination because the LEDs would also provide illumination. The model can be used to identify the most and least accessed exhibition areas and items which would help in administrative decision.
