Using Mobile Phone Based Camera to Read Information from a Li-Fi Source

摘要

At crowded events, an increasing number of people use their mobile devices at the same time to run applications having high data requirements leading to network congestion. This paper investigates the use of LED light to act as a Li-Fi source in order to transmit data. The data is captured using the CMOS camera of an Android smartphone. The experimental setup is tested using two different Android devices and the results are compared.
