Implementation of In-flight Entertainment System Using Light Fidelity Technology

We are often directed to switch off our mobile phones and other electronic devices while traveling in a plane due to the interference caused by the radio transmitters installed in these devices. As a result, most customers do not enjoy the benefit of data on-board except for some airlines who provide the paid data services. Also, due to the recent outburst in the demand for data, there is soon going to be a congestion of the radio frequency bands. Thus, developing a technology which can entirely replace the current system of radio frequency-based data transmission is beneficiary [1]. Light fidelity (Li-Fi) is a next-generation technology which uses visible light as a medium for transmitting data [2]. Thus, it serves this increasing demand for data due to its vast bandwidth and does not interfere with airplanes as well. This paper aims on demonstrating the application of light fidelity (Li-Fi) in the entertainment services provided inside the airplanes. All the fundamental principle of visible light communication (VLC), the modulation techniques involved as well as how a circuit can be realized for transmitting data in an airplane using those principles have been discussed in this paper. Light fidelity (Li-Fi) when used to its full potential can certainly prove that everyone can count on it when RF fails to serve the purpose.
