Performance Analysis of Li-fi Communication System

Abstract: Li-fi is a promising technology in today’s communication system. It may bringup the many benefits over other communication technologies. Since light isthe main source to provide data, and this is available everywhere around, itmay compete with other technologies that use radio communication. Thistechnology is completely a new way of communication. Therefore, it isimportant to study firstly the literature review of this new and emergenttechnology. Besides, some prototypes are designed corresponding to this Li-fitechnology. Since Path loss is one of the most important effects in the worldof communication, therefore, a prototype is designed where a proposedmodel is showed which represents the path loss propagation model. There areother prototypes are designed in which a Li-fi communication system has beenestablished using ASK modulation technique, a prototype of Data transmissionby sending bits ‘1’ and ‘0’ using LED (Light-emitting diode) and finally aprototype of the demonstration of indoor navigation that is associated with thetransmitter and the receiver, and the receiver locates the desired places using serial communication.
