Abstract—The revolution in multimedia devices has promoted indoor wireless communication in the last decades. Wireless fidelity (Wi-Fi) connections have expanded rapidly, and more than 5 billion devices have been connected to Wi-Fi each day since 2013, which causes system overloading. This bountiful usage of wireless devices has consumed an excessive amount of the radio spectrum, and the current standard for wireless communication is not able to provide enough capacity for indoor wireless traffic in the next decade. Wi-Fi currently holds 60% of the global traffic; however, secure communication for the internet of things (IoT) and spectrum congestion are two significant challenges for future communication development. Therefore, an affordable, secure, and fast medium for wireless communication is in urgent demand. It should be noted that the spectrum provided by visible light communication (VLC) can be thousands of times wider than the radio frequency (RF) spectrum. The challenge of spectrum congestion and the urgent demand for a high-speed medium can be solved through the application of visible light for indoor communication. It has been proved that each user can achieve a data rate of hundreds of Mbps in the congestion scenario through the application of VLC. But beside these advantages Li-Fi also have some limitations like unavailability in excess and in low light and also limited coverage due to walls and etc. To overcome these limitations the Wi-Fi and VLC hybrid network can be a good solution to continue using privileges of both technologies. A lot of research has been done to introduce a numerous techniques for such hybrid network but we are proposing Auto channel switching unit in this system which will be responsible for shifting and sharing data traffic on both Li-Fi and Wi-Fi channel.
