“…Also, the light is generated in the case when particles that are carrying current (holes and electrons) are combining in the material in semiconductor, while the light wasn't explicitly bright, yet it was monochromatic in the majority of LEDs that happen at a single wavelength [32]. In comparison to Infrared Radiation )IR( LED producing a single data stream with 10kbps -20kbps speed, such LEDs are generating thousands of data streams that spread through the room, in which the light might be reaching extremely rapid rates [9]. Via utilizing certain techniques of Luminaire Design Optimization, the possibility of such LED might be increasing.…”

“…Via utilizing certain techniques of Luminaire Design Optimization, the possibility of such LED might be increasing. The R&D center related to pure VLC has lately achieved a 3.5Gbps data rate from single color micro-LED operate at 5 mW with a distance of 1m and 1.1 Gbps as data rate at 10 m and 5 mW [9]. Therefore, it might be indicated that data rates of over 10 Gbps might be reached via utilizing 3 Red Green Blue (RGBO LED colors [33].…”

Wireless Fidelity (Wi-Fi) is particularly popular today. Every place has hotspots to access the internet via Wi-Fi, including homes, offices, colleges, and other public places. This increased number of users, and hence the use of bandwidth, has led to radio spectrum congestion. Thus, in the year of 2011, Light-Fidelity (Li-Fi) was introduced, which applies a visible light region for data transmission, to solve this radio crisis problem. This visible part of the spectrum was 10,000 times big compared to the part utilized in the Wi-Fi radio. Furthermore, Li-Fi was a sub-set of Visible Light Communication (VLC), using Light-Emitting Diode (LED) bulbs for transmitting data utilizing light-medium. This paper reviews the differences between Li-Fi technology and wireless types. It Also focuses on the architecture, components, functioning, modulation technologies, and applications of Li-Fi.
