Li-Fi technology is a way to use light for wireless communication. This means that data is sent from one place to another using LED lights. The flickering of the LED light is changed to convert the data into signals, and then these signals are received again through a light sensor (photodetector).
Li-Fi has several advantages over Wi-Fi. First of all, Li-Fi can be much faster than Wi-Fi. Li-Fi uses the light spectrum, which is 10,000 times larger than Wi-Fi, so Li-Fi has much more data transmission bandwidth than Wi-Fi. Li-Fi signals do not interfere with electronic devices, making Li-Fi technology the best option for use in hospitals and aeroplanes.
There are also challenges with Li-Fi technology. Li-Fi technology works in a clear line of sight and cannot penetrate walls or other solid objects. Li-Fi signals can be affected by ambient light, which can reduce their effectiveness.
Overall, Li-Fi technology is an exciting development in the field of wireless communication. Li-Fi technology can provide faster and more reliable internet connectivity and can become an important complement to traditional Wi-Fi technology.
