What is Li-Fi Technology and How Does It Work?

Li-Fi technology, is an abbreviation for Light Fidelity and is a technology that uses light to transmit data in wireless communication. Its basic principle is to encode and transmit information using the visible light spectrum. This technology works by rapidly turning LED (Light Emitting Diode) lamps on and off. While the human eye cannot detect these rapid changes, a special receiver perceives these light signals and converts them into data. In this way, wireless communication is established via light instead of radio waves like Wi-Fi.

The working principle of Li-Fi is quite simple. An LED lamp represents data with its on and off states. These states represent 1s and 0s respectively, i.e. binary code is used. Data is transmitted by the LED lamp by flashing very quickly. A receiving device detects these light signals and converts them into electrical signals via a photodetector. These signals are then decoded to obtain the original data. This process can be repeated millions of times per second, which provides high-speed data transmission.

One of the biggest advantages of Li-Fi technology is, It eliminates dependence on radio frequencies.. This feature provides a great advantage in environments where electromagnetic interference can cause problems, such as hospitals, airplanes and petrochemical plants. In addition, the fact that light cannot pass through walls also provides a significant advantage in terms of data security. It ensures that data remains only in a certain area, making unauthorized access difficult.
