It is a very interesting concept. It is a High-Speed Optical Wireless Technology. LiFi is a full form of Light fidelity. If we look at the diagram, we understand where the radio waves and the visible waves stand. Overview of LiFi companies. This technology is called SIM OFDM. This also makes it possible for smaller modems to be directly integrated into a bulb. This would then combine two basic functionality – illumination and wireless data transmission. typically implemented using white LED light bulbs at the downlink transmitter Utilization of these wireless communication has become such a great part of life, that we need it every day. While WiFi offers a wider range of data transmission, LiFi operates in a smaller range. LiFi comprises of multiple light bulbs that form a wireless network. The data transmission of this technology can be done through illumination. In WIFI we need a modem to access the internet. This is where the big problem arises, the concern of capacity. This creates a vast problem in the supply and demand chain. HISTORY - The technology truly began during the year 1990’s in countries like Germany , Korea and Japan where they discovered LED’s could be retrofitted to send information . You can set up a LiFi enabled military tent at a remote location without the need for complicated wiring equipment. Imagine a world where every one of the billions of light bulbs in use today is a wireless hotspot delivering connectivity at speeds that can only be dreamed of with Wi-Fi. LiFi or Light Fidelity is a visible light communications system and the speed of this system is very high. Prof. Harald Hass from university of Edinburgh. On the other hand, the usage of these wireless signals has been increased by 5 billion and still increasing. As data travel only through illumination, no chances that other person would interfere with the data. LiFi technology for “Light Fidelity” is a new method to connect wirelessly mobile devices and other connected devices using LED lights. These 1.4 million cellular radio masts or base stations consume a lot of energy. LiFi is a technology for wireless communications between devices using light to transmit data. One significant question comes up in our mind. We are surrounded by LED lights at Hospitals, Flight Cabins, Street Lamps, Car’s LED Headlight, Mobile LED Flashlight and much more. LiFi full name is Light Fidelity. PLC or Ethernet is used to transmit the data from the LED to the internet router. By the help of this technology, instead of a single stream, thousands of multiple data stream can be transmitted at a single time and higher speed. As user demand for more data rises, the technology integrated in LiFi equipment adapts to it. Unlike WiFi, which uses radio waves to wirelessly transmit data, LiFi uses light; by modulating the intensity of a light source faster than the eye can see, the required information can be embedded and streamed to a receiver. What do we mean by 10K times the radio wave spectrum? The answer is yes, but one can dim the light to an access that it appears to be off. Any area that is illuminated is able to receive the signal, but the transmission is stopped by opaque objects such as walls. Image Credit: PureLiFi When a constant current is applied to an LED (LED lamps are commonly found in households and offices nowadays), tiny packets of energy (called photons) are released, which we perceive as visible light. Li-Fi system mainly includes two parts namely the transmitter and receiver. LED is a semiconductor device, with a switching on-off ability at very high speed. LiFi Technology. Do we have to keep the light ON all the time to keep LiFi working? Tomorrow may be some other technology which is more reliable, more effective than WIFI.
