The visible light spectrum has a bandwidth that is 10000 times larger than the entire radio frequency and microwave spectrum. In establishments such as house or building, enabled LED lamps must be strategically placed in rooms, halls, and other sections to expand the scope of the Li-Fi network. It is important to note that some medical instruments used in hospitals, as well as the radar and communication systems in an aircraft are sensitive to radio frequency. Deploying Li-Fi is theoretically inexpensive because of the small cost associated with the production of LED lamps. It is 12 in the noon and you have a long meeting from 1 PM to say 6 PM. Since LEDs are semiconductor devices, the current and optical output can be modulated at very high speeds. That means you can only use it effectively in closed spaces. In the near future when the technology is already available to the general public, street lights, building lights, and transportation lighting can all communicate wirelessly and you can access the internet wherever you may be. Advantages of LiFi: 1. Physical barriers such as walls and doors limit the operational scope of a Li-Fi-enabled LED lamp. The Cons of LiFi. In other words, it’s a light-based Wi-Fi which uses light instead of radio waves to transmit information. A primary selling point of Li-Fi technology is that it has a faster data transmission rate than Wi-Fi. Security: One main advantage of Li-Fi is security. In fact, Researchers at the University of Oxford have claimed that they successfully tested an experimental Li-Fi application with a bi-directional speed of 224 gigabits per second. It was during his TED Global talk in 2011 that he brought LiFi into the public spotlight where he used a table lamp with a LED bulb to play video of a blooming flower that was then projected onto a screen. eBook topics. • The LiFi is the short form of Light Fidelity. LiFi is described as visible light communication technology that transmits data, like mobile communications, at high speeds through a light source (lightbulb). At this speed, a high-definition video can be downloaded in seconds! This means that a Li-Fi network can be integrated easily with existing LED lighting systems. As of now, LiFi cannot fully replace Wi-Fi as a connectivity source but in the future, pureLifi is developing it to be the dominant internet connectivity technology in the whole world. Every time we wanted to learn something, we have to know what are the pros and cons of how we must easily work that out properly. Public WiFi is a form of convenience that’s taken for granted these days. This advantage is the reason why proponents have banked on Li-Fi as a solution for resolving that issues involving the bandwidth limitations of Wi-Fi and the growing amount of data produced and consumed by users. It’s similar to WiFi technology in that WiFi also transmits data at high speeds, but LiFi uses light with a LED bulb, and WiFi uses radio waves with a wireless router. While Li-Fi definitely has a number of advantages over Wi-Fi, its pros and cons should still be reviewed. Also known as Light Fidelity, Li-Fi uses subtle fluctuations in LED light to tra… Here are its major advantages: Light waves are able to carry far more information than radio waves used in Wi-Fi technology since the visible light spectrum is almost 10,000 times larger than the spectrum occupied by radio waves.
