LiFi is an acronym for “Light Fidelity,” which stands for “Visible Light Communication,” a technique that enables wireless data transfer using LED light bulbs. Harald Haas, a professor at the University of Edinburgh, was the one who came up with the idea for it in 2011. In this post, we will investigate the functionality of Li-Fi, as well as its advantages and uses in our day-to-day life.
How does LiFi work
The primary distinction between Wi-fi and Li-fi lies in the fact that Wi-fi sends data via the use of radio waves, whereas Li-fi sends data through the use of visible light communication. Modulating the intensity of the LED bulb that is included within the transmitter causes it to create binary digits. These digits are then sent to the receiver, where they are decoded in order to obtain the desired information. This modulation may be done quickly, resulting in speeds that are far greater than those achieved by wi-fi. Beginning in the year 2022, regular people will be able to use LiFi technology.
Using LiFi, the retailer determines the customer’s position within the store and then sends them relevant coupons and other incentives based on that information. LiFi capabilities are also being considered by a number of prominent mobile businesses, including Apple, amongst others. LiFi collaborates with partners in a wide variety of industries, including the military industry, healthcare, the lighting industry, information technology infrastructure, telecommunications companies, and device integrators.
What are the most significant benefits of using LiFi?
In our day-to-day lives, we are completely reliant on wireless data. Wi-Fi service will, alas, be discontinued at some point in the future. The radio frequency spectrum is becoming increasingly scarce as a result of the ongoing digital revolution. The term “spectrum crunch” is when there is a shortage of a certain type of radio frequency because more people are using wireless connectivity every year.
As there is a shortage of wireless frequency spectrum, a growing number of consumer electronic gadgets may be impacted by a spectrum crunch. This may be the case because there is not enough spectrum available. Spectrum crunch is a threat that might have significant repercussions for the near future, as it threatens both cellular networks and telecommunications infrastructure.
Wi-Fi will not be able to keep up with the growing demand for data, and worldwide networks will need to be future-proofed in order to satisfy the requirements of today. When compared to radio frequencies, our potential to exploit spectrum with LiFi is more than one thousand times greater. Because there are more access points available, LiFi is able to reach better data speeds. Additionally, the radio frequencies used by LiFi result in the production of tiny cells, which facilitate speedier connections.
