Do you know about LiFi technology? LiFi stands for Light Fidelity and it is a reliable wireless technology. This technology uses light instead of radio waves to transmit data at high speeds. LiFi was first introduced by Professor Harald Haas in the year 2011 at a TED Global talk. LiFi technology is considered more secure than radio technology. It can provide much higher speed in mobile devices compared to WiFi.

LiFi has a lot of advantages over WiFi because with the help of LiFi technology, you can work in areas that are susceptible to electromagnetic interference like Hospitals, aircraft cabins, etc. and you also get higher transmission speed. Theoretically, LiFi can transmit at speeds of 100 GB per second. According to Professor Harald Haas, LiFi can be used in areas where the usage of radiofrequency is very dangerous. LiFi can provide internet access in areas where WiFi frequencies cannot reach.

The Li-Fi market size is currently growing and it is expected to grow even more in the coming times. There is a growing demand for indoor distributed networks and LiFi is the perfect option for it because it allows users to make calls and access the internet at high speeds. However, the implementation cost of LiFi is high.

LiFi provides a much bigger bandwidth because it uses ultraviolet, infrared, and visible light communication. Currently, LiFi technology is developed by numerous big organizations around the world because it has a lot of advantages over Wi-Fi frequencies.

How Does LiFi Technology Work?

how does li-fi technology work?

LiFi technology is based on the principle of Visible Light Communication that provides wireless internet communications at a very high speed.

LiFi embeds the data in the light beams, hence, when a light bulb is turned on it emits pulses of light and inside those pulses, data can travel to the receivers. These pulses of light cannot be detected by the human eye. Afterward, the transmitted data is received and the information is interpreted. The whole process is very fast and the LiFi technology speed can go over 100 GB per second. This is how it usually works.

Wireless data has become an essential part of our daily life. Mobile data traffic is continuously increasing at a very rapid pace. With more and more users of wireless network connectivity, we are getting closer to the spectrum crunch.

The lack of a sufficient wireless frequency spectrum is known as Spectrum crunch. That is why LiFi is important because it provides a lot more access points than radio frequencies and you will also get faster connectivity and transmission speed.

There are numerous benefits and advantages of LiFi technology. The data transmission will be way faster than the data transmission done using Wi-Fi. It is efficient as there is no extra cost of electronic devices like routers, modems, wave amplifiers, etc. involved in it.

LiFi technology is very secure compared to Radio waves as it cannot pass through opaque objects, whereas, radio waves can easily pass through walls and it is a huge risk to the security of the data.

Apart from this, the other major benefits of LiFi technology are reliability, low latency, bandwidth, localization, interference-free, etc. These are the benefits and advantages that you get with the technology of LiFi.

These are some of the LiFi products and apart from these, there are numerous other LiFi devices that are available in the market.

There are various uses of LiFi technology because of its features. As it provides high internet speed, you can use this technology in big shopping malls and as we know that it is not based on radio frequencies, you can also use it in airplanes, underground stations, airports, etc.

The high internet speed that LiFi technology provides is a huge boost for various live-streaming events like Conferences, Meetings, Seminars, etc. LiFi technology can be used in hospitals because there is no electromagnetic interference. It can be used to collect real-time data through the LiFi network over any LiFi-enabled device.

LiFi technology can also be used in schools because the use of technologies is increasing in schools and educational institutions and a seamless and fast internet connection will enhance the whole experience of smart technologies. Another reason for using LiFi technology in educational institutions is that radio waves have negative effects on children, whereas LiFi is healthier. It is believed that the future of home and building automation depends on LiFi technology because it is secure and fast. Apart from this, it will play a huge part in underwater applications, virtual and augmented reality, autonomous transport, and advertising. These are some of the major uses of LiFi technology that we can see in the coming time.

FAQs on LiFi Technology:

Is LiFi faster than Wi-Fi?
