What is Li-Fi Technology

LED light bulbs take another step into the future. Have you heard of Li-Fi technology? Are you familiar with the term Li-Fi?  If not, I’m am going to do my best to shed some light on the new technology. Li-Fi technology puts a new twist on data transmission.

First, what is Li-Fi?

Li-Fi stands for Light Fidelity. It is a technology that is the wireless communication between devices using light to transmit data. Today, only LEDs are used for transmission of visible light.

light bulbLi-Fi was coined at the 2011 TEDGlobal conference in Edinburgh by Harold Haas. Harold Haas is from the University of Edinburgh and the Chair Professor of Mobile Communications and co-founder of pureLiFi. This where he first introduced the idea of “wireless data from every light.”

To be more specific, LI-Fi is a visible light communications system that is capable of transmitting data at high speeds over the visible light spectrum, ultraviolet, and infrared radiation.

The technology is quite similar to WiFi only 1,000 times the frequency spectrum of radio. Li-Fi is fashioned to use LED light bulbs like those currently used in homes and offices that are already embracing energy conscious awareness.

What Are The Advantages of Li-Fi

What are the differences of transmitting data over Li-Fi compared to WiFi? A fundamental difference is that WiFi uses radio frequency to send data. Li-Fi uses light. The main advantage is working across a higher bandwidth to transmit data.

Using a higher bandwidth allows Li-Fi to work in areas susceptible to electromagnetic interference with benefits of superior transmission speeds. Impressive data speeds up to 224 gigabits per second compared to WiFi.  Li-Fi makes an excellent choice for hospitals and aircraft cabins.

Li-Fi uses standard LED light bulbs to enable data transfer by using light. The technology could be the key to link the digital divide. Light Fidelity (Li-Fi) is bidirectional, high speed and thoroughly networked wireless communication technology comparable to WiFi.

The Li-Fi market is well on its way to compound its annual growth rate of eighty-two percent from 2013 to 2018. Also, to be worth just over 6 billion by 2018.

Li-Fi Is Faster and More Secure

Li-Fi is the latest method for data transmission. A French office is continually implementing the new wireless technology with extreme success.

Free Shipping LED High Bay Light for commercial or industrial lighting, e.g., warehouse, supermarkets, furniture store, gyms, garages.

The wireless technology uses a LED light fixture equipped with a modem. The modem makes the light flash at a pace faster than the human eye can detect. As the light flashes, the data is identified by a USB inserted into a tablet or computer.

An office that has Li-Fi will enjoy the benefits of energy efficient LED light bulbs, stable quality, highly secure connection, and speeds that are 10,000 times the spectrum of WiFi.

Testing Continues

The Phillips Lighting company is currently testing and researching Li-Fi. Phillips claims that as the technology gains popularity. It can be internally installed on most devices.

If Li-Fi (internet broadcasting through light) proves itself to be successful, we could see the start of speedier and safer data around the world.

Conclusion

The potentials of (Li-Fi) Light transmitting data is vast for the digital age. It is going to interesting to see how Li-Fi plays out in the future. I would love to hear what you have learned or heard concerning Li-Fi.

Thanks,

  1. So is Li-Fi more secure than WiFi as a result of light being restricted to with a confined space? (Unlike WiFi that can travel through walls)

    What kind of adapters are available for your computer to receive and transmit data? I would assume there is some kind of USB device you can plug in?

    This tech seems almost too good to be true! I’m very interested to learn more. Maybe you’ll have a deeper dive into setting up your network with this new technology some time in the near future?

    1. LI-Fi is in the early stages of development, but all indications are Li-Fi will be more secure than WiFi. Li-Fi will have a hub and you will have to have a USB plug that is compatible with the new technology. I am researching the new technology and will post as new data comes available.

      Thanks,

      Kevin
