Li-Fi Technology - The Newest Wireless Network

Li-Fi, short for Light Fidelity, is the newest wireless network that will allow us to send information with the help of light. Imagine being able to surf the web by just shining your light on! Unlike Wi-Fi, Li-Fi technology does not use radio when sending signals. Instead, it was made by waves.

The term was first used in 2011 by a professor at the University of Edinburgh, Harald Haas, during a speech on Visible Light Communication at TED Global, the annual American conference dedicated to innovation and creativity.

Li-Fi, visible light communication based on LED technology. Li-Fi is, therefore, a form of visible light communication traceable to optical wireless communications (OWC).

Characteristics:

 Its unique characteristics are data transmission speed, wireless connection in the absence of radio waves, extreme security, and accuracy, this technology could soon replace Wi-Fi technology in many applications, especially indoors.

Advantages:

The advantages of Li-Fi over Wi-Fi are considerable. Li-Fi offers:

  • Higher bandwidth.
  • Better efficiency.
  • Availability.
  • Security.
  • Faster data transfer.

 Wi-Fi is unable to support further traffic increases. Conversely, Li-Fi could play an important role in meeting the growing demand for data. The spectrum of visible light is 10,000 times larger than the entire radio spectrum.

 In addition to higher bandwidth, Li-Fi can achieve data rates over 10Gbps, proving much faster than Wi-Fi.

Li-Fi prepares to become the platform for a new digital age powered by billions of connections through light.

Some Benefits of Li-Fi Over Wi-Fi:

Availability:

Radiofrequency used in Wi-Fi networks is drying up the spectrum. Soon, it will not be enough to match the amount of food that continues to increase every day. In this case, Li-Fi is very useful for us. It uses a light bulb to emit signal radios, and there seems to be no light bulb soon.

Li-Fi allows you to view the web with any type of light. Under the sea, where Wi-Fi cannot work while radio waves are sucked into the water, Li-Fi can work because light can penetrate the water easily.

Speed:

Li-Fi technology is very fast. Light waves can carry more data than wave radios, and therefore, Li-Fi aims to transfer 224 GB of data per second.

Price:

Li-Fi is best, considering it doesn’t need a modem, router for its connection. 24/7 power is required for these devices to operate, but Li-Fi requires light bulbs with enough power to operate properly.

Disadvantages:

 There are some disadvantages of Li-Fi, such as its comparison to most devices or its low quality. But considering the newness of this network for everyone, first launched in 2011, a lot of work still needs to be done to make this technology complete and usable for more people.

It has been being tested for years in many labs around the world what could be the technology to replace the current 4G and Wi-Fi.

Conclusion:

 Li-Fi technology will allow for the lighting of a flashlight so that now comes together 90% of the lights that are in our lives today and that day information is transmitted to be recorded and altered by machines and records, images and even audio.
