Internet at speeds of 1Gbps by use of LED bulbs

19 comments

Imagine a technology, which could connect you to the Internet at speeds of 1Gbps, by simply using LED bulbs, free from any waves with potentially harmful effects on the body.

That is precisely what Li-Fi offers. It is a technology in the development phase and is planned to be used first in businesses and then in homes.

Li-Fi, which stands for Light Fidelity, is a wireless communication technology based on the use of the light spectrum.


It sends data by switching the current to LEDs off and on at a very high rate, and is invisible to the human eye.

Safe technology


Li-Fi has many advantages, starting with the absence of radio waves, which could be harmful to health in the long term, and electromagnetic interference.

Also, the Li-Fi spectrum is around 10,000 larger than Wi-Fi’s, making it possible to connect more users together at the same time.

Furthermore, as light cannot pass through walls, there can be no automatic connection from one room to another. But it also means that piracy from outside sources becomes impossible.

In terms of speed, Li-Fi looks highly promising. It could theoretically achieve speeds of 1Gbps, which is faster than the most recent Wi-Fi standard (802.11ac).

Researchers at Oxford University in the UK have achieved speeds of 224Gbps in the lab, which is a record, but it is not likely to become the norm in homes.

In France, several Li-Fi connection experiments are currently underway, mainly in business settings led by specialist companies such as Oledcomm and Lucibel. Velmenni, an Estonian start-up, has already carried out tests in homes.

One of the preconditions for Li-Fi to become commonplace is for the whole environment (companies, public places, housing, etc.) to be equipped with LEDs and for mobile phones to have light sensors compatible with this new technology.

    Excellent, i appreciate it, i guess we shall need optical fibres communication systems. Advantages of physics radiation from matter, light amplification by stimulated emission of radiations.

    Interesting! I wonder how “safe” it actually is…

    so, if i have several led bulbs at home that are connected to the LI-FI, and my laptop has LED sensor attached into it, so therefore, I can transfer and receive files as long as my laptop is within the range of visible lights coming from the LED bulbs I have at home?

    This link has a virus, don’t open it. my antivirus is showing that, and it’s correct always.

    The link to the article? if your anti-virus report it as virus, you’d better change anti-virus software. There is no viruses on the site. It’s being scanned daily for anything suspicious.

    well my antivirus isn’t wrong, it has virus, malicious content

    Sucuri security scanner is doing a manual check right now to check if any plugins is causing the warning. It will report to the vendors of anti-virus software when it’s done scanning. Thanks for telling though.
