LiFiNET

LiFi? How your LED desk lamp could help you connect to the Internet.

14 billions of light spots in the world that could be used to create the 3rd generation of wireless telecommunication network.

Li-Fi doesn’t just use any old incandescent light bulb. Rather, it utilises LED lights, due to their ability have their intensity modulated at very high speeds. This enables them to transmit data, which can then be picked up by a light detecting receiver.
It’s a similar principle to the wifi emitter, only much faster and with much more data bandwidth.
The other benefit of this is that the LED lights could continue their primary function of illumination whilst transmitting data. The speed of the modulation we’re talking about here ensures that they won’t visibly flicker or flash, but will appear to offer consistent light levels.
Conversely, when no illumination is required, the light can be dimmed to an ultra-low level, and will still be able to transmit data.

HOW FAST?

We reached internet connection speeds of up to 1Gbps – that’s 100 times faster than standard Wi-Fi.

Meanwhile, in laboratory conditions, it’s been established that Li-Fi could theoretically reach speeds of up to 224Gbps.

SECURITY

Using light for our wireless data transmissions also has positive security implications. As light doesn’t penetrate through walls, and can be very finely focused, it would be tricky to intercept a Li-Fi data stream simply by lurking outside.
