LiFi (Light-Fidelity) or Visible Light Communication (VLC)
is a revolutionary communication technology that transmits data over visible light wavesEnter your text here...

How Does it Work?

Smart Surface

A driver converts the visible light waves produced by LEDs into electronic signals, then sends them to a photo detector. That signal is then decoded into an audio, text, or video file on a computer or connected device.

LiFi’s Many Advantages

> Secure data transmission
> No radio spectrum congestion and no license needed: 2.4 GHz and 5 GHz bands are often congested in public places, whereas LiFi uses bandwidths that are freely available
> Ecological and Economical: LiFi can work over the existing lighting network
> Astonishing speed of data transmission, similar to fiber optic cables
> Health: LiFi does not use electromagnetic waves


> Location Based Services (LBS): LiFi guides and informs you in parking lots, shopping centers, museums, airports, train stations, cities, and more.
> Electromagnetic sensitive places: LiFi provides safe internet connection in hospitals, schools, factories, and in aircraft.
> Shopping 2.0: in addition to i-beacon and WiFi, LiFi updates you on the latest sales and gives you information on the product in front of you.
> SmartCities: through the public lighting system, city governments can interact directly with inhabitants and provide them with relevant information, right where they need it.

Our Wysips® technology is a photovoltaic material so it acts as a photo detector and LiFi receiver.

Using a Wysips® component as LiFi receiver rather than a photodiode has many advantages:

> Wysips® is thin and transparent, so it’s easily integrated into any product.
> Wysips® easily catches the light; it does not have to be placed directly under the light source to receive data.
> Wysips® receives data even in strong sunlight.
> Wysips® LiFi basically powers itself—it both charges the device and receives data using visible light waves.

Our tests show that our Wysips® component can now receive data at a rate of several Mbit/s—meaning videos can be transmitted over light waves!
