The state of the art on light connectivity

The Swiss Confederation, with its Federal Department of the Environment, Transport, Energy and Communications DETEC (Federal Office of Communications OFCOM, Licences and Frequency Management Division Radio Technology Section) made a report about uses and advantages of light connectivity.

Slux is reported as developer of solutions in this field.

Over the state of the art: Slux Technological Value

Slux research starts about 12 years ago with the first studies and experiments of light connection of Alessandro Pasquali. In those years, different systems and techniques of transmission has been widely tested. Today the systems work with light beams pulsed with specific modulations and algorithms according with the application requirements. 

It is important to note that Slux has not only one approach of transmission: we have the know how to develop different codifications and algorithms of transmission according with the result that we are interested to obtain.

The modulation of the light's carrier can be numeric or not and the transported informations can have different levels of the current cryptations solutions or costumized approaches of cryptation.

We are used to work with low power LED in all the wavelenght of the visible part of the spectrum and near infrared. We have also tested transmission systems based on OLED,  photovoltaic cells, flames, neon tubes and other plasmas.

The power of the single LED emitter can be from less than 0.1W to 100W.

About range in open space is more than 30Km (tested using a power of light emitted less than 0.1W).

Indoor we cover a range of about 10 meters without the limit of being in the optical view of the light emitter.
