VLC and radiometry laboratory



Data transmission with light (VLC Visible Light Communication) is an important technology whose significance is growing rapidly. High data rates can be transmitted and VLC can be used for precise positioning (indoor navigation). At the same time, lighting units can be networked wirelessly and tap-proof with this technology.

We develop indoor and outdoor lighting units and integrate VLC technology into them. The data transmission (rates reach up to the GHz/s range) and the position determination are carried out according to the IEEE 80215.7 standard. We develop the VLC luminaires customer-specifically depending on the applications, as well as the modulation technology (OFK, CSK, OOK) and the data rates. The receivers can also be integrated into the luminaire and are developed by us.
