CITI Talk: “Visible Light Communication for the Internet-of-Things” by Stefan Mangold, on 29th April

The next CITI talk will take place on the 29th of April at 11 am. This talk entitled “Visible Light Communication for the Internet-of-Things” will be presented by Stefan Mangold, founder of Lovefield Wireless (Switzerland) and associate professor with ETH Zurich.


Visible Light Communication (VLC) with Light Emitting Diodes (LEDs) as transmitters and receivers enables low bitrate wireless adhoc networking, which is an interesting approach for consumer electronics such as toys and related applications in the entertainment industry. LED-to-LED VLC networks with VLC devices communicating over free-space optical links achieve a throughput of a few kilobit per second at distances of up to ten meters. LED-to-LED VLC networks are useful for combining light bulbs and illumination with low-complex networking. In this talk, we present recent research achievements in this field, address open challenges, and demonstrate the performance of a software-based VLC physical layer and a VLC medium access control layer that retain the simplicity of the LED-to-LED approach.
