Optical Communications over Lighting LEDs as the Basis for Information Networks

The purpose of this project is to provide visible LED-based lighting systems with new capabilities as information emitting devices so as to enable their use as emitters in communications networks.

The main goals this project aims to achieve are:

  • Characterization of emitter sources (reviewing different alternatives such as phosphor encapsulated diodes or RGB LED arrays) and receivers (both direct and diversity). Channel estimates will also be studied (by calculating coverage areas according to service quality limitations), as well as the characterization of the main noise sources.
  • A series of link prototypes will be designed, implemented and validated both as main visible links and command links, with different modulation/coding alternatives and different transmission rates.
  • Seeking application environments for this technology (in fields such as tourism, home automation, security and defense networks, aviation systems or communications in open areas or with high levels of EM noise). Encouraging the transfer of the technology generated by this project.
