LiFi Last Mile


Optiva Media collaborates with the Universidad Complutense de Madrid (UCM) in the definition, design and implementation of a working prototype of a LiFi communication system. The main goal is to demonstrate the applicability and viability of LiFi technology as a substitute or complement of WiFi technology to provide fast access to premium video contents in public transportation vehicles.

The technical objectives proposed for this project are:

  1. The development and construction of an electro-optical transductor
  2. The development and physical construction of a LiFi luminary (sender-receiver)
  3. The development and construction of an optoelectronic transductor which includes electronic reception and emission for the end user's device.
  4. The development and implementation of communication protocols for coding and decoding information.

The project is now under development with the following preliminar results:

  • We have performed a deep analysis of the existing State-of-the-Art related to Visible Light Communications (VLC) and LiFi.
  • We have defined and implemented a communication protocol for the LiFi system following the IEEE 802.15.7 standard.
  • We have designed and implemented the HW that modulates the light of the LEDs according to the information to be transmitted.

We are currently working on the implementation of the luminary subsistems for the transmission and reception of pulsed light at high speeds (in the order of 80 Mbps) and we expect to have the final prototype by the end of 2017.

Project oriented to an enhancement of user's experience in interactive video applications like virtualized games or applications in which it is expected a fluid user experience.

The aim of this project will be achieved by the research of new video coding technologies (Logarithmical Hopping Encoding - LHE), real time monitoring of network parameters (Q4S protocol) and dynamic quality assurance supply.

  • LHE: image and video coding technology which offers a very low computational complexity and a higher quality/bit rate comparing to other current technologies, which allow reducing coding time as well as reducing bandwith consume.
  • Q4S: real time network parameter measurement protocol, which provides alets of network status and potential quality degradation. This gives the operational elements that allow providing quality service (priority, bandwidth) dynamically on demand.

The ARQUEOPTERIX consortium is formed by seven companies: Nokia, Optiva Media, MasMovil, MashMe.TV, Brainstorm, Experis and TRC; and in collaboration with four research organizations: Tecnalia, Gradiant, Universidad Politécnica de Madrid (UPM) and Universidad Politécnica de Valencia (UPV).

The project it's now on its second year. We have implemented a first version of the Q4S protocol that was succesfully integrated with the GamingAnywhere platform to provide dynamic QoE in a cloud gaming environment based on QoS measurments. Additionally, we have proposed improvements to the Q4S protocol that will be submitted to the IETF for their approval. Finally, the consortium has implemented the first prototype of the LHE coder that allows to reduce the coding time of the video while reducing the consumption of bandwidth versus quality .
