i2CAT participation in the Mobile World Congress 2017

i2CAT, the research and innovation center applied to Internet and advanced digital technologies, will be also this year showing its last developments and technological potential at MWC. Fully aligned with top themes identified for this year MWC edition, especially IoT and 5G.

  • VR-Go, The proof of concept shown at the stand is a solution that applies the visible light communications to the immersive virtual reality. This, makes VR more accessible and affordable, gives the user a more movement freedom and opens the door to better virtual reality experiences.
  •  i2CAT will be demonstrating its potential in 5G though the integration of 60 GHz backhaul radios developed by Bluwireless Technologies with an SDN controller developed by i2CAT.
  •  It will be also shown, together with Cellnex Telecom, a communication protocol V2X (vehicle to vehicle and vehicle to infrastructure) to demonstrate that use of communications technologies can improve the efficiency of transport systems (V2Arch).



The application of the SDN principles to wireless backhaul networks is one of the key enablers to unleash massive deployments of outdoor Small Cells in future 5G networks.

i2CAT will demostrate the integration of 60 GHz backhaul radios developed by Bluwireless Technologies with an SDN controller developed by the research and innovation center.

The key innovation point is adapting the radios to a wider rank. The radiosa re Connected to the last version of OpenDayLight, the Standard used in Software Defined Networks

This work has been fulfilled under the 5GPPP 5G-XHaul project funded by the EC.


V2Arch demostration

It will be shown the simulation of IEEE 802.11p protocol (protocol for wireless vehicular networks) which demonstrate the benefit of informing drivers much in advance of the presence of an ambulance. This gives the driver time to clear the space without obstructing it.

Up to know the drivers can hear the sirens and see the ambulance when the emergency vehicle is too close so the traffic jam is almost unavoidable. This, also weakens the response time efficiency of the ambulance.

This work has been developed for the project V2Arch leaded by Cellnex Telecom.


VR-Go Keep Moving in the Immersive Virtual World


Technology overview

Mobile-based VR devices (Google Cardboard, Samsung GearvR) show how mobile phones can be used for sophisticated VR experiences. However, mobile-based VR devices do not allow for volumetric tracking, which allows rendering a VR scene integrating head movements, beyond rotations.

We demonstrate for the first time volumetric tracking on mobile-based VR devices using Visible Light Communications (VLC). In particular, we position a VR headset taking advantage of an opportunity signal often available in a fair, exhibition or museum - the light emitted by a retro-illuminated stand to show information or promotional material.

Our system uses the camera of the mobile device to track modulated light signals generated by small-cost electronic regulators integrated with the light-emitting device. The volumetric tracking generated through this combination of available elements is fast and precise enough to integrate head movements within the usual VR rendering pipeline, with no specific hardware requirements (a 2-year old mobile device is used for the demo)

Demo Set-Up

Only 4 lights are needed for a full location (position and orientation). More lights provides more freedom.

  • New types of games where mobility (displacement) is introduced.
  • Multiple user environment with users  located in the same or remote place
  • Reproduce real scenarios on naked spaces, allowing the user to move as in the real one

Key Benefits

Full Immersive

Move along the virtual world, no just move your head.


As no central  element is used (just a WiFi access point) multiple user can share the same VR scenario.

No space limits

Any space can be used to setup de VR, it can be increased as more lights are added.


Just a mobile phone and at least four  LEDs lights with a simple switch.


Full processing done on the mobile, no cables or wireless connectivity  is needed.


Location refresh rate higher than 30 time per second with a precision of 10 cm in position and 3 degrees in orientation.
