First experiments for a Wi-Fi access in the tramway in Brest

Within the framework of ongoing project CapilRTram, the Optics Microwave and Network-Security-Multimedia Departments will assess the feasibility of a Wi-Fi access solution in mobility within the tramway carriages in Brest.

The proposed solution exploits a future-proof optical distribution network dedicated to the interconnection of tram stations with high capacity. Wi-Fi links at 5.8 GHz  compliant with the IEEE 802.11a standard provide communication between stations and carriages in motion. Wi-Fi coverage at 2.4 GHz in provided inside carriages in compliance with the IEEE 802.11 b/g standard.

The main problems to tackle range from radio engineering including (regulatory and propagation issues) to network aspects such as managing mobility by means of adapted roaming mechanisms. The use of radio modules embedded in the carriages will enable the minimisation of electromagnetic emissions and energy consumption of mobile terminals. 

At present, only three stations in the centre of Brest (Château, Siam, Liberté) and two carriages have been equipped.  The first experiments  will take place onboard between February 20 and March 20, 2014 to test the solution under real conditions. 

This project is carried out in close collaboration with ALSTOM, KEOLIS, MOXA and with the support of  the municipility of Brest (BMO). It draws upon the  experimental platform CapilR specialising in  Radio-over-Fibre and All Optical technologies for wireless access. It gave birth to several student projects for research and education purposes.

Du WiFi dans le futur Tram (Brest)
Le Télégramme - 15 Juin 2011 à 17h04Agrandir le texte

En marge d’un colloque sur les technologies vertes radio-sur-fibre, l’école Télécom Bretagne présentait, hier, un dispositif prometteur unique en France. Ce projet baptisé « Capil’R Tram », permettra d’offrir un accès WiFi aux utilisateurs du tramway brestois. Les discussions pour déployer cette technologie sur le futur tramway brestois seraient déjà bien avancées avec Brest Métropole Océane. Les premiers essais sur le terrain sont envisagés pour septembre 2012.

Les applications envisagées par Télécom Bretagne ne se limitent pas qu’à l’utilisation d’internet en situation de mobilité. Ce réseau mêlant un câblage en fibre optique le long du trajet du tramway et de nombreuses bornes offrant un accès sans fil pourrait également permettre de retransmettre les vidéos générées par « l’arbre emphatique », l’œuvre d’art du Barcelonais Éric Ruiz Geli qui verra le jour pour le lancement du tram, rue de Siam.

Projet CapilRTram : le WiFi dans le futur Tramway de Brest
Ouest France - 15 Juin 2011

Le département d’optique de Télécom Bretagne travaille depuis 2008 sur la plate-forme CapilR, chargée d’offrir la meilleure couverture wifi possible aux Brestois, par le système de la fibre optique. Depuis quelques mois, les ingénieurs travaillent sur un projet issu de cette plate-forme, le projet CapilR Tram, en accord avec Brest Métropole Océane, qui a déjà installé des bandes de fibre optique aux abords des stations.

« CapilR Tram permettrait d’assurer une connexion wifi aux futurs usagers du tramway, explique Frédéric Lucarz, ingénieur de recherche au sein du département optique et en charge de la plate-forme CapilR. Tant dans les rames, qu’aux alentours des stations. » Les usagers pourraient alors obtenir, en se connectant, des informations culturelles comme « des expositions », mais également économiques. « Ils pourraient recevoir des offres promotionnelles des magasins devant lesquels leur rame passe ».

La difficulté est qu’il faut « assurer une communication wifi entre une rame en mouvement et les stations, qui elles, sont fixes ».

Les ingénieurs du département d’optique de Télécom commenceront les premiers tests hors laboratoire vers septembre prochain.

6 high-definition video streams were transmitted simultaneously from a video server (left) to a client machine (right). Transmission was performed over a 10-km single mode fibre (SMF) link followed by a 2.5m optical wireless path using infrared lightwave at 1550nm. Commercially-available optoelectronic transceivers including a laser source and a photodiode were used for converting the signal from the optical domain to the electrical domain and vice-versa.

Brest, 26-27th October 2005

Technologies and architectures for all-optical telecommunication networks have been a topic of intense research for more than ten years now, dealing with issues such as : optical transmission at the physical layer, optically transparent network areas, protection and restoration schemes, multiple switching granularity (i.e. WDM and OTDM) and inter-networking between transport and control layers. While optical WDM transmission has been shown to be efficient and cost-effective in long-haul links, the situation is different in metro and access networks, where the unpredictable nature of traffic demands as well as more stringent economics and competing technologies have precluded wide-scale deployment of optics in these areas. The e-Photon/ONe field of activities is a good illustration of this wide spectrum of knowledge and expertise. This European network of excellence involves about 40 institutions including universities, research centres, operators and manufacturers to promote research and education integration in optical networking in Europe.
