Today, Tuesday March 28, TDF starts broadcasting DAB+ digital radio from its Cesson-Sévigné (Ille-et-Vilaine) site.
The population of the Rennes conurbation can now receive thirteen radio stations broadcast in DAB+ digital quality: Africa Radio, Canal B, Chérie FM Rennes, C'Lab, Euradio, Inrocks Radio, NRJ Rennes, Océane, Quartier des Ondes, Radio Caroline, Radio Laser, Radio Pitchoun and Radio Rennes.
To enable these radios to be broadcast in DAB+, TDF teams installed new technical facilities. The work involved installing a new antenna system, a multiplexing cell and an associated transmitter. Work was also carried out to adapt the infrastructure of the TDF tower at Cesson-Sévigné.
In addition to broadcasting DAB+, the TDF site at Cesson-Sévigné also broadcasts FM radio and hosts cell phone operators.
TDF dispose d’un ancrage territorial historique à Rennes et y développe des innovations de très haut niveau depuis plus de 40 ans. Le centre d’expertise de TDF de Cesson-Sévigné rassemble des savoir-faire pointus dans les domaines de l’audiovisuel, en particulier du DAB+, des systèmes de diffusion et de télécommunications mais aussi de l’énergie, notamment renouvelable, de la maîtrise des consommations et du génie climatique.
De plus, le Centre de mesures d’antennes de TDF, situé à Liffré près de Rennes, dispose d’une expertise de très haut niveau dans la conception de systèmes antennaires complexes.
Ces centres d’expertise accueillent des ingénieurs dont les compétences sont essentielles pour la conception et la maintenance des réseaux et des sites de TDF. La ville de Cesson-Sévigné abrite aussi le siège régional de l’activité nord-ouest des opérations de TDF. Par ailleurs, TDF est co-fondateur et membre historique de l’Institut de Recherche Technologique b<>com, également basé à Cesson-Sévigné.
TDF, committed to DAB+ technology
As the benchmark technical operator for terrestrial television and radio broadcasting, TDF has been involved in the development of DAB+ for many years. TDF's laboratories in Rennes were instrumental in defining and standardizing this technology. Today, TDF is mobilized for the deployment of DAB+ broadcasting services in mainland France.
DAB+ (Digital Audio Broadcasting) is a digital terrestrial broadcasting system for radio, similar to DTT for television. It enables radio stations to offer listeners high quality sound, but also to transmit additional information and visuals in addition to the audio stream. This technology, which complements FM broadcasting, enriches the French radio landscape.
To receive DAB+, you need a radio or car radio equipped with this technology. Since the end of 2019, all radio receivers sold in France, except car radios, integrate DAB+. And from 2020, all new car radios sold in France will also include DAB+. As with the FM band, DAB+ radio reception remains completely free of charge.
Karim El Naggar, Managing Director of TDF's Audiovisual BU, comments: "I am delighted that DAB+ has arrived on the local Rennes allotment from TDF's emblematic site in Cesson-Sévigné. TDF has a strong and long-standing presence in the region in terms of innovation and technical expertise. TDF is committed to supporting its customers, the program publishers, to best meet their digital coverage needs. To do this, we are drawing on our expertise in radio broadcasting over almost 50 years to provide a complete DAB+ offering, from feed collection and headend, to signal transport via our entire existing network, and of course broadcasting."
