Bayerischer Rundfunk, or BR for short, is Bavaria’s public service broadcaster, reaching around eight million people throughout Germany every day. With ten radio stations and two television channels, two internationally renowned symphony orchestras, a celebrated chorus and more than five thousand members of staff, we are one of Europe’s most respected broadcast institutions. BR operates broadcasting centres in Munich and Nuremberg, as well as over 20 studios and its own broadcasting networks throughout Bavaria. As the fourth largest member of ARD, BR delivers many high-quality programmes to Das Erste, ARTE, 3sat, phoenix and KiKA. Included among the highlights are feature films, series, documentaries and sports broadcasts. ARD consists of nine regional broadcasters and the Deutsche Welle.
Within 5G TODAY, BR provides the necessary broadcast infrastructure. At two locations, high power FeMBMS transmitters will be installed. The transmitters are operated in a single frequency network via channel 56 (750-758 MHz). TV-content to be transmitted is also applied by BR. The main purpose of the project is to investigate the usability of 5G for the terrestrial transmission of broadcast signals. Furthermore it is of interest for the BR which opportunities 5G offers for its content, especially video content and production.
