As part of the Bavarian research project 5G TODAY, a 5G test field for broadcasting has been set up in the Bavarian Oberland. Under the direction of the Institute of Broadcast Technology, project partners Kathrein and Rohde & Schwarz are investigating large-scale TV transmission in the FeMBMS (Further evolved Multimedia Broadcast Multicast Service) broadcast mode in 5G. They are supported by the associated partners Telefónica Deutschland and Bayerischer Rundfunk, which operates the 5G FeMBMS transmitter network as a test field at its transmitter sites.
Two Rohde & Schwarz high-power transmitters with 100 KW ERP are being installed at the Bavarian Broadcasting Corporation transmitter sites in Munich-Ismaning and on top of Wendelstein Mountain (1828 meters altitude). Kathrein antennas are being integrated and specially optimized for cellular reception. Both test transmitters will operate in a single frequency network over channel 56/57 (750 MHz to 760 MHz). The spectrum for the test transmitters are being provided by Telefónica.
The IRT has developed an FeMBMS receiver based on software defined radio (SDR) technology. IRT is also involved in transmitter network planning and test site measurements.
The 5G TODAY research project is funded by the Bavarian Research Foundation over a period of 28 months.
What is the aim of 5G TODAY?
The insights from the project 5G TODAY will contribute greatly towards advancing 5G broadcast, supporting standardization work and promoting the development of components all the way to market launch. The goal is to enable the user to take advantage of both broadcasting and unicast transmission mechanisms on a single device – comprehensively, continuously and without further restrictions.
