What has been lacking so far in the distribution of broadcasting content is an efficient and direct way of reaching users with live and linear content on mobile devices without additional costs for them. That is why BR together with IRT and three industry leaders launched the 5G TODAY project in 2017. The project will test how 5G broadcasting can be used to create an overlay infrastructure that can simultaneously serve millions of future 5G mobile devices. The aim is neither to burden the regular mobile networks nor to incur additional costs for citizens.
"With its expertise in mobile communication and broadcasting technology, Kathrein can contribute its know-how from both areas. These synergies are highly valuable for us when testing various services in 5G TODAY," emphasizes Anton Kathrein, CEO of the Kathrein Group. At the transmitter in Ismaning, an antenna system from Kathrein, which is designed for the distribution of broadcast signals to mobile devices, was integrated into the test field.
HPHT transmitters from Rohde & Schwarz are used for the 5G radio transmission. "With this forward-looking concept, broadcasters can enjoy the same advantages in the distribution of video content over 5G networks as they do in classic broadcasting, such as high video quality, short latency times and long range. With our high-performance transmitters, we make a decisive contribution to the operation of the field trial," said Peter Riedel, COO of Rohde & Schwarz. The two test transmitters are operated as a Single Frequency Network (SFN) in channel 56/57 (750-760 MHz).
