Rohde & Schwarz Exports 5G Broadcast to China

China’s Academy of Broadcasting Science (ABS) and China Broadcasting Network Co. Ltd. (CBN), two public institutions under governmental authority Chinese National Radio and Television Administration (NRTA), will cooperate and set up a 5G Broadcast field trial in Beijing.

Following the example of the 5G TODAY project in Bavaria, the Chinese trial network will go on air in August before BIRTV 2019. This trial is the first step of the long-term strategies pursued by both parties, which comprise 5G broadcast commercial deployment by 2022 Winter Olympic Games in Beijing, followed by further national expansion by 2025. Rohde & Schwarz is supplying the transmitters and core network components.

NRTA has been researching on possible next generation broadcasting for quite some time. The FeMBMS (Further evolved Multimedia Broadcast Multicast Service) and related High Tower High Power (HTHP) concept specified in 3GPP release 14 seem to be in line with their requirements. Affirming through the fact that CBN got commercial 5G license of 4.9GHz with 50MHz band in June 2019, a FeMBMS field trial is consequently a logical move to step in the new mobile world. Both ABS and CBN have decided to rely on Rohde & Schwarz transmitters and core network components to set up the network.

Already a driving force for 5G Broadcast, Rohde & Schwarz says, with this next generation concept, broadcasters can distribute content over 5G networks for different kinds of applications. The advantages, such as high video quality, short latency times and wide coverage, are expected to attract more mobile users. 

The Beijing Trial network contains three stations operating in a single-frequency-network (SFN). The stations – CCTV Tower, Jing Guang Center and Ming Ren Square – are around 10km away from each other. Transmitters from Rohde & Schwarz with 1kW output power will be working at central frequency 754MHz with 5MHz bandwidth (later on 10MHz). A software defined radio receiver developed by Technische Universitaet Braunschweig, Germany, and Kathrein signal analyser are included in the same trial package. With this end-to-end implementation, ABS and CBN plan to carry out varies of tests, such as field strength propagation, network coverage, mobility reception, application possibilities and interworking with LTE unicast network.

The 5G TODAY project in Bavaria, funded by the Bavarian Research Foundation (BFS), on-air since December 2018, convinced the NRTA delegation to make the decision for setting up its own trial project, when they visited Munich to investigate the 5G Broadcast solution in midth of April 2019. The Bavarian public broadcaster Bayerischer Rundfunk, the Institute for Broadcast Technology (IRT), Kathrein, Rohde & Schwarz and Telefónica Deutschland are cooperating in this research project to explore a broadcasting solution for the future 5G technology. Two Rohde & Schwarz high-power transmitters respectively located at Wendelstein and Ismaning Stations are transmitting both with 100kW antenna power in SFN. 

To learn more about the first 5G broadcast trial project in China, visit Rohde & Schwarz China on booth 8A11 at the Beijing International Radio, TV & Film Exhibition (BIRTV) 20-24 August 2019.
