China starts 5G broadcast project with Bavarian technology

5G TODAY Broadcast Partner Rohde & Schwarz Delivers Technology

12.8.2019 Following the Bavarian example of the 5G TODAY project, China will start broadcasting its own 5G broadcast test network in August. The aim is to achieve the commercial use of 5G broadcasts for large-scale TV transmissions up to the 2022 Olympic Winter Games in Beijing and further national expansion by 2025. With the realization of the project with the Academy of Broadcasting Science (ABS) and China Broadcasting Network. Co. Ltd. (CBN), two public institutions of the government agency Chinese National Radio and Television Administration (NRTA) entrusted with.

The 5G TODAY project in Bavaria, funded by the Bavarian Research Foundation (BFS) and in operation since May 2019, completely convinced the NRTA delegation to also operate such an experimental field. For some time now, NRTA has been researching the next-generation mobile communications standard. The FeMBMS (Further Evolved Multimedia Broadcast Multicast Service) and the associated High Tower High Power (HTHP) concept are now regarded by NRTA as the most suitable solution. The fact that CBN received the commercial 5G license of 4.9 GHz with 50 MHz band in June 2019 makes a FeMBMS field test the logical consequence.

With the CCTV Tower, Jing Guang Center and Ming Ren Square, the Beijing test network comprises three stations which are operated in a single-frequency network (SFN) and are approximately 10 km apart. When setting up the network, both ABS and CBN relied on Rohde & Schwarz transmitters and core network components, as Rohde & Schwarz has been an important driving force behind 5G broadcasting for years. The transmitters with an output power of 1 kW will operate at a center frequency of 754 MHz with a bandwidth of 5 MHz (later 10 MHz). An SDR receiver (Software Defined Radio) developed by the Technical University of Braunschweig and a signal analyzer from Kathrein are included in the same test package. With this end-to-end implementation, ABS and CBN plan to carry out various tests, such as field strength propagation, network coverage, mobility reception, application possibilities and cooperation with the LTE-Unicast network.
