The R&S THU9evo high-power transmitter with a transmission power of 5 kW (100 kW ERP) and the specially developed antenna from German technology company Kathrein are part of the LTE Broadcast test transmission. The Rohde & Schwarz FeMBMS transmission addresses broadcast applications for video and IP data in HPHT topologies with bandwidths of 5 MHz and 10 MHz. The transmitter receives the reference and configuration data via 3GPP-conform protocols from an LTE EPC (Evolved Packet Core). The research project uses the Rohde & Schwarz broadcast service and control centre R&S BSCC that contains all necessary EPC functions. The broadcast services are provided by BR and transferred to the R&S BSCC via an R&S AVHE100 headend.

The transmitters in Ismaning and on the Wendelstein mountain form a Single Frequency Network (SFN), which is to enable mobile and portable reception in the greater Munich area as well as on the main traffic routes between Munich and Salzburg. Kathrein developed a special antenna for the transmission of diversity signals for the transmitter station in Ismaning. 12 UHF antenna fields were installed at a height of 200 meters. The project also included the installation of a 370-metre long, arm-thick HF transmission cable. Another Rohde & Schwarz high-power transmitter with 7 kW output power for 100 kW ERP is to be connected to the antenna at the end of January 2019. The test broadcasting network will then be prepared for the measurements.
