Novel DAB+ mobile emergency transmitter by Rohde & Schwarz

Mobile solution can be transported in a small van

Rohde & Schwarz has created a new super-compact and lightweight portable emergency DAB+ transmitter for Bayerischer Rundfunk (BR) in Munich, Germany. This new transmitter design is a variant of the company’s R&S TMV9-4 DAB+ transmitter and ensures continuity of broadcast across BR’s DAB+ radio network.

Despite having one of the most stable and reliable DAB+ transmission networks, BR’s engineers saw a need for a reliable back up transmitter in the rare emergency situations or where scheduled maintenance requires a transmitter to power down temporarily. Rohde & Schwarz’s adapted TMV9-4 DAB+ transmitter is incredibly compact (73 x 147 x 86cm) and weighs just 250 kg. Still, it provides deceptively high 3 kW output power.

BR is using the transmitter as an emergency transmitter during the extension of their DAB+ transmitter network as an important and reliable bridging option. The new transmitter is mounted in a specially designed mobile transmitter rack system with hand grips to ease lifting and wheels to assist moving to and from a vehicle. The Rohde & Schwarz unit easily fits within a small trailer pulled behind a car or small van, and can be taken to a transmitter site within minutes of an outage occurring.  

Rohde & Schwarz engineers have developed a series of optimized hardware plug-in interfaces on the transmitter, which are designed to enable ultra-fast, on-site set up and commissioning. Despite its innovative design, the new transmitter utilizes the same standard components that are found in the transmitters throughout BR’s DAB+ network so no extra spares inventory is required.
