Rohde & Schwarz UHF transmitter debuts with native 5G Broadcast support

The launch of the R&S TM1 addresses the immediate need for broadcast operators to bridge the gap between legacy terrestrial delivery and mobile-centric standards. By offering a renewal path for TMU9 units, Rohde & Schwarz reduces the capital expenditure barrier for transitioning to ATSC 3.0 and 5G Broadcast. This move signals a shift toward more flexible, software-defined broadcast hardware that can support interactive formats and mobile TV without requiring massive physical site overhauls. As spectrum efficiency becomes more critical, the industry should watch for adoption rates of the renewal option as a proxy for how quickly terrestrial broadcasters are committing to 5G-integrated services.

Rohde & Schwarz faces intensifying competition in the broadcast transmitter market as operators accelerate migration toward next-generation standards. In early 2025, GatesAir announced its FlexAir X liquid-cooled UHF transmitter platform targeting high-power DVB-T2 and ATSC 3.0 deployments, positioning it as a direct competitor to air-cooled alternatives in the 1 kW to 10 kW range. Meanwhile, Screen Service launched its NextGen transmitter line at NAB Show 2025 with integrated ATSC 3.0 exciter support, signaling that European manufacturers are also racing to capture broadcaster upgrade budgets. The R&S TM1's air-cooled design and TMU9 renewal path differentiate it by reducing site infrastructure costs, a factor that matters particularly for mid-power operators in emerging markets.

On the regulatory and standards side, 5G Broadcast is gaining formal traction across Europe. The European Broadcasting Union published a technical report in March 2025 recommending 5G Broadcast as a complement to DVB-T2 for mobile and indoor reception, providing institutional backing for transmitters with native 5G Broadcast support. In Germany, the Federal Network Agency allocated spectrum in the 470-694 MHz band for 5G Broadcast trials through 2027, creating a near-term deployment window for hardware like the TM1. Rohde & Schwarz has been an active participant in these trials, and the TM1's native 5G Broadcast capability positions it to serve operators who need to comply with evolving spectrum mandates without separate exciter hardware.

Technical performance data from independent testing supports the efficiency claims around air-cooled transmitter designs. A 2025 study by the Fraunhofer Institute measured energy consumption reductions of up to 30% when comparing modern air-cooled UHF transmitters against legacy liquid-cooled units at equivalent power levels, validating the operational cost argument Rohde & Schwarz makes for the TM1. Additionally, Rohde & Schwarz reported in its 2025 annual results that broadcast and media segment revenue grew 12% year over year, driven partly by transmitter modernization demand in Asia-Pacific and Latin America. That growth trajectory suggests the TM1 launch targets a market with proven purchasing momentum rather than speculative demand.
