DRM Digital Radio Mondiale: International Acceptance through Field Test Platform in Hannover
Ampegon supports one of the worldwide leading DRM test locations with a solid state low power transmission system to enable verified measurements, tests and reports
Turgi, Switzerland, March 20, 2015. Ampegon has granted a solid state low power (500 W) transmission solution to RFmondial GmbH in Hannover, Germany. In cooperation with the Institute of Communication Technology (IKT) at the Leibniz Universität Hannover the transmitter enables technologists to continue expert measurements and demonstrations of the DRM standard on regular city environmental broadcasting conditions. A broadcast license for 26.045 MHz shortwave has been given to the Leibniz Universität Hannover.
The installation will bring DRM technology and research equipment to the campus laboratory allowing technical demonstrations for professional listeners and reception results. The use of the equipment in mobile configuration enables a testing environment for improved car radio receivers with live reception inside a city. The unlimited access and the flexible operation of the broadcast chain including all possible configurations and power levels will help to test and demonstrate DRM live broadcast and will show the technical strength of the technology. The equipment is fully remote accessible for unmanned operation.
New algorithms, coding and power improvements will be tested and verified. System linearization and coverage conditions for several operation modes are under examination. The measurements and reports are well received in international technical publications and conferences.
This DRM installation is a complete DRM service chain maintained and operated by RFmondial together with the Leibniz Universität Hannover and the support of Fraunhofer IIS. It co-exists next to a DRM transmission in the FM band at 95.2 MHz. In parallel to experiments under their own supervision, the service is offered to receiver, module or chip-set manufacturers to verify and improve their implementations under real environmental conditions.
