Extending DAB+ coverage into tunnels: technical solutions and real-world case studies

a webinar from the WorldDAB Spectrum and Network Implementation Committee

Thursday 3 December, 10:00 to 12:00 CET

This webinar explores the technologies and solutions used to extend reliable DAB+ coverage into tunnels and other underground environments.

Through technical presentations and real-world case studies, industry experts examine cost-effective approaches to tunnel coverage, the role of emergency break-in systems in enhancing public safety, and the use of DAB+ repeater technology to provide uninterrupted reception in underground car parks.

The programme also explores wider challenges to DAB network resilience, including the impact of wind farm developments on broadcast coverage, drawing on experiences from Norway.

The webinar concludes with a Q&A session.

Peter H. Matter, born in 1962, has a long history in radio. In 1983, as the primary driving force behind one of the first seven private radio stations, he then was the youngest radio pioneer in Switzerland. He studied electrical engineering, specialising in radio-communications, and founded Sumatronic in late 1987. Since then, the entire signal chain—from the studio and transmission networks to the FM transmitters—has been part of his daily work. For about 20 years, he has also been deeply focused on DAB+. Today, Sumatronic manufactures a complete product line of DAB repeaters and various specialty products in this field.
