Read this: Small scale DAB trials

Summary: The trials showed that the small scale approach to DAB transmission is technically sound, and they helped Ofcom, the triallists, and wider industry to understand the practical requirements for successfully sustaining DAB radio transmissions using the small scale approach. The technical documents contain more in-depth information on the technical development and operational aspects of the small scale trials, as well as technical studies on potential frequency availability for small scale DAB, a technical report on DAB receiver performance that we commissioned during the project, and some summary results of a survey of radio stations on small scale DAB that we carried out while preparing this report. - stakeholders.ofcom.org.uk
