DAB network resilience: timing and synchronisation
a webinar from the WorldDAB Spectrum and Network Implementation Committee
The resilience of Digital Audio Broadcasting (DAB) networks is emerging as a critical issue as this technology progressively replaces legacy analogue transmission systems, in particular FM broadcasting. Single Frequency Networks (SFNs) based on DAB offer significant advantages, including wide-area coverage, reduced energy consumption, lower CO₂ emissions, and substantial decreases in transmission costs. These benefits, however, are contingent upon stringent synchronisation of the modulated signals to prevent unintended self-interference.
The time references required for transmitter synchronisation are susceptible to degradation due to drift, intentional jamming, unintentional interference, or other impairments. Consequently, both network operators and equipment manufacturers are implementing diverse mitigation strategies to enhance robustness, reduce susceptibility to disturbances, and ensure high availability of DAB networks, even in scenarios where conventional time reference sources cannot be considered fully reliable. Although mature DAB networks, especially larger SFN network, provide an inherent network resilience thanks to overlapping coverages.

Session moderator
Hanns Wolter
Technical Director, DAB Italia and Chair, WorldDAB Spectrum and Network Implementation Committee
Hanns has been working in the DAB world since 2000 as a Product Manager and has, in these years worked on all issues regarding DAB, at both a national and international level, including the introduction of DAB+ in 2007. He is involved in network planning and spectrum issues and also works closely with hardware manufacturers for the deployment of a comprehensive DAB environment. Currently, he is responsible for the planning and management of the ongoing roll-out of DAB Italia’s network and all issues related to the creation, distribution and transmission of the multiplex.
