Broadcasters are often asked why they do not make greater use of Single Frequency Networks (SFNs). After all, they are hugely more spectrum efficient, aren’t they? Indeed, SFNs do have a number of advantages over Multiple Frequency Networks (MFNs). In particular, they can improve the quality of coverage and give more flexibility to network implementation – and they have potentially higher spectrum efficiency, too. However, they are associated with a number of technical and non-technical constraints. This guide tells you why not all the advantages can be maximized at the same time.
