Lauraent Roul, of ENENSYS, is from Rennes (where COFDM was ‘invented’ at the CCETT, but by whom? ). By 2008, DVB-T is used in 35 countries. Every year 2-3 new services start. It is a great success story.
DVB-T2 is designed to make SFNs, one of the most useful features, even easier than with DVB-T. SFNs have obvious advantages in spectrum efficiency and transmitter power reduction. In an SFN network, transmitters all use the same broadcast frequency, and they are ’synchronised’ by a common time signal received from GPS. There are approaches for Regional SFNs and national SFNs.
SFNs are a great feature for national broadcasting, though making regional SFNs can be tricky. DVB-T2 brings the use of SFNs on an important step.
Comment: So, I find myself asking if France should wait for DVB-T2. What do you think?

SFN???MFN???
is it the question to reply if it is necessary to put away DVB-T and go to DVB-T2. Let’s talk about something else
