this law does not say whether it is technically prevented, e.g. to be able to fly above 120 metres at all etc...you are simply not allowed to do it! As I said, maybe you need to ask your question a little more specifically about what you are interested in...general information about the EU standard (which CH will probably adopt for the most part) can be found in the link.
