Of course it doesn't need to be audio nor video. It doesn't change the fact that you used a term that has more than one meaning without providing any context in which to interpret it. If somebody misreads it, then the problem is with your prose, not with the reader.

Which word would you suggest to use instead of "multi-media" to refer to this characteristic?

[mendesgeo]

Multi-physical layer communication protocol also could be the best way to describe it in one word.

Multi platform or "multiple media" are probably better terms. Sorry, english tech idioms are hard.
