If you have a ham license, then you can use 2.4gHz for data transmission,
but then you are restricted in transmission mode, encryption and data
content.

And wireless channels, as well. Some of the channels are outside the U.S.
ham bands. Since this is an amateur radio newsgroup, I made the (possibly
rash) assumption that OP was aware of these limitations. For amateurs in
the U.S., the main issue is encryption. Few of us can afford to get
anywhere near the power limits at these frequencies!
