wireless+audio+project

Hello everybody,

For a project, I need to have 10 seperate wireless stereo audio channels.
They should all be able to work at the same time with a very high reliability factor.
The operating range should be at least 100m.
And they should have very good audio quality (near cd)

I am kind of new in the whole wireless area, and I would like some suggestions on where to start looking...

I have found some chips working in the 2.5 ghz range (eg: nordic semiconductor) but they are useless when you want 10 audiolinks.

Any suggestions would be highly appreciated
