In case of multi-stream audio, does it affect any radio wave interference?

HI,

a design house in Japan asked us that;

1. According to Dev Zone, they understand that we can use multi-stream audio 6~8 channels against 1 host. Then, can many hosts such as some Audio DKs do 25 channels multi-stream audio?

2. In above #1, does it affect any radio wave interferences?

Please give some advices.
