You know that wireless phones, and wireless routers run on 2.4 ghz. Some of that technology is also running on 5.8 ghz. I would think that the same rules apply as secondary users of the bandwidth.

I would not be surprised to see 5.8 ghz come into use for RC control. I do know one thing, I refuse to fly my $2500 planes when another flier is using the $50 radio & $10 receiver from hobby king. I just don't trust them.... YET!

I have an EE background and am a ham.
