Re: Ummm, what? Because wireless mic manufacturers and maybe the NFL bitched (er, filed a comment) to the FCC that white spaces devices would interfere with the use of wireless mics and the white space devices had to also avoid the freqs in the 700Mhz band the mics were using (even though most of them are "illegal" users).
this gives a good overview of this particular issue

OK, but it still doesn't make sense. The WSD should avoid a frequency in use. A mic is using the same frequency as a TV channel. The WSD should avoid that frequency in either case. What's the problem? Are they saying it couldn't detect the frequency in use because two sources are transmitting on it? If so, that's THEIR problem.
That page you point to is a highly biased opinion piece whose point is that Shure is influencing the testing, with little evidence to back it up. Again the false claim is made that the mics are a much more powerful signal than the WSDs would be. Read the first comment for some debunking.

I believe he is saying the device failed to detect the wireless mics on frequency X, because they were on Frequency Y, which is TV spectrum, so the WSD didn't look there. When the device failed to detect the wireless mics on frequency X, the opponents of the WSD pointed that out as a failure in the device.
Google is saying the devices couldn't detect the mics on frequency X, because there were none there to detect! (The mics were using the TV spectrum, frequency Y.)
