Wonder what this could do to wireless Mic systems....

This is just one of the many TVBDs that will fill the "white spaces". It was this use that primarily drove the reallocation of the UHF bands. This is what has been discussed for the last 5 years on these and other forums.
There are 2 "protected" TV bands in each market for use by wireless mics. These are different in each TV market, but are the first unused band below ch37, and the first unused band above ch37. These are the frequencies you should plan on using first. With proper planning you should be able to get at least 12, and most likely more, mics into these 2 bands.
Unused TV channels that are adjacent to an active TV channel are also off limits for mobile TVBDs, so should be relatively safe for wireless mic operation. Unused TV channels that are
not adjacent to an active TV channel will be open for use by TVBDs, and in the future may be unusable for that reason. For today, where there are few (no?) TVBDs operating they are probably fine.
It is becoming increasingly important that care is taken in choosing frequencies for wireless mics. There is commercial software from
PWS,
Stage Research, and
Kaltman Creations, and probably others, that helps in RF planning by identifying unused TV channels in your zip code, and calculating intermod free frequencies. There are also free versions from
Shure, and
Sennheiser.
When using more than a couple of wireless mics, it is increasingly important to take the time to find the best RF frequencies you can. There are plenty of tools available to help you do that.
