As many know, the FCC already eliminated the use of wireless microphones above 700MHz.
Basically we have been using wireless and IEM in between TV channels. In this new plan they will shrink the amount of space for over the air TV and sell those frequency bands in an auction to be used mainly for Broadband internet etc. People are using less over the air TV and want more, faster broadband, wireless is the cheapest infrastructure to accomplish this. So we will less space for our wireless technology. As it currently stands there will be 6Mhz bands available above and below Channel 37 (608-614MHz) that is NOT currently occupied by a TV station. ✪
