Microsoft announced that they are rolling out their White Space device initiative for internet access. This uses the same unlicensed (part 15) TV channels that you must operate your unlicensed wireless microphones in. These devices are powerful with a range of up to 10 miles and will make your wireless microphones unable to operate reliably. The devices are required to access the Part 74 license database before they transmit and if your wireless microphone is registered, they cannot transmit on your licensed frequency. If your wireless microphones are operating unlicensed under Part 15 it does not show up in the licensed database and the White Space device could transmit on or near the same frequency you are operating on and your wireless microphone could experience interference. Just as the article states, if your wireless microphone is not licensed, it is operating on an unused TV channel as far as the White Space device is concerned. Folks, this is serious. The Microsoft White Space Devices along with T Mobile’s new 600 Megahertz service will rapidly make it very difficult for you to operate wireless microphones as Part 15 unlicensed devices. T Mobile has announced their new 600 Megahertz phones will be on the market for Christmas 2017. The scramble to get spectrum to operate wireless equipment, including your wireless microphones, is full speed ahead and unlicensed microphones will get whatever scraps are left.
