News: Wireless Microphones lose out to Digital TV in USA
As part of the Digital TV switchover, to be completed in the USA on February 17th 2009, the 698 - 806 MHz spectrum currently allocated to TV broadcasters will be re-allocated to public safety as well as commercial wireless services.
In preparation for this change, FCC is no longer accepting applications for wireless microphones and other low power users of the spectrum. Previously the band was licensed to broadcasters and used for such applications as wireless microphones, cue controllers and wireless signals for camera synchronisation. A complete ban is now imposed on manufacture, import, sale or shipment of devices that operate in these frequencies. Any current license holders will have their license modified such that operation after the digital switchover will be prohibited. Operation in the remainder of the part 74H bands will continue on a secondary basis, however any manufacturers of this equipment will need to limit the devices to frequencies outside of the 698 - 806 MHz band and new authorisations will need to show compliance at the band edges if they operate in the spectrum below this band (614 - 698 MHz).
