Some Wireless Microphones May Soon Be Illegal to Operate

Date Posted: 8/2/2017

In 2014, the FCC adopted rules to implement a change to existing television band and repurposing some UHF television band frequencies for new wireless broadband services.
What this means is that churches and others using wireless microphones need to be aware that it will soon be illegal to use some currently legal equipment operating in specific frequencies as they may cause interference with others who now own the bandwidth and will be operating equipment in that space.
This affects equipment operating in 600 MHz frequencies – specifically the 617-652 MHz and 663-698 MHz frequencies. All wireless microphone operations in the 600 MHz service band must cease no later than 39 months after the close of the incentive auction. The 39 month window closes on July 13, 2020.  
However, some regions will need to stop operating such equipment sooner as the FCC states: “if such operations could cause harmful interference to any 600 MHz service licensee’s operations.” In some cases, 600 MHz service licensees have already begun field application testing.
Members of UMITA, An Association of United Methodist IT professionals have put together a white paper outlining the issues and include some tips and links to rebates from some microphone companies to replace your equipment with compliant models.
