The FCC has set a date for discontinuation of 600MHz usage for all of us:
This Consumer Disclosure requirement is set forth in Sections 74.851(l) and 15.37(k) of the Commission’s rules. It is applicable to persons who manufacture, sell, lease, or offer for sale or lease, wireless microphone or video assist devices — either (a) wireless microphones or other low power auxiliary stations (“wireless microphones”) or video assist devices, authorized pursuant to Part 74, Subpart H of the Commission’s rules, or (b) unlicensed wireless microphones authorized pursuant to Section 15.236 – to the extent that these devices are capable of operating in the 600 MHz service band (617-652 MHz / 663-698 MHz). This disclosure informs consumers that wireless microphone users must cease any wireless microphone operations in the 600 MHz service band no later than July 13, 2020. In addition, in many instances they may be required to cease use of these devices earlier if their use has the potential to cause harmful interference to 600 MHz service licensees’ wireless operations in the band.
The full update can be found here.
What does this mean for all of us in the audio industry? The 600-band is gone as of July 13, 2020. And depending upon your install and usage locations, you may experience issues due to T-Mobile’s purchase (as well as other wireless providers) of a large portion of the 600-band for cell phone usage before the July 2020 date.
Don’t get caught by surprise! The change is coming!
