The FCC Incentive Auction is entering
Stage 4:
- Re-purposed spectrum will be above 614 MHz (maybe higher depending on the final auction outcome). UHF systems will be able to operate as they have been, under traditional FCC regulations.
- Looking at the bigger picture, Stage 4 will take an additional 24 MHz (four TV channels) off the auction block, a significant reduction compared to previous stages. That means all UHF wireless mic and monitor systems can continue to legally tune to those channels and operate on those deemed "white space" (not used for local over-the-air TV broadcast).
As illustrated in this graphic from the FCC, re-purposed spectrum (blue and grey blocks) will not extend below TV
channel 37. Lower channels, including 14-20 that are not pictured, will remain available to mics:

This leaves the majority of the
UHF TV band unchanged. This is important for wireless
microphone operators because these frequencies have very favorable characteristics. They travel through walls, achieve extended range from low transmitter
power, use compact antennas,
etc. That is why one of our prime messages to the FCC has been that
UHF must remain part of the spectrum portfolio available to wireless microphones, especially for hyper-critical applications.
Of course, our industry would prefer that the entire 600 MHz band remain available to mics. However, the continued availability of lower
UHF, together with the access we recently gained in several alternate frequency ranges, ensures that the future includes plenty of wireless
microphone systems.
