However, there are exceptions depending if you are a Part 74 licensed user or unlicensed user. The two key dates during the transition period were October 13, 2018, which restricted companies from buying, renting, or selling equipment that functioned in the 600 MHz band, and the end of the transition period, which is today. Both the 700 MHz and 600 MHz are sought after because wireless can propagate through walls more efficiently. The sale of the 600 MHz frequency band further limits the available frequency channels wireless audio can use to transmit sound. government agency sold off the 700 MHz spectrum ten years ago, and with billions of dollars to be potentially made, it's likely the FCC will continue to auction off more of the wireless spectrum to companies willing to pay the price. The FCC auctioning off wireless bandwidth is nothing new. Now, any operator using wireless audio in the 600 MHz spectrum, except for you a few specific frequencies, could see a fine if caught. The ten part transition phase has ended today, July 13, 2020. Doing so, shrunk the wireless spectrum for sound operators in the film and television industry in both the United States and Canada. The auction allowed telecom and cable companies to scoop up the coveted frequency range to expand its own networks.
In 2017, No Film School reported on the FCC's auction of the 600 MHz frequency band.
