​​On July 27, 2020, NRECA, along with the Utilities Technology Council (UTC), American Public Power Association (APPA), America Gas Association (AGA), and American Water Works Association (AWWA) filed reply comments opposing any further expansion of unlicensed operations in the 6 GHz band until real-world testing has been conducted and has proven that low power indoor (LPI) devices will not cause harmful interference and that Automatic Frequency Control (AFC) will effectively prevent standard-power access systems from causing interference to licensed microwave systems in the band.
