National trade associations representing the energy and water sectors (Collectively: The Edison Electric Institute, American Gas Association, American Public Power Association, American Water Works Association, National Rural Electric Cooperative Association, Nuclear Energy Institute, and the Utilities Technology Council) commissioned an engineering study to ascertain the real-world risk and implications of the FCC’s controversial proposal to allow unlicensed access to the heavily used 6 GHz spectrum band. Using the Houston metropolitan area to measure interference from both residential and outdoor Wi-Fi access points and for Wi-Fi adjacent channel emissions, the study demonstrates that deployment of unlicensed devices as currently proposed by the FCC would cause all the existing point-to-point links in the Houston MSA to experience unacceptable levels of interference.
