GHz NPRM at the Oct. 23 commissioners' meeting (see 1810020050). The proposed U.S. rules are on “the right path, but a few improvements are required,” he said Tuesday. Most important is “enabling low power indoor use throughout the 6 GHz band, which is likely to be a common sharing approach throughout various regulatory regimes and enable global equipment harmonization,” Szymanski wrote. “Harmonization leads to scale, which in turn leads to higher value at lower costs.” NAB, meanwhile, raised 6 GHz concerns in a filing in docket 18-295. The band is used for electronic news gathering, including the use of portable transmitters on cameras and temporary fixed links to transmit program material back to studios, it noted. NAB is pleased the FCC plans to restrict operations to indoor use, but said that doesn’t resolve all its concerns. “Confining unlicensed operations in these bands to indoor operations does not address the potential for interference to broadcast operations that may take place indoors” at events, the group said. “Broadcast use for newsgathering operations tends to have high 'RF visibility’ because these links travel over long distances. Such links can easily travel through residential areas where unlicensed operations near windows could cause interference.”
