On February 22, APCO filed joint comments with other public safety and critical infrastructure stakeholders to respond to the FCC’s Public Notice seeking comment on further expanding unlicensed use of the 6 GHz band. As background, last year the FCC adopted rules to permit hundreds of millions of new unlicensed devices to operate in the 6 GHz band, which is heavily used by public safety agencies across the country. The joint comments reiterated that the new rules present a significant risk of harmful interference and advised the FCC against further expanding unlicensed use.
