The FCC unanimously adopted a notice of proposed rulemaking today proposing to free up as much as 1,200 megahertz of spectrum in the 6 gigahertz band for unlicensed use. The spectrum under consideration in the item is in the 5.925-7.125 GHz band.
“The proposed rules are designed to allow unlicensed devices to operate in the 6 GHz band without interfering with the operation of the licensed services that will continue to use this spectrum. In those portions of the 6 GHz band that are heavily used by point-to-point microwave links [5.925-6.425 GHz and 6.525-6.875 GHz], the Commission proposes to allow unlicensed devices to operate where permitted by an automated frequency coordination system and invites comment as to whether this is necessary for devices operated only indoors,” the agency said in a news release on the item, which was adopted in ET dockets 18-295 and GN docket 17-183. “In the other portions of the band [6.425-6.525 GHz and 6.875-7.125 GHz] where licensed mobile services, such as the Broadcast Auxiliary Service and Cable Television Relay Service, operate, the unlicensed devices would be restricted to indoor operations at lower power. These proposed rules will allow a valuable spectrum resource to be more intensively used to benefit consumers while allowing the existing licensed uses of the 6 GHz band to continue uninterrupted.
The Commission last year adopted a notice of inquiry in its mid-band proceeding that included spectrum in the 3.7-4.2 GHz and 6 GHz bands (TR Daily, Aug. 3, 2017). A number of incumbents expressed concern that use of the 6 GHz band by unlicensed devices would cause interference to their operations. Some reiterated those concerns today.
“From Wi-Fi routers to connected home appliances to retro cordless phones for those of us who still have landlines, we use devices that connect via unlicensed spectrum every day. Indeed, they’ve become so popular that there is now a shortage of airwaves dedicated for their use,” FCC Chairman Ajit Pai said.
“So today, we address this problem by proposing to open up 1,200 megahertz of spectrum in the 6 GHz band for different types of unlicensed uses. And we seek to do so in a way that will protect incumbent licensed operations in the band,” he added. “This decision will help us meet the mandate set forth in RAY BAUM’S Act to make more spectrum available for unlicensed use. It is also part of our aggressive and balanced spectrum strategy: pushing more licensed and unlicensed spectrum into the commercial marketplace and including a mix of low-band, mid-band, and high-band spectrum. And with the massive amount of wireless traffic that is off-loaded to Wi-Fi, opening up this wide swath of spectrum for unlicensed use could be a big boost to our nation’s 5G future.” Continue reading →
