The Federal Communications Commission has regained its authority to hold spectrum auctions and could use that power to take spectrum away from Wi-Fi networks and license it to mobile carriers AT&T, Verizon, and T-Mobile. The new law also allows spectrum to be taken from the Citizens Broadband Radio Service (CBRS), which goes from 3.55 to 3.7 GHz. While other spectrum bands could be targeted too, advocates say it would be hard for the FCC to fulfill the congressional mandate without taking spectrum from Wi-Fi, CBRS, or both. The 1,200 MHz between 5.925 and 7.125 GHz was allocated to Wi-Fi in April 2020 under then-FCC Chairman Ajit Pai. Pai is now CEO of the CTIA, the major lobby group representing mobile carriers who want access to the 6 GHz band.
