FCC Reallocates 6GHz Wi-Fi Band to Mobile Carriers: Threatens Next-Gen Wi-Fi Speeds & Innovation

The Federal Communications Commission (FCC) of the United States has once again regained its authority to conduct spectrum auctions and now plans to reallocate a portion of the 6GHz band—previously designated for Wi-Fi—to major mobile network operators such as AT&T, Verizon, and T-Mobile.
In April 2020, the FCC allocated the 1200MHz range between 5.925GHz and 7.125GHz exclusively for unlicensed Wi-Fi use. At the time, FCC leadership rejected requests from mobile carriers to utilize the spectrum for cellular networks, reasoning that dedicating the entire 6GHz band to Wi-Fi would significantly enhance residential internet speeds.
However, the regulatory landscape has since shifted. The FCC now intends to auction off the 6.425GHz to 7.125GHz portion of the band to telecom providers, effectively shrinking the spectrum available for Wi-Fi to just 5.925GHz through 6.425GHz. This contraction may hamper the growth and performance of next-generation Wi-Fi technologies.
Currently, Wi-Fi operates across three primary frequency bands: 2.4GHz, 5GHz, and 6GHz. The 6GHz band, crucial for Wi-Fi 6E and Wi-Fi 7, spans from 5.925GHz to 6.525GHz in practical use and supports up to 61 channels, offering ultra-high data transfer rates.
Following a congressional vote, former President Trump signed legislation authorizing the FCC to auction off part of the 6GHz spectrum. As a result, frequencies between 6.425GHz and 7.125GHz will no longer be available for Wi-Fi applications. This reduction could lead to increased congestion, slower data transmission, and diminished performance for Wi-Fi networks.
Each Wi-Fi band offers distinct advantages: 2.4GHz excels in signal penetration, 5GHz provides faster speeds with moderate coverage, and 6GHz delivers superior throughput but has limited range due to higher frequency. As such, 5GHz remains the predominant choice for most home networks.
Spectrum regulations vary by country and region. The FCC’s decision to auction part of the 6GHz band applies only within the United States and does not affect spectrum policies in other jurisdictions.
