Michael O'Rielly, one of the commissioners of the FCC (Federal Communications Commission, the US regulatory agency) has proposed that the agency initiate a procedure to open the 6 GHz band for use in Wi-Fi, after which a study commissioned by the big

Technological firms have shown that their coexistence with current services is possible.

In a meeting with the commissioners of the FCC, RFK Engineering presented the results of a study on possible interference commissioned by Apple, Facebook, Google, Qualcomm and other companies. The resulting report states that Wi-Fi in the 6 GHz band would not cause harmful interference to existing services, as long as Wi-Fi networks use the usual interference mitigation techniques and respect standards similar to those applied. in the Wi-Fi band of 5 GHz.

O'Rielly has affirmed on Twitter that this study solves many of the questions about technical interference. While acknowledging that we will have to continue investigating before issuing an opinion, he adds that the question "should lead to a proposed FCC regulation next summer."

The support of the industry

Currently, the United States uses spectrum in the 2.4 GHz and 5 GHz bands for Wi-Fi, while the 6 GHz band is reserved primarily for fixed-satellite service and fixed microwave connection.

In response to an FCC query that looked at a flexible use of the spectrum between 3.7 GHz and 24 GHz, a coalition of technology companies argued in October that the 6 GHz band should also be open to Wi-Fi, and said it was missing Spectrum not subject to license. Apple, Broadcom, Cisco, Facebook, Google, Intel, Microsoft, Qualcomm, Sony and others committed to producing 6 GHz-enabled devices "in a reasonable period of time" if the FCC opens that band.

They wrote that "spectrum not subject to licensing eliminates the barriers that hinder entry, expands consumer connectivity and allows a greater number of companies to take advantage of new business processes, thereby promoting innovation and investment in all the economy. If you open the 6 GHz band for use without a license, the Commission will facilitate such progress. "
