Disagreements Abound on 6 GHz Client-to-Client Devices

the need to make the band even more useful by facilitating the applications that client-to-client communications will support,” said the Wi-Fi Alliance. Many opponents seek "to re-litigate the Commission’s sound decision to permit unlicensed device access to the 6 GHz band,” the alliance said. C2C will become the standard worldwide, said Apple, Broadcom, Commscope, Facebook, Google, Hewlett Packard Enterprise, Intel, Microsoft and Qualcomm. “Peer-to-peer use cases like those that would be facilitated … are standard in other bands for many consumer electronic devices in the United States,” the companies said: “They include onboarding smart home equipment using smartphones, sharing streaming video from one device to another, and sharing files among users or devices quickly and efficiently.” Low-power indoor C2C would “improve the performance of current" uses and enable new ones, the Dynamic Spectrum Alliance said. Comments “overwhelmingly oppose allowing client-to-client communications, and the proponents have failed to provide sufficient technical information to show that such operations would not cause harmful interference to licensed microwave systems,” said utility and public safety groups, led by APCO, the National Public Safety Telecommunications Council, Edison Electric Institute and Utilities Technology Council. C2C would “significantly increase the interference potential to licensed microwave systems,” they said. CTIA urged caution, noting that, working with Southern Co., it did some of the only 6 GHz interference testing. Results “provide prima facie evidence that even devices operating in compliance with the existing rules will cause harmful interference to incumbent users,” the group said. The Alliance for Automotive Innovation said the proposal poses a risk to vehicle-to-everything uses of the band and could also affect the 5.9 GHz band.
