FCC Authorizes First Chip Using 6 GHz Band

The FCC cleared the first device authorized to use the 6 GHz band, allocated in April for Wi-Fi and other unlicensed use (see 2004230059), approving Broadcom's BCM4389 chip. “The Commission cleared the way for such advances with its landmark action earlier this year, making up to 1,200 megahertz of spectrum available for higher powered unlicensed use,” said Chairman Ajit Pai: “Today, we are starting to see the fruits of this work, and consumers will now start to benefit in a big way.” Vijay Nagarajan, Broadcom vice president-Mobile Connectivity Division, said it's a “red-letter day” for Wi-Fi. “We've shipped 100s of millions [of] Wi-Fi 6 devices,” he said: “We look to capitalize on this install-base of devices while also heralding the Wi-Fi Space Age with 6 GHz support.” The chip uses 6025-6985 MHz. “This module may only be marketed and sold to an OEM system integrator that has an agreement with the grantee and has been provided detailed instructions on installation conditions to ensure that the correct firmware is installed,” the authorization states: “Host systems must be intended for indoor use only, outdoor applications are NOT allowed.” Consumers are likely to have 6 GHz devices “in the first half of 2021,” Nagarajan emailed.
