FCC expands Wi-Fi into 6GHz band2020-04-23 18:32 by Daniela

The Federal Communications Commission on Thursday unanimously approved new rules to open up the 6GHz spectrum band to unlicensed use, making room on the valuable mid-band spectrum range for Wi-Fi routers and other devices. The new rules make 1,200 megahertz of spectrum available for unlicensed use - effectively increasing the amount of spectrum available for Wi-Fi by nearly a factor of five.
With more than twice as much bandwidth as the 5GHz band used by Wi-Fi devices today, the 6GHz band can accommodate up to seven 160MHz channels at once. Latency stands to be a lot lower on the 6GHz band too, because there aren't any existing, older-gen Wi-Fi devices operating in that spectrum to slow things down. That gives the 6GHz band the potential to serve as an exclusive, multilane expressway for Wi-Fi devices equipped to take advantage, all of them using Wi-Fi 6, the newest, fastest and most efficient version of Wi-Fi.
"We're expecting the first set of devices to come to market in the second half of this year," said Vijay Nagarajan, vice president of marketing for Broadcom's wireless communications and connectivity division. "You'll see a whole slew of devices, both on the infrastructure side and on the client side, and much more in a much more accelerated manner in 2021."
Meanwhile, the FCC is seeking further comment on a proposal to let very low-power devices operate across the 6 GHz band to support high data rate applications, such as high-performance, wearable, AR and VR devices.
