Wi-Fi Alliance stakes its claim to the 6 GHz band
The 6 GHz band is expected to be made available in unlicensed form soon and the Wi-Fi Alliance thinks it’s a good fit for Wi-Fi 6.
While wifi most commonly uses the 2.4 GHz and 5 GHz bands, it’s always keen for more. With the advent of 5G and the auction of other higher frequency bands for mobile, especially the mid 3 GHz bands, wifi has increasingly come into direct competition with cellular for bandwidth. 5G seems to have a limitless appetite for such stuff, so the Wi-Fi Alliance seems to be planting its flag early for the 6 GHz band.
Specifically this takes the form of a sub-brand called Wi-Fi 6E, which will be used to designate devices that support connectivity over that frequency. The Alliance reckons regulators will offer up this band in unlicensed form fairly soon and it will represent a rare opportunity for the wifi ecosystem to expand its spectrum portfolio.
“6 GHz will help address the growing need for wifi spectrum capacity to ensure wifi users continue to receive the same great user experience with their devices,” said Edgar Figueroa, CEO of the Wi-Fi Alliance. “Wi-Fi Alliance is introducing Wi-Fi 6E now to ensure the industry aligns on common terminology, allowing wifi users to identify devices that support 6 GHz operation as the spectrum becomes available.”
“If the regulatory landscape permits, we expect companies to move forward aggressively with products that operate in 6 GHz because they understand the tremendous value brought to their customers by this portion of unlicensed spectrum,” said Phil Solis, Research Director at IDC. “If spectrum is made available early this year, we expect momentum of products that support operation in 6 GHz to ramp very quickly.”
The Alliance expects consumer routers to be the first to use 6 GHz, but its propagation characteristics are presumably pretty rubbish so you wouldn’t want to rely on that spectrum unless you were fairly close to the router and ideally in the same room. It could be handy for mesh wifi nodes though.
