Wi-Fi Alliance renews Wi-Fi 6 with version 6E for 6GHz band

The Wi-Fi Alliance updated its wifi 6 specifications with new wifi revision 6E. This version brings the 6 GHz band to wireless networks .

With 6E, support for connections at 6GHz is possible, with the normal 6 specification capable of only 2.4GHz and 5GHz.

Wi-Fi Alliance is introducing new terminology to distinguish forthcoming Wi-Fi 6 devices that are capable of 6 GHz operation, an important portion of unlicensed spectrum that may soon be made available by regulators around the world. Wi-Fi 6E brings a common industry name for Wi-Fi users to identify devices that will offer the features and capabilities of Wi-Fi 6 – including higher performance, lower latency, and faster data rates – extended into the 6 GHz band. Wi-Fi 6E devices are expected to become available quickly following 6 GHz regulatory approvals, utilizing this additional spectrum capacity to deliver continuous Wi-Fi innovation and valuable contributions to consumers, businesses and economies.

Wi-Fi is ready to utilize 6 GHz spectrum as it becomes available around the world. Wi-Fi Alliance continues to support international advocacy efforts to make this additional spectrum available to Wi-Fi users, while also protecting existing devices in the band. Wi-Fi has been recognized as a foundational technology for the Internet of Things, a necessary complement to delivering 5G, an important tool bringing communication networks to underserved areas, and a strong contributor to global economies. 6 GHz is well suited to facilitate Wi-Fi’s continued growth in these areas due to its adjacency to 5 GHz where Wi-Fi already operates, greater availability of wider channel sizes, and accessibility to clear spectrum with less interference from legacy Wi-Fi 4 or Wi-Fi 5 devices.  

“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 capacity of 6 GHz is enormous and will be efficiently used by Wi-Fi 6 and newer versions of Wi-Fi. The U.S. is taking a big lead on the 6 GHz market, with Europe and APAC regions also exploring access to this band.”

Once 6 GHz is made available by regulators, analysts predict the first Wi-Fi devices to use the band will include Wi-Fi 6E consumer access points and smartphones, followed by enterprise-grade access points. Industrial environments are also expected to see strong adoption from Wi-Fi 6E to deliver applications including machine analytics, remote maintenance, or virtual employee training. Wi-Fi 6E will utilize 6 GHz to deliver much anticipated augmented reality and virtual reality (AR/VR) use cases for consumer, enterprise, and industrial environments.

“6 GHz will help address the growing need for Wi-Fi spectrum capacity to ensure Wi-Fi users continue to receive the same great user experience with their devices,” said Edgar Figueroa, president and CEO, Wi-Fi Alliance. “Wi-Fi Alliance is introducing Wi-Fi 6E now to ensure the industry aligns on common terminology, allowing Wi-Fi users to identify devices that support 6 GHz operation as the spectrum becomes available.”

6 GHz addresses Wi-Fi spectrum shortage by providing contiguous spectrum blocks to accommodate 14 additional 80 MHz channels and 7 additional 160 MHz channels which are needed for high-bandwidth applications that require faster data throughput such as high-definition video streaming and virtual reality. Wi-Fi 6E devices will leverage wider channels and additional capacity to deliver greater network performance and support more Wi-Fi users at once, even in very dense and congested environments. Wi-Fi Alliance is working on the development of interoperability testing for Wi-Fi 6E that will deliver benefits to Wi-Fi users once the spectrum is available.
