Wi-Fi 6E Standard and Channels – 802.11ax Operation in the 6 GHz Band. LitePoint’s Eve Danel has developed this three-part blog series on Wi-Fi 6E and testing challenges
Wi-Fi 6E Standard and Channels – 802.11ax Operation in the 6 GHz Band. In my previous blog post, I explored the FCC’s decision to open the 6 GHz band for Wi-Fi 6E standard operation, as well as the rules the FCC put in place to protect incumbent users in that space
Two main groups are responsible for shaping Wi-Fi’s evolution. The IEEE 802.11 defines the technical specifications of the wireless LAN standard
Previous generations of Wi-Fi (going back about 20 years) focused on increasing data rates and speed. Wi-Fi 6 (also known as 802.11ax) is the new generation of Wi-Fi technology with a new focus on efficiency and performance
Wi-Fi 6 handles client density more efficiently through a new channel-sharing capability that promises true multi-user communications on both the downlink and uplink. Wi-Fi 6 also uses a new client power-saving mechanism that schedules wake-times to improve client battery life.
802.11b, the most commonly used standard at the time, had very low speeds — only up to 11 Mbps (much lower than most Ethernet wired networks — but there were no Wi-Fi mobile devices and very few laptops, so 11 Mbps was fast enough. By 2003, Wi-Fi-enabled mobile devices were introduced in the market, and portable laptops became common for business and personal use
802.11ac, also known as Gigabit Wi-Fi, is a specification in the IEEE 802.11 family applicable to WLANs (wireless local area networks). 802.11ac represents an extension or update of the legacy 802.11a standard
802.11ac is also referred to as Wi-Fi 5, using the nomenclature derived by the Wi-Fi Alliance. Although still considered current to a certain degree, 802.11ac is being displaced by the latest standard, 802.11ax, also known as Wi-Fi 6.
These devices are generally dual band, but the 2.4 GHz frequency side is still 802.11n, because .11ac is 5 GHz-specific.. As with all 802.11 standards, 802.11ac is half-duplex, shared medium radio technology that works best when employed in wireless networking environments designed by qualified professionals.
Wi-Fi 6, also known as 802.11ax, is the latest generation and standard for wireless networking that replaces the 802.11ac, or Wi-Fi 5, standard. Prior to the release of Wi-Fi 6, Wi-Fi standards were identified by version numbers ranging from 802.11b to 802.11ac.
Its performance specifics cover a range of mandatory and optional features as specified in the body of the written standard by IEEE. As with any latest Wi-Fi standard, Wi-Fi 6 is potentially better than its predecessors because of modulation and signal processing techniques that promise a more extensive network experience in high-density environments.
This is new and different, and when 6 GHz is in play, it’s referred to as Wi-Fi 6E. As with earlier standards, Wi-Fi 6 provides the same basic functionality — network access via radio technology — but with potential improvements in capacity, coverage and performance
WiFi 6(802.11ax) is designed to improve speed, increase efficiency and reduce congestion in heavy bandwidth usage scenarios. WiFi 6 is the next generation standard in WiFi technology
WiFi 6 was originally built in response to the growing number of devices in the world. If you own a VR device, multiple smart home devices, or simply have a large number of devices in your household, then a WiFi 6 router might just be the best WiFi router for you
WiFi 6 uses both 1024-QAM to provide a signal packed with more data (giving you more efficiency) and a 160 MHz Channel to provide a wider channel to make your WiFi faster. Experience stutter-free VR or enjoy stunningly vivid 4K and even 8K streaming.

IEEE 802.11 is the standard that specifies connectivity for wireless networks. IEEE 802.11, or Wi-Fi, refers to the collective group of standards—802.11a, 802.11b, 802.11g, and 802.11n
■ 802.11a: Devices conforming to the 802.11a standard allow WLANs to achieve data rates as high as 54 Mbps. IEEE 802.11a devices operate in the 5-GHz radio frequency range and within a maximum range of 150 feet (45.7 m).
These devices operate within a maximum range of 300 feet (91 m).. ■ 802.11g: IEEE 802.11g provides the same theoretical maximum speed as 802.11a, which is 54 Mbps, but operates in the same 2.4-GHz spectrum as 802.11b
IEEE 802.11 is part of the IEEE 802 set of local area network (LAN) technical standards, and specifies the set of media access control (MAC) and physical layer (PHY) protocols for implementing wireless local area network (WLAN) computer communication. The standard and amendments provide the basis for wireless network products using the Wi-Fi brand and are the world’s most widely used wireless computer networking standards
IEEE 802.11 is also a basis for vehicle-based communication networks with IEEE 802.11p.. The standards are created and maintained by the Institute of Electrical and Electronics Engineers (IEEE) LAN/MAN Standards Committee (IEEE 802)
While each amendment is officially revoked when it is incorporated in the latest version of the standard, the corporate world tends to market to the revisions because they concisely denote the capabilities of their products. As a result, in the marketplace, each revision tends to become its own standard.
The term Wi-Fi is synonymous with wireless LANs, despite the fact it’s a specific trademark owned by the Wi-Fi Alliance, a group dedicated to certifying that products meet the IEEE’s wireless standards.. In the IEEE’s naming convention, all standards that specify protocols for implementing wireless LANs fall under the 802.11umbrella
Thanks to the widespread acceptance of wireless LANs, new standards continue to be developed at a rapid pace, creating a confusing alphabet soup.. In an effort to help the general public understand the standards a bit better, the Wi-Fi Alliance in 2018 began translating the technical names of standards into an easy-to-remember numerical system (Wi-Fi 5, Wi-Fi 6) that mirrors the way that cellular technologies are named (3G, 4G, 5G).
