The common Wi-Fi standard’s formal technical name is IEEE 802.11. It is the IEEE family of standards for wireless local area networking; “Wi-Fi” is the familiar name for the wireless networking ecosystem, not the formal IEEE standard number.
What does IEEE 802.11 mean?
IEEE 802.11 specifies how devices communicate over a wireless local area network (WLAN). The IEEE describes it as defining MAC (medium access control) and physical-layer specifications for wireless connectivity among fixed, portable, and moving stations in a local area. In practical terms, it covers how devices use the wireless network link, rather than guaranteeing a particular internet connection or experience.
The formal title of the current consolidated standard is “Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications.” The IEEE Standards Association lists IEEE 802.11-2024 as active. Its publication date is April 28, 2025, and it incorporates amendments 1 through 7 published during 2021–2024.
Is Wi-Fi the same as IEEE 802.11?
They are closely related, but the terms do different jobs. IEEE 802.11 is the name of the standards family; Wi-Fi is the familiar ecosystem name used for wireless networking products and generations. So, if someone asks for the official technical standard name, IEEE 802.11 is the precise answer—not simply “Wi-Fi.”
#1 Best Overall
- DUAL-BAND WIFI 6 ROUTER: Wi-Fi 6(802.11ax) technology achieves faster speeds, greater capacity and reduced network congestion compared to the previous gen. All WiFi routers require a separate modem. Dual-Band WiFi routers do not support the 6 GHz band.
- AX1800: Enjoy smoother and more stable streaming, gaming, downloading with 1.8 Gbps total bandwidth (up to 1200 Mbps on 5 GHz and up to 574 Mbps on 2.4 GHz). Performance varies by conditions, distance to devices, and obstacles such as walls.
- CONNECT MORE DEVICES: Wi-Fi 6 technology communicates more data to more devices simultaneously using revolutionary OFDMA technology
- EXTENSIVE COVERAGE: Achieve the strong, reliable WiFi coverage with Archer AX1800 as it focuses signal strength to your devices far away using Beamforming technology, 4 high-gain antennas and an advanced front-end module (FEM) chipset
- OUR CYBERSECURITY COMMITMENT: TP-Link is a signatory of the U.S. Cybersecurity and Infrastructure Security Agency’s (CISA) Secure-by-Design pledge. This device is designed, built, and maintained, with advanced security as a core requirement.
The IEEE’s project description says: “This standard defines one medium access control (MAC) and several physical layer (PHY) specifications for wireless connectivity for fixed, portable, and moving stations (STAs) within a local area.” See the IEEE 802.11 working-group page.
How do Wi-Fi generation names relate to 802.11?
Familiar generation labels provide a simpler way to refer to particular 802.11 work. The IEEE’s examples include these mappings:
Rank #2
- Dual-band Wi-Fi with 5 GHz speeds up to 867 Mbps and 2.4 GHz speeds up to 300 Mbps, delivering 1200 Mbps of total bandwidth¹. Dual-band routers do not support 6 GHz. Performance varies by conditions, distance to devices, and obstacles such as walls.
- Covers up to 1,000 sq. ft. with four external antennas for stable wireless connections and optimal coverage.
- Supports IGMP Proxy/Snooping, Bridge and Tag VLAN to optimize IPTV streaming
- Access Point Mode - Supports AP Mode to transform your wired connection into wireless network, an ideal wireless router for home
- Advanced Security with WPA3 - The latest Wi-Fi security protocol, WPA3, brings new capabilities to improve cybersecurity in personal networks
| Familiar label | IEEE association | Band context |
|---|---|---|
| Wi-Fi 4 | 802.11n | The IEEE timeline says it supported 2.4 GHz and 5 GHz. |
| Wi-Fi 5 | 802.11ac | A generation mapping shown by the IEEE Technology Navigator. |
| Wi-Fi 6 | 802.11ax | A generation mapping shown by the IEEE Technology Navigator. |
| Wi-Fi 6E | 802.11ax extended into 6 GHz | 6 GHz availability depends on the country and equipment. |
These names are useful shorthand, but a label alone does not tell you every capability a particular router or device supports. For example, the 6 GHz association for Wi-Fi 6E should not be read as a promise that the band is available everywhere. The IEEE Technology Navigator provides the cited generation associations; the IEEE Wi-Fi timeline gives the Wi-Fi 4 band example.

What the 802.11 name does—and does not—tell you
IEEE 802.11 identifies the technical standards family behind wireless local networking. It does not, by itself, specify the speed you will get, the quality of your internet service, the coverage of your home, or whether every pair of devices will work together as you expect. Those outcomes depend on the actual equipment, its supported capabilities, and the network environment.
