Introduction
Generational Wi-Fi® is a marketing program introducing a new consumer-friendly naming convention assigned
to generations of Wi-Fi, based upon major Wi-Fi technology (PHY) releases. Wi-Fi generation names provide
manufacturers, operators, and end users with an easy to understand description for both the Wi-Fi technology
contained in a device and the connection that device makes with a Wi-Fi network. The goal is to allow
consumers to easily recognize the type of Wi-Fi capability found in their devices and network connections, muchas they recognize today through cellular identification of capabilities 3G, 4G, etc.
Goals of Generational Wi-Fi:•••

Increase end user recognition of Wi-Fi technology advancements
Differentiate and easily identify Wi-Fi technology contained in devices and network connections
Increase user adoption of newer Wi-Fi technologies that deliver a better experience

Wi-Fi generations will be identified by a numerical sequence matched to major PHY advancements in the2.4 GHz and 5 GHz frequency bands – the most common Wi-Fi experience consumers encounter. The tablebelow outlines the numerical sequence.

If the most advanced technologya device supports is …
802.11ax
802.11ac802.11n

Then it shall be identified asgeneration
Wi-Fi 6
Wi-Fi 5
Wi-Fi 4Generational Wi-Fi includes several elements for use by Wi-Fi Alliance® members and non-members, as well as
elements exclusively for the use of Wi-Fi Alliance members:••••

Wi-Fi generation names
User Interface visuals
Wi-Fi Alliance certification program names
Wi-Fi Alliance certification program logo

Usage and requirements for each of the generation name elements are explained below.

Wi-Fi generation names
Consumer-friendly generation names Wi-Fi 4, Wi-Fi 5, and Wi-Fi 6 are intended to be used widely throughout
the Wi-Fi ecosystem by Wi-Fi Alliance members, non-members, industry partners, media and analysts.
Generation names shall be used in text format to refer to the corresponding Wi-Fi technology for thegeneration. Adoption of generation names Wi-Fi 4, Wi-Fi 5, and Wi-Fi 6 as industry terminology is encouraged foruse in marketing materials and promotion with consumers, media and analysts. Generations of Wi-Fi prior toWi-Fi 4 will not be assigned names.
If a company adopts Wi-Fi generation names, the following guidelines shall be followed:•••

References to 802.11ax technology shall use the generation name Wi-Fi 6References to 802.11ac technology shall use the generation name Wi-Fi 5
References to 802.11n technology shall use the generation name Wi-Fi 4© 2018 Wi-Fi Alliance. All rights reserved.

2 of 7••••Generation names do not affect previous certification program names. For previous certification
programs (e.g. Wi-Fi CERTIFIED™ ac or earlier programs), continue to use the original certification
program name.
The format of generation names is simply “Wi-Fi” followed by a whole number. Generation names shallnot contain additional text or description. Generation names shall not have versions identified. For
example,Wi-Fi 5.1, Wi-Fi Version 5.2, or Advanced Wi-Fi 5 shall not be used.
Generation names shall only be used as a text reference
Generation names shall not be incorporated into any logo design

Wi-Fi generation names shall both refer to the most advanced technology available in devices and to the actual
Wi-Fi connection devices establish with a Wi-Fi network.
If a device vendor adopts Wi-Fi generation names, then they shall:•••Identify the Wi-Fi technology contained in a device by the correct generation nameo Example: A device containing 802.11ax technology shall be referred to as Wi-Fi 6. Statements
describing this may read as “Company ABC’s Smartphone D features Wi-Fi 6 technology.” or“Company ABC’s Smartphone D contains Wi-Fi 6 technology.”
o If technology representing more than one generation exists in a device, the device shall beidentified as the most advanced technology it contains. For example, if the device contains
802.11n 2.4 GHz and 802.11ac 5 GHz technology, it shall be referred to as Wi-Fi 5.
Use generation names for product packaging, collateral, media and analyst outreachUse generation names as part of a product name, for example Company ABC Wi-Fi 6 Access Point

If OS vendors adopt generation names, then they shall:••

Identify the generation of a Wi-Fi connection between the device and a network
Example: Tablet E may be connecting to Network F through an 802.11ac connection. The device
interface may display “Wi-Fi 5” or “5” to indicate connectivity. This display shall adjust and refer to adifferent generation name as a device moves to a different Wi-Fi connection.

If service providers adopt generation names, then they shall:•••

Identify the capability of the Wi-Fi network as Wi-Fi 6 if the network has the capability to establish an
802.11ax connection. Example statement: “Provider G features Wi-Fi 6 connections.”
Identify the capability of the Wi-Fi network as Wi-Fi 5 if the network has the capability to establish an
802.11ac connection
Identify the capability of the Wi-Fi network as Wi-Fi 4 if the network has the capability to establish an
802.11n connection

User Interface visuals
The experience a user perceives with Wi-Fi is often dominated by the speed and latency of the connection adevice is making to a network. Consumers mistakenly equate the expected quality of their Wi-Fi experience witha displayed Wi-Fi signal strength indicator. In their minds, stronger signal should equate to a better userexperience. To change that perception and map user experience to Wi-Fi generations, Wi-Fi Alliance introduces
new User Interface (UI) visuals to identify Wi-Fi generations for network connections. UI visuals are intended foruse by device manufacturers and OS vendors, whether members or non-members of Wi-Fi Alliance.
If a device manufacturer or OS vendor chooses to implement Generational Wi-Fi UI visuals, then they shall:•Use the UI visual to indicate the connection that a device is making to a Wi-Fi network© 2018 Wi-Fi Alliance. All rights reserved.

3 of 7•••••Use a UI visual associated with Wi-Fi 6 to indicate a device is connecting to a network on an 802.11ax
connection
Use a UI visual associated with Wi-Fi 5 to indicate a device is connecting to a network on an 802.11ac
connection
Use a UI visual associated with Wi-Fi 4 to indicate a device is connecting to a network on an 802.11n
connection
Implement UI visuals as dynamic symbols in a field that will adjust if/when a device moves to aconnection with a different Wi-Fi generation connection, much as Wi-Fi signal strength indicators display
and adjust in many devices today. As an example, if a device is connecting to a network over an
802.11ac connection, the device UI shall display a Wi-Fi 5 visual. If the connection switches to 802.11ax,
the UI display will change to a Wi-Fi 6 visual.
Use a UI visual only on a device display screen, not as a visual indication on packaging, marketing
materials or on the device itself

Device manufacturers and OS vendors may choose to implement UI visuals through a set of icons provided by
Wi-Fi Alliance or by customizing to fit their design style as described below.

Wi-Fi Alliance provided UI visuals
Wi-Fi Alliance provides a set of UI visuals for use in device UI by OS or device vendors to identify the type of Wi-Ficonnection a device is making at a given time on a network connection. Wi-Fi Alliance UI visuals are available athttps://www.wi-fi.org/who-we-are/our-brands.

UI visuals shall only be used on a device UI to indicate a network connection status. UI visuals shall NOT be used
for product packaging or on-product production, or to identify the technology contained in a device.

Customizable UI visuals
Where possible, the use of common UI visuals provided by Wi-Fi Alliance will assist consumer recognition ofWi-Fi generations across device types. Cases may arise where standardized font or design constraints on
devices or OS require an adjustment of these visuals to conform to device-specific or OS-specific needs anddesign styles.
If customized UI visuals are developed, then these guidelines shall be followed:
••
•
•
•

OS and device vendors shall combine numerals 4, 5, and 6 with their preferred Wi-Fi indicator andfont/color selection
The numerical representation may be placed next to, above or below the Wi-Fi indicator, or used as a
background, inlay or overlay element
Gotham font shall be used where possible
A set of three custom icons shall be created for use with Wi-Fi 4, Wi-Fi 5 and Wi-Fi 6 connections
A custom icon with the numeral 6 shall be displayed when a device is connected to a network throughan 802.11ax connection© 2018 Wi-Fi Alliance. All rights reserved.

4 of 7•••A custom icon with the numeral 5 shall be displayed when a device is connected to a network throughan 802.11ac connection
A custom icon with the numeral 4 shall be displayed when a device is connected to a network throughan 802.11n connection
Custom UI visuals shall be implemented as dynamic symbols in a field that will adjust if/when a device
moves to a connection with a different Wi-Fi generation connection, much as Wi-Fi signal strength
indicators display and adjust in many devices today. As an example, if a device is connecting to anetwork over an 802.11ac connection, the device UI display a Wi-Fi 5 visual. If the connection switches to802.11ax, the UI display will change to a Wi-Fi 6 visual

Samples of how customized UI visuals may be implemented are shown below, based upon a selection of WiFi indicators found in current devices on the market.

Wi-Fi Alliance certification program names
Beginning with the Wi-Fi 6 generation, Wi-Fi Alliance certification programs for major PHY releases in the 2.4
GHz and 5 GHz frequency bands will use a Wi-Fi generation name. The certification program associated with
802.11ax, or
Wi-Fi 6 technology, will be marketed as Wi-Fi CERTIFIED 6™. Previous certification program names will not beadjusted, but will continue as Wi-Fi CERTIFIED ac, Wi-Fi CERTIFIED n, etc.
Wi-Fi Alliance members may identify that they plan to submit devices for certification testing for Wi-Fi 6. Once adevice has been tested and successfully completed certification, it may be identified as Wi-Fi CERTIFIED 6.
Only Wi-Fi Alliance member devices that have successfully completed certification may be described as
Wi-Fi CERTIFIED 6.

Wi-Fi Alliance certification program logo
Wi-Fi CERTIFIED 6 is the certification name used for the program
based upon the 802.11ax standard. A
Wi-Fi CERTIFIED 6 logo will be available for member products,
packaging and marketing materials for devices that achieve Wi-Fi
CERTIFIED 6 certification.
This logo shall not be reproduced or used in any products ormaterials until the certification program availability is announced,and it must be used in accordance with the Wi-Fi Alliance Brand
Style Guide. When Wi-Fi CERTIFIED 6 availability is announced, the© 2018 Wi-Fi Alliance. All rights reserved.
