WI-FI Alliance Certification

The Wi-Fi Alliance is a commercial alliance that owns the Wi-Fi trademark and is responsible for Wi-Fi certification and trademark licensing. Its primary purpose is to promote compatibility certification for Wi-Fi products worldwide and advance wireless local area network (IEEE 802.11 standard) technology.

Wi-Fi Alliance Certification

Ⅰ . Wi-Fi Alliance

(full name: International Wi-Fi Alliance, English: Wi-Fi Alliance, WFA for short), is a business alliance that owns the trademark of Wi-Fi.

It is responsible for Wi-Fi certification and trademark authorization, and is headquartered in Austin, Texas, USA.

Founded in 1999, the main purpose of the alliance is to promote the compatibility certification of Wi-Fi products on a global scale and to develop the wireless local area network technology of IEEE802.11 standard. Simply put, the Wi-Fi Alliance is a non-profit organization that promotes Wi-Fi technology and certifies whether Wi-Fi products meet interoperability standards. The Wi-Fi Alliance created the term "Wi-Fi" and owns Wi-Fi Fi series logo. Manufacturers can use the mark for certified products that have undergone interoperability testing.

Ⅱ . Wi-Fi Alliance testing and certification process

1. Become a Wi-Fi member (different levels have different permissions, see the figure below). If your company wants to conduct a Wi-Fi certification test for a product, you must confirm whether your company is already a member of Wi-Fi. Because only Wi-Fi members can apply for the Wi-Fi certification test.

2. After becoming a member, apply for CID and test online.

3. Conduct tests and review test reports.

4. Pass the test and get a certificate

5. There are 3 categories of members: Contributor, Small Business, Implementer, and the fees are as above.

Ⅲ . Wi-Fi Alliance certification test content

1. Interoperability

Verify the interconnection and interoperability between the test equipment and the standard equipment of different chip manufacturers on the test platform.

2. Throughput

The test case defines the user scenarios and throughput limit requirements of different working modes such as single user, multi-user, Wi-Fi 802.11a/b/g/n, and examines the throughput performance of the device under test.

3. Protocol consistency

backoff mechanism.
Encryption mode (WPA2-AES, WPA-TKIP, WEP).
Protection measures for 802.11n devices to 802.11b and g devices, and protection measures for 802.11g devices to 802.11b devices.
802.11n protocol.

4. Wi-Fi Alliance Certification Scope

It is mainly aimed at several working modes of Wi-Fi 802.11a/b/g/n/ac/ax, and usually uses 2.4G UHF or 5G SHF ISM radio frequency band products. Products including smartphones, home appliances, computers and peripherals, network infrastructure and consumer electronics can all be certified.

5. Product certification method

Initial certification: The wireless LAN products developed by the manufacturer apply to the Wi-Fi Alliance for certification to ensure that product compatibility and related performance meet the relevant standards of the Wi-Fi Alliance. Certification needs to send samples to relevant institutions (such as Shenguang Standard Technology), and the product can only be authorized for production after the test meets the requirements

Derived certification: The manufacturer‘s product is similar in Wi-Fi technology design to a previously developed authorized product (called the parent model) that has passed the Wi-Fi Alliance certification test, and can pass Wi-Fi through derived certification. Alliance certified, no need to send samples for testing. Specifically, apply for and submit the product model on the official website of the Wi-Fi Alliance, declare the similarities and differences with the parent model, and produce it after the Wi-Fi Alliance judges that it can be authorized. The above two authentication methods can obtain authorization certificates after passing the authentication of Wi-Fi Alliance. Authorized products can use related Wi-Fi technologies and Wi-Fi trademarks stipulated by the Wi-Fi Alliance.
