Wi-Fi

1. Certification Overview

Wi-Fi Alliance (WFA) is an industry association that owns the Wi-Fi trademark and manages Wi-Fi certification and trademark licensing.

Wi-Fi certificates are issued by Wi-Fi Alliance. Wi-Fi, short for Wireless Fidelity, serves as a wireless LAN interoperability standard. Manufacturers may label products with Wi-Fi only when they fully meet the standards and pass certification.

Only Wi-Fi Alliance member companies may apply for product certification testing and use the Wi-Fi CERTIFIED mark and related trademarks.

3. Certification Categories

1. New product certification: Wi-Fi certification is not inherited.

2. Recertification: The product is already certified, but Wi-Fi-related parts have changed.

3. Variant certification: The product is already certified, and its Wi-Fi-related parts remain unchanged.

4. Test Items

1. Interoperability

(1) Verify connectivity and interoperability between the device under test and reference equipment using chipsets from different manufacturers on the test platform.

2. Throughput

(1) Test cases define single-user and multi-user scenarios and throughput limits for modes such as Wi-Fi 802.11a/b/g/n to assess the device's throughput performance.

3. Protocol Conformance

(1) Backoff mechanism.

(2) Encryption modes: WPA2-AES, WPA-TKIP and WEP.

(3) Protection of 802.11b/g devices by 802.11n devices, and protection of 802.11b devices by 802.11g devices.

(4) 802.11n protocol.
