Radio Frequency Testing

1. Introduction to Certification

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

The Wi-Fi certificate is issued by the Wi-Fi Alliance. Wi-Fi (abbreviation for Wireless Fidelity) is the standard for interoperability of wireless local area networks. Manufacturers' products must fully meet the Wi-Fi standard and pass the Wi-Fi certification. Only then can the Wi-Fi label be placed on its products.

Only companies that become members of the Wi-Fi Alliance can conduct product certification tests and use the Wi-Fi CERTIFIED logo and related trademarks.

3. Certification category

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

2. Re-certification: The product has been certified; the product and Wi-Fi related parts have changed.

3. Modification: The product has been certified; the parts related to the product and Wi-Fi will not change.

4. Test items

1. Interoperability

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

2. Throughput

(1) 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

(1) Backoff mechanism.

(2) Encryption mode (WPA2-AES, WPA-TKIP, WEP).

(3) Protection measures for 802.11n equipment to 802.11b and g equipment, and protection measures for 802.11g equipment to 802.11b equipment.

(4) 802.11n protocol.
