Wi-Fi- Certification is the process of testing products to ensure they conform to the industry standards and is interoperable with other Wi-Fi products. The certification of products is important because it provides consumers and businesses with confidence that the wireless WLAN products marked with Wi-Fi LAN will perform correctly and will interoperate with other products marked with Wi-Fi.

To get products Wi-Fi certified, a company must be a member of the Wi-Fi Alliance. The Wi-Fi Alliance uses a well defined testing program to ensure devices conform to the industry standard and can interoperate with other certified devices. More information about Wi-Fi certification can be found at Wi-Fi.org.
