The Wi-Fi Alliance administers the certification testing through independent laboratories that it has authorized to perform the certification testing. Products that satisfy the certification testing requirements may bear the "Wi-Fi CERTIFIED" (the "Certification Mark" or the "Wi-Fi CERTIFIED Logo"). In order to provide clear information concerning the capabilities of individual Wi-Fi CERTIFIED products to purchasers of those products, the Wi-Fi Alliance also prescribes the use of Standard Indicator Icons ("SII") in connection with the "Wi-Fi CERTIFIED" Certification Logo. This manual (the "Manual") describes the requirements for the use of the Certification Mark as a standalone mark and the use of the SII with the Certification Mark. The SII replace the Capabilities Label, which the Wi-Fi Alliance previously required in connection with the Certification Mark.
