The Wi-Fi Alliance is a global non-profit industry association specifically created to promote Wi-Fi technology and ensure the interoperability of wireless products. It manages the "Wi-Fi CERTIFIED™" program, a testing and certification process that guarantees devices from different vendors meet specific standards for interoperability, security (e.g., WPA3), and performance. While the IEEE creates the foundational 802.11 standards, the Wi-Fi Alliance is the body that certifies products based on those standards, giving consumers confidence that certified devices will work together correctly.

B. The IETF develops and promotes internet standards (RFCs) for higher-level protocols like TCP/IP, not for certifying wireless hardware interoperability.

C. The ISO is a broad international body that develops standards for numerous industries but does not have a specific program for certifying Wi-Fi devices.

D. The IEEE is a professional organization that develops and maintains the technical 802.11 standards (the foundation for Wi-Fi), but it does not test or certify commercial products.

1. RUCKUS Certified Wireless Associate (RCWA) 100 Study Guide (2015). In the section "Wi-Fi Standards and Certifications," it states, "The Wi-Fi Alliance is a global, non-profit industry association... devoted to ensuring the interoperability of wireless LAN products." It further clarifies, "The IEEE defines the standards, but it does not test products for compliance." (Page 1-10).

2. Wi-Fi Alliance Official Website. The "Who We Are" page states: "Our work includes developing innovative technologies, standards, and programs that lead the industry forward; and our Wi-Fi CERTIFIED™ program is the global standard for ensuring Wi-Fi products provide the best user experience." This confirms their role as the certifying body.

Chapter 7, Section 7.2.1, "The 802.11 Architecture," distinguishes between the IEEE 802.11 standard and the Wi-Fi Alliance, noting the Alliance's role in certifying the interoperability of 802.11 equipment.
