What is the trademarked phrase associated with Wi-Fi?

• A. IEEE 802.11
• B. WiFi Certified
• C. Wireless Fidelity
• D. 802.11a

Answer: (A)

Branding and certification marks accompany Wi‑Fi technology. While Wi‑Fi is the brand name, there is a specific trademarked phrase that indicates devices meet the Wi‑Fi Alliance’s interoperability standards: “Wi‑Fi Certified.” This mark is used on devices that pass the certification program, signaling they work together with other Wi‑Fi devices.

The other terms are different: IEEE 802.11 is the family of wireless LAN standards, not a brand or slogan; 802.11a is just one variant within that standard; and Wireless Fidelity is historically the expanded meaning behind the Wi‑Fi acronym, but it’s not a current trademark or branding mark.
