Morphology

wireless + fidelity

Although a learner who knows 'wireless' and 'fidelity' could guess a literal meaning like 'the quality or faithfulness of something wireless,' that does not clearly map onto the technical concept of a wireless local area networking standard (Wi‑Fi). 'Wireless fidelity' is a coined, marketing/technical name whose meaning (a Wi‑Fi network) is not directly derivable from the constituent senses, so learners without prior exposure are unlikely to infer the intended referent.

Etymology

The name wireless fidelity may come from the old music term high fidelity, called 'Hi-Fi', which meant very clear sound. Makers picked a similar-sounding name so wireless fidelity ('Wi-Fi') would sound like a reliable, high-quality wireless connection, and that's why it now means the system for wireless internet.
