Wireless Code Division Multiple Access - A mobile telecommunications protocol that utilizes the direct sequence Code Division Multiple Access signal method in order to achieve faster transmission rates and support more users.
Wireless Fidelity - Popular term for technologies based on the IEEE standards from the 802.11 working group on wireless local area networks (WLAN), though strictly defined as a certification mark of equipment conformity and inoperability, based on that family of standards.
Worldwide Interoperability Access - Popular term for technologies based on the IEEE standards from the 802.16 working group (though like Wi-Fi strictly created as a certification mark of equipment conformity and interoperability based on those standards). Potential use includes enabling the delivery of wireless broadband access over the last mile as an alternative to wired delivery (e.g. cable and DSL). WiMAX has much greater range than Wi-Fi and uses licensed spectrum. The two are widely viewed as complimentary technologies.
