Which of the following pairing of technology to its coverage area is mismatched?

The pairing of WiFi with Wireless Metropolitan Area Network (WMAN) is mismatched because WiFi typically operates as a Wireless Local Area Network (WLAN) technology. It is designed for data communication over short distances, typically within a limited area such as a home, office, or café. In contrast, a Metropolitan Area Network (MAN) serves a larger geographic area, often covering multiple buildings or locations within a city or town, and is typically implemented using different technologies better suited for that scope.

On the other hand, Bluetooth is accurately paired with Wireless Personal Area Network (WPAN), as it is used for connecting devices over very short ranges, usually within a few meters. GSM and CDMA are both mobile communication technologies correctly associated with Wireless Wide Area Network (WWAN) because they enable cellular communications over significant distances, covering extensive geographic areas.
