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

The pairing of Bluetooth with Wireless Metropolitan Area Network (WMAN) is considered mismatched. Bluetooth technology is designed for short-range communications, typically within a space of about 10 meters. It is commonly used for connecting devices like headphones, keyboards, and smartphones within a local area.

In contrast, a Wireless Metropolitan Area Network (WMAN) provides wireless connectivity over a larger geographical area, usually within a city or a larger urban environment. Technologies that fall under the WMAN category often operate at higher ranges and speeds to support broader coverage and larger networks, such as WiMAX.

This distinction clarifies why Bluetooth does not fit within the WMAN category, as it fundamentally serves a different purpose and range compared to technologies designed for larger network infrastructures. Other pairings mentioned, such as WiFi with Wireless Local Area Network (WLAN) and CDMA with Wireless Wide Area Network (WWAN), accurately represent their respective coverage areas and technology classifications.
