Which network type uses mobile telecommunication cellular technology such as 2G, 3G, 4G, and 5G?

• A. Wireless Wide Area Network (WWAN)
• B. Wireless Local Area Network (WLAN)
• C. Personal Area Network (PAN)
• D. Metropolitan Area Network (MAN)

Answer: (A)

Cellular technology that covers large geographic areas defines a wireless wide area network. This type uses 2G, 3G, 4G, and 5G to provide mobile connectivity across cities and regions via licensed spectrum and cellular towers. That broad reach is the hallmark of a WWAN. In contrast, wireless local area networks stay confined to a building or campus with Wi‑Fi, personal area networks cover very short ranges around an individual (like Bluetooth), and metropolitan area networks describe city-scale infrastructure often not based on cellular mobile tech.
