Which network type can cover a region or the entire globe and often uses embedded cellular radio technologies for data transmission?

• A. WWAN
• B. WLAN
• C. WMAN
• D. FHSS

Answer: (A)

The essential idea is long-range connectivity. A Wireless Wide Area Network is designed to cover large geographic areas, from regions to the entire globe, by using cellular radio technologies. Devices have embedded cellular radios that connect to mobile networks (like 4G/5G) and can roam across countries or continents, providing data transmission over vast distances. This is why WWAN fits the description: it combines wide geographic coverage with cellular-based data transmission. In contrast, local area networks cover small areas such as homes or offices, and metropolitan area networks typically span a city. The term you might hear about a modulation technique—frequency hopping spread spectrum—describes how some wireless signals are transmitted, but it isn’t a network type itself.
