Which technology covers a metropolitan area and connects subscriber stations to a base station over wireless or fiber links?

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

Answer: (D)

A system that covers a metropolitan area and links subscriber stations to a base station over wireless or fiber backhaul is a Wireless Metropolitan Area Network. This type of network spans city-scale distances, larger than a building or campus but smaller than a national WAN, and is designed to serve multiple users and locations within a city by connecting them to a central base station through wireless links or fiber backhaul. This setup matches the description because it specifically aims to provide metro-area coverage and terminals connect back to a base station to access the broader network. WLAN, by contrast, is intended for local areas like a single building or campus, offering short-range connectivity. WWAN refers to wide-area wireless networks, typically covering larger regions and often associated with cellular networks, which is broader than the metro-scale focus described. DSSS is a modulation technique used in some wireless technologies, not a network type itself, so it doesn’t describe a metro-area connectivity solution.
