Explanation

GAN (Global Area Network) is specifically designed to support mobile communications across an arbitrary number of wireless LANs and satellite coverage areas, making it the only option that fits the description of a globally spanning, mobile-capable network.

• A (LAN) is a Local Area Network - it covers a single building or campus and has no mobile roaming capability across multiple sites.
• B (WAN) is a Wide Area Network - it connects geographically distant fixed networks (like the internet), but it is not specifically architected to coordinate mobile handoffs between wireless LANs and satellites.
• D (HAN) is a Home Area Network - the smallest scope of all, typically connecting devices within a single residence.

Memory tip: Think of the G in GAN as Global - it's the only network type that operates at a planetary scale and was designed to let mobile devices roam seamlessly between any wireless LAN or satellite zone anywhere on Earth.
