What type of network allows users to move around the coverage area in line of sight while staying connected?

The correct answer is a Wireless Local Area Network (WLAN). A WLAN enables devices to connect to a network wirelessly within a localized area, such as homes, schools, or offices. This type of network allows users to maintain connectivity while moving around within the coverage range, as long as they remain in line of sight of the wireless access points. The flexibility and mobility offered by WLANs make them ideal for environments where device mobility is essential.

Other options have their specific characteristics: a Wireless Personal Area Network (WPAN) typically covers a much smaller area, such as the space around an individual, and is usually limited in range. A Virtual Private Network (VPN) is not a type of local wireless network but rather a method of securing internet connections. Lastly, a Local Area Network (LAN) often uses wired connections and does not inherently provide the mobility features associated with wireless setups. Thus, the WLAN is the best fit for the scenario described.
