Applied Environments, Wlan Application Modes

■Applied Environments

There are two application modes for this WLAN card, the “Ad-Hoc mode” and the “Infrastructure mode”. (For further explain, please refer to the “WLAN Application Modes” below) Different modes require different settings. Please check the environment first.

Infrastructure mode: Via “Access Point” (AP) to connect to the Internet. This mode further gives wireless access to Internet or data sharing under a previously wired environment.

Ad-Hoc mode: Connecting to other computer with WLAN card. This mode does not need AP to connect to each other.

■WLAN Application Modes

	Ad-Hoc mode is a Peer-to-Peer mode. Without an AP, computers can also
Ad-Hoc Mode	connect to each other by USB Wireless LAN CARD. With this mode,
	computers are able to share data or connect to the Internet if one of them
	is already connected to.
Infrastructure	Infrastructure mode including an AP, unlike Ad-Hoc mode, enabling users
Mode	to best utilizes the frequency bandwidth of the AP.
	This mode enables users to integrate wired and wireless infrastructures.
	Through APs, wireless users are able to access wired resources, for
	example: Internet, database, and printers.
Advantages	Comparing to Ad-Hoc mode, Infrastructure mode has the following
	advantages:
	Longer distance: Through AP, the wireless access distance is longer.
	Roaming: The wireless devices can move within the AP support
	area.
	Integration of wired and wireless environment.
