Wireless connection--------------------------------------------------------------------

Wireless connections provide mobile access to the Internet, allowing you to stay online anywhere the wireless signal covers.

Divided by the signal scales, wireless connection to the Internet can be built based on the following standards.

Wi-Fi	Wi-Fi networks cover a small physical area, like a home,
	office, or small group of buildings. An access point is
	necessary for the connection.

WiMAX	WiMAX networks connect several Wireless LAN systems
	to cover a metropolitan area, providing high-speed
	broadband access without the need for cables.

Mobile Broadband	The Mobile Broadband network provides Internet access
	to computers, cell phones and other devices over a large
	geographic area. Mobile networks are used for data
	transmission, and access is usually provided by a mobile
	network operator. A Mobile Broadband SIM card is
	necessary for the connection.

Note: Your computer may not support all wireless connection methods.
