Sharing a USB mobile broadband connection lets you get multiple computers online using a single mobile broadband device. In order to share such a mobile connection, you must have one computer serve as a host, which broadcasts a wireless signal to which other computers connect to get online. Sharing the USB mobile broadband signal is facilitated by the Internet Connection Sharing utility included with Windows Vista and Windows 7, and the ad hoc networking abilities of Windows allow you to broadcast the signal for other devices to use.
