Using your VAIO computer
Using Wireless LAN (WLAN)
Thanks to Sony's Wireless LAN (WLAN), all your digital devices with built-in WLAN functionality communicate freely with each other
through a powerful network. A WLAN is a network in which a mobile user can connect to a local area network (LAN) through a wireless
(radio) connection. So there is no need any more to pull cables or wires through walls and ceilings.
The Sony WLAN supports all normal Ethernet activities, but with the added benefits of mobility and roaming. You can still access
information, internet/intranet and network resources, even in the middle of a meeting, or as you move from one place to another.
You can communicate without an Access Point, this means that you can communicate between a limited number of computers (ad-
hoc), or you can communicate through an Access Point, which allows you to create a full infrastructure network (infrastructure).
