Using Your VAIO Computer
✍
In some countries, using WLAN products may be restricted by the local regulations (e.g. limited number of channels). Therefore, before activating the WLAN functionality, read the Regulations Guide carefully. Channel selection is explained further in this manual (see Wireless LAN Channel Selection (page 58)).
WLAN uses the IEEE 802.11a*/b/g standard, which specifies the used technology. The standard includes the encryption method: Wired Equivalent Privacy (WEP), which is a security protocol and WiFi Protected Access (WPA - Proposed jointly by the IEEE and
* See the online Specifications to see whether your model supports the IEEE 802.11a standard.
Wireless LAN devices using the IEEE 802.11a standard and the ones using the IEEE 802.11b or g standard cannot communicate because the frequencies are different.
IEEE 802.11b: The standard speed is 11 Mbps, or about 30 to 100 times faster than a standard dial up.
IEEE 802.11a/g: The standard speed is 54 Mbps, or about 5 times faster than a Wireless LAN device using the IEEE 802.11b standard.
