Using Wireless LAN (WLAN)

 

User

 

Thanks to Sony’s Wireless LAN (WLAN), all your digital devices with built-in WLAN functionality

 

 

 

Notebook

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

 

 

anymore 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

Sony

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).

 

✍In some countries, using WLAN products may be restricted by the local regulations (e.g. individual license, limited number of channels). Therefore, before activating the WLAN functionality, carefully read the Wireless LAN Regulation flyer.

WLAN uses the IEEE 802.11b standard, which specifies the used technology. The standard includes the encryption method: Wired Equivalent Privacy (WEP), which is a security protocol. Data encryption protects the vulnerable wireless link between clients and Access Points. Besides that, there are other typical LAN security mechanisms to ensure privacy, such as: password protection, end-to-end encryption, virtual private networks, and authentication.

Wireless LAN devices using the IEEE 802.11a standard and the ones using the IEEE 802.11b standard cannot communicate because the frequencies are different.

The standard access is 11 Mbps, or about 30 to 100 times faster than a standard dial up.
