About WLAN
To use a wireless LAN (WLAN) connection, it must be available in the location, and
your device must be connected to the WLAN. Some WLANs are protected, and you
need an access key from the service provider to connect to them.
Note: There might be some restrictions for WLAN use in some countries. Check with
your local authorities for more information.
Features that use WLAN, or that are allowed to run in the background while using
other features, increase the demand on battery power and reduce the battery life.
Your device supports the following WLAN features:
• IEEE 802.11b/g standard
• Operation at 2.4 GHz
• Wired equivalent privacy (WEP) with keys up to 128 bits, Wi-Fi protected access
(WPA), and 802.1x authentication methods. These functions can be used only
if they are supported by the network.
Important: Always enable one of the available encryption methods to increase the
security of your wireless LAN connection. Using encryption reduces the risk of
unauthorized access to your data.
WLAN connections
To use a wireless LAN (WLAN) connection, you must create an internet access point
(IAP) for WLAN. Use the access point for applications that need to connect to the
internet.
A WLAN connection is established when you create a data connection using a WLAN
internet access point. The active WLAN connection ends when you end the data
connection.
