About WLAN
Your device can detect and connect to wireless local area networks (WLAN). Using a
WLAN, you can connect your device to the internet and compatible devices that support
WLAN.
To use a WLAN connection, you need the following:
•
WLAN must be available in your location.
•
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.
•
An internet access point created 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.
You can use WLAN during a voice call or when packet data is active. You can only be
connected to one WLAN access point device at a time, but several applications can use
the same access point.
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
•
WEP, WPA/WPA2, 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
unauthorised access to your data.
When the device is in the offline profile, you can still use WLAN, if available. Remember
to comply with any applicable safety requirements when establishing and using a WLAN
connection.
Tip: To check the unique media access control (MAC) address that identifies your device,
enter *#62209526# in the home screen.

Note: Using WLAN may be restricted in some countries. For example, in France,
you are only allowed to use WLAN indoors. For more information, contact your local
authorities.
