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.
