About WLAN
Your device can detect and connect to WLANs. 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 internet 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
● Wired equivalent privacy (WEP), Wi-Fi protected
access (WPA/WPA2), and 802.1x authentication
methods. These functions can be used only if they
are supported by the network.
