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 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
