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.
