Connectivity
Your device offers several options to connect to the
internet or to another compatible device or PC.
Wi-Fi/WLAN connection
About WLAN
To use a wireless LAN (WLAN) connection, it must be
available in the location, and 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.
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) with keys up to 128
bits, Wi-Fi protected access (WPA), 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 unauthorized access to your data.
WLAN connections
To use a WLAN, you must create an internet access
point in a 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 access point. The active
WLAN connection is ended when you end the data
connection. You can also end the connection manually.
You can use a WLAN during a voice call or when a packet
data connection 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.
When the device is in the Offline profile, you can still
use a WLAN, if available. Remember to comply with any
applicable safety requirements when establishing and
using a WLAN connection.
If you move the device to another location within the
WLAN and out of range of a WLAN access point, the
roaming functionality can automatically connect your
