Wireless LAN
Your device supports wireless local area network (WLAN).
With WLAN, you can connect your device to the internet
and compatible devices that have WLAN. For information
about using your device with other compatible Universal
Plug and Play (UPnP) devices through WLAN, see "Home
network", on page 57.
To use WLAN, it must be available in the location and your
device must be connected to the WLAN.
Some places, like France, have restrictions on the use of
WLAN. Check with your local authorities for more
information.
Features using WLAN, or allowing such features 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 a frequency of 2.4 GHz
• Wired equivalent privacy (WEP) with keys up to 128
bits, Wi-Fi protected access (WPA), and 802.1x
encryption methods. These functions can be used only
if they are supported by the network.
Wireless LAN connections
To use WLAN, you must create an internet access point
(IAP) in a WLAN. Use the access point for applications that
need to connect to the internet. See "WLAN internet
access points", on page 17.
Important: Always enable one of the available
encryption methods to increase the security of your
WLAN connection. Using encryption reduces the risk
of unauthorised access to your data.
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.
To end the connection, see "Connection manager", on
page 18.
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.
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.
