Nokia XPRESSMUSIC 5800 - Manual (Page 69)

A roaming agreement is an agreement between two or
more service providers to enable the users of one service
provider to use the services of other service providers.
● Operator selection — Select Automatic to set the device
to search for and select one of the available networks, or
Manual to manually select the network from a list. If the
connection to the manually selected network is lost, the
device sounds an error tone and asks you to reselect a
network. The selected network must have a roaming
agreement with your home network.
● Cell info display — Set the device to indicate when it is
used in a cellular network based on microcellular network
(MCN) technology and to activate cell info reception.
Wireless LAN
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 have WLAN
support.
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.
Some places, like France, have restrictions on the use of
wireless LAN. Check with your local authorities for more
information.
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
unauthorised access to your data.
WLAN connections
To use a wireless LAN (WLAN) connection, you must create an
internet access point (IAP) 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.
