Wireless Local Area Network (Wlan) - Nokia RM-49 User Manual

service). GPRS uses packet data technology where
information is sent in short bursts of data over the
mobile network. The benefit of sending data in packets
is that the network is occupied only when sending or
receiving data. As GPRS uses the network efficiently, it
allows for quick data connection set-up and fast data
transmission speeds.
You must subscribe to the GPRS service. For availability
and subscription to GPRS, contact your network
operator or service provider.
Enhanced GPRS (EGPRS) is similar to GPRS, but it enables
faster connection. For more information on the
availability of EGPRS and data transfer speed, contact
your network operator or service provider. Note that
when you have selected GPRS as a data bearer, the
device uses EGPRS instead of GPRS if this is available in
the network.
During a voice call, you cannot establish a GPRS
connection, and any existing GPRS connection is put on
hold unless the network supports dual transfer mode.
Wireless local area network
(WLAN)
There may be restrictions on using wireless LAN in some
locations. Check with your local authorities or service
provider.
Features using wireless LAN, or allowing such features
to run in the background while using other features,
increase the demand on battery power and reduce the
battery life.
This device can detect and connect to a wireless local
area network.
If you move the device to another location within the
wireless LAN and out of range of a wireless LAN access
point, the roaming functionality can automatically
connect your device to another access point that
belongs to the same network. As long as you remain
within range of access points that belong to the same
network, your device can stay connected to the
network.
Tip: A wireless LAN connection is established
when you create a data connection using a
wireless LAN Internet access point. The active
wireless LAN connection is ended when you
end the data connection.
Your device enables different types of communication
in a wireless LAN. The two operating modes are
infrastructure and ad hoc.
• The infrastructure operating mode allows two kinds
of communication: wireless devices communicate
with each other through a wireless LAN access point
or wireless devices communicate with a wired LAN
device through a wireless LAN access point. The
advantage of the infrastructure operating mode is
that you can have more control over network
connections because they pass through an access
point. A wireless device can access the services that
are available in a regular wired LAN: company
database, e-mail, the Internet, and other network
resources, for example.
• In the ad hoc operating mode you can send data to
and receive it from other devices with compatible
wireless LAN support , for example, to be printed.
