3G
3rd generation mobile
communications. A digital system for
mobile communications which aims at
global use and provides increased
bandwidth. 3G lets a mobile device
user access a wide variety of services,
such as multimedia.
Ad-hoc
operating
mode

more devices connect to each other
using WLAN directly without a WLAN
access point.

DNS
Domain name service. An internet
service that translates domain names
such as www.nokia.com into IP
addresses such as 192.100.124.195.
Domain names are easier to remember
but this translation is needed because
the internet is based on IP addresses.
DTMF tones Dual-tone multifrequency tones. The
DTMF system is used by touch-tone
telephones. DTMF assigns a specific
frequency, or tone, to each key so that
it can easily be identified by a
microprocessor. DTMF tones allow you
to communicate with voice mailboxes,
computerised telephony systems, and
so on.
EAP
Extensible authentication protocol.
EAP plug-ins are used in wireless
networks to authenticate wireless
devices and authentication servers.
EGPRS
Enhanced GPRS. EGPRS is similar to
GPRS, but it enables faster connection.
For availability and data transfer
speed, contact your service provider.

GPRS
General packet radio service. GPRS
enables wireless access for mobile
phones to data networks (network
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 setup and fast data
transmission speeds.
You must subscribe to the GPRS service.
For availability and subscription to
GPRS, contact your service provider.
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.
GPS
Global positioning system. GPS is a
worldwide radio navigation system.
HSDPA
High-speed downlink packet access.
HSDPA brings high-speed data delivery
to 3G terminals, ensuring that users
requiring effective multimedia
capabilities benefit from data rates
previously unavailable because of
limitations in the radio access network.
HTTP
Hypertext transfer protocol. A
document transfer protocol used in the
web.
HTTPS
HTTP over a secure connection.
IMAP4
Internet mail access protocol, version
4. A protocol used for accessing your
remote mailbox.
Internet
access point
An access point is where your device
connects to a network. To use e-mail
and multimedia services or to connect
to the internet and browse web pages,
you must first define internet access
points for these services.
Infrastructur
e operating
mode
A WLAN network mode where devices
are connected to WLAN using a WLAN
access point.
PIN
Personal identity number. The PIN
code protects your device from
unauthorised use. The PIN code is
supplied with the SIM card. If the PIN
code request is selected, the code is
required each time the device is
switched on. The PIN code must be 4 to
8 digits long.
PIN2
The PIN2 code is supplied with some
SIM cards. The PIN2 code is required to
access certain functions supported by
the SIM card. The length of the PIN2
code is 4 to 8 digits.

POP3
Post office protocol, version 3. A
common mail protocol that can be
used for accessing your remote
mailbox.
PUK and
PUK2
Personal Unblocking Key. PUK and PUK2
codes are required to change a blocked
PIN code or PIN2 code, respectively.
The length of the code is 8 digits.
SIP
Session Initiation Protocol. SIP is used
for creating, modifying, and
terminating certain types of
communication sessions with one or
more participants.
SSID
Service set identifier. SSID is the name
that identifies the specific WLAN.
Streaming
Streaming audio and video files means
playing them directly from the web
without downloading them first to
your device.
UMTS
Universal Mobile Telecommunications
System. UMTS is a 3G mobile
communication system. Besides voice
and data, UMTS enables audio and
video delivery to wireless devices.
When you use your device in GSM and
UMTS networks, multiple data
connections can be active at the same
time, and access points can share a
data connection. In the UMTS network,
data connections remain active during
voice calls. You can, for example,
browse the web faster than previously
possible while simultaneously
speaking on the phone.
UPIN
PIN code used in UMTS network.
UPUK
UPIN Unblocking Key. UPUK code is
required to change a blocked UPIN
code or PIN2 code. The length of the
code is 8 digits.
USIM
SIM card used in UMTS network.
USSD
command
A service request, such as request to
activate an application or configure
various settings remotely, that you can
send to your operator or service
provider with your device.
VoIP
Voice over IP technology. VoIP is a set
of protocols that facilitate phone calls
over an IP network, such as the
internet.
VPN
Virtual private network. VPN creates a
secure connection to compatible
corporate intranet and services, such
