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
A WLAN network mode where two or
more devices connect to each other using
WLAN directly without a WLAN access
point.
Cookies
Cookies are little pieces of information,
given by the server to you, to store
information about your visits to a web
site. When you accept cookies, the server
is able to evaluate your use of the web

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 Multi-Frequency 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 more
information on the availability of EGPRS
and data transfer speed, contact your
service provider.
122
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.
Infrastructure
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 PIN 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.
123
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 internet protocol 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 as
e-mail.
WAP
Wireless application protocol. WAP is an
international standard for wireless
communication.
WEP
Wired equivalent privacy. WEP is an
encryption method that encrypts data
before it is transmitted in WLAN.
WLAN
Wireless local area network.
WPA
Wi-Fi Protected Access. Security method
for WLAN.
WPA2
Wi-Fi Protected Access 2. Security method
for WLAN.
