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 site, what

you are interested in, what you want to

read, and so on.

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.

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 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 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.
