Glossary
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
In a wireless LAN, the ad hoc operating mode allows you to send and receive data from other
devices with compatible wireless LAN support. These functions may require an additional
third party application to work. No wireless LAN access point is required. Simply make the
necessary configurations and start communicating. Ad hoc networking is easy to set up, but
communication is limited to devices that are within range and support compatible wireless
LAN technology.
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 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, computerized
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.
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 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.
PIN
Personal identity number. The PIN code protects your device from unauthorized 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.
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 wireless LAN.
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.
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. 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.
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.
WPA
Wi-Fi Protected Access. Security method for WLAN.
WPA2
Wi-Fi Protected Access 2. Security method for WLAN.
