Glossary
Access controller
Physical device that manages permission and restrictions for logging onto a
computer or network.
Ad hoc
One of the two WLAN operating modes that can be selected when using the Nokia
D211. With this configuration option, users can set up a wireless local area
network where wireless stations can send and receive data directly with each
other without WLAN access points. This type of network is sometimes called a
peer-to-peer network.
Barring password
The barring password is a 4-digit code needed to change call barrings. The
password is not located in your radio card or SIM card, but in the network. You
obtain the password from your service provider or network operator when you
subscribe to the call barring service.
Dual-band functionality
Dual-band functionality provides seamless roaming between networks during a
call within the same network operator. In practice, this means that you are less
likely to get “Network busy” messages. When you are abroad, dual-band
functionality gives more roaming possibilities, depending on your network
operator's roaming agreement.
GPRS
General Packet Radio Service. GPRS is a technology that enables sending and
receiving data over a mobile network. GPRS as such is a data bearer that enables
wireless access to data networks like the Internet. The applications that use GPRS
are SMS messaging and the GPRS dial-up (for example, Internet and e-mail).
GPRS access point
Interface between a GPRS network and external packet data networks, such as
the Internet.
GSM
GSM (Global System for Mobile Communications) is a digital telecommunications
system used widely in Europe, Asia and the Pacific.
Home network
Your home network is the network run by the operator that issued your SIM card.

HSCSD
High Speed Circuit Switched Data. HSCSD technology enables a data transmission
speed of up to 43.2 kilobits per second. HSCSD technology is based on the use of
multiple timeslots at the same time. The transmission speed in a single timeslot is
9.6 or 14.4 kilobits per second.
Infrastructure
One of the two WLAN operating modes that can be selected when using the Nokia
D211. With this configuration option users can set up a wireless local area
network where wireless stations communicate with wired and wireless stations
through a WLAN access point.
Network operator
A network operator maintains a cellular telecommunications network in a specific
area, often in a particular country. Several network operators may have
overlapping networks.
Network operators offer a variety of network services, including GSM data
services such as the Short Message Service (SMS), both to individual subscribers
and service providers. Not all network operators provide exactly the same services.
Network services
Special services provided by network operators and service providers. These
services must be subscribed to, and typically include the Short Message Service
(SMS), data service and fax service.
Picture message
Text message that contains pictures. Each picture message is made up of several
text messages. This function can be used only if it is supported by your network
operator or service provider. Only devices that offer the picture message feature
can receive and display pictures.
PIN code
Personal Identification Number code. PIN code (4 to 8 digits) is an access code for
protecting a SIM card against unauthorised use.
Profile
A profile is a group of network-specific and Windows networking settings. Profiles
enable easy transfer from one network to another without having to remember all
the different settings.
PUK code
PIN Unblocking Key code. PUK is a 8-digit code supplied with the SIM card. The
code is needed when you want to change a blocked PIN code. You cannot

change the PUK code. If you lose the code, contact your service provider or
network operator.
Security code
The security code is supplied with the radio card. It protects your radio card
against unauthorised use. Keep the code secret and in a safe place, separate from
the radio card. If you key in an incorrect security code five times in succession, the
radio card will not accept the correct code for the next five minutes.
Service provider
A company that offers telecommunications services, such as network services. A
service provider may be a network operator or a separate company.
Short message
See “Text message”.
SIM card
Subscriber Identity Module card. A small plastic card with an embedded
integrated circuit. The SIM card contains all the information the cellular network
needs to identify the network user. The SIM card also contains security-related
information.
SMS
Short Message Service. SMS is a network service provided by network operators or
service providers. It enables sending and receiving short text messages over the
digital cellular network. The standard length of a text message is 160 characters.
Text message
Short message that is sent over the digital cellular network. The standard length of
a text message is 160 characters.
WEP
Wired Equivalent Privacy. A security feature using the RC4 algorithm that
performs wireless data encryption. The WEP algorithm uses up to 152-bit keys.
Wireless station
Any computing device with a PC card slot, into which the radio card can be
inserted in order to send and receive data.
WLAN
Wireless Local Area Network. A local area network in which radio links are used to
connect devices instead of physical cables.
WLAN access point
Physical device that connects wired and wireless networks together.
