3G
3rd generation mobile communications. A digital system for mobile communications
that aims at global use and provides increased bandwidth. 3G lets mobile device
users access a wide variety of services, including multimedia.
Ad hoc operating mode
A WLAN network mode allowing two or more devices to connect to each other using
WLAN directly, without a WLAN access point.
Cookies
Cookies are little pieces of information a server sends to you for storage of
information about your visits to a website. When you accept cookies, the server is
able to evaluate your use of the website, what you are interested in, what you want to
read, and so on.
DNS
Domain Name System. 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, 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
availability and data transfer speed, contact your service provider.
GPRS
General packet radio service. GPRS enables wireless access for cell phones to data
networks (network service). GPRS uses packet data technology that sends
information 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.
Since 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 on 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 email and
multimedia services or to connect to the Internet and browse Web pages, you must
first define Internet access points for the services.
Infrastructure operating mode
A WLAN network mode where devices are connected to WLAN using a WLAN
access point.
