2.5G

The enhancement of GSM which includes technologies such as GPRS

2G

The second generation of digital mobile phone technologies including GSM, CDMA IS-95 and D-AMPS IS-136

3G

The third generation of mobile phone technologies covered by the ITU IMT-2000 family

3GPP

The 3rd Generation Partnership Project, a grouping of international standards bodies, operators and vendors with the responsibility of standardising the WCDMA based members of the IMT-2000 family

8PSK

Octantal Phase Shift Keying

Capacity

A measure of a cellular network?s ability to support simultaneous calls

FACCH

Fast Associated Control Channel; similar to the SDCCH but used in parallel for operation of the TCH. If the data rate of the SACCH is insufficient borrowing mode is used

Packet switching

A communication system wherein the information is transmitted in packets of a set size. These packets have address headers and find their way to their destination by the most efficient route through the network. Compared to circuit switching where a connection is occupied until the traffic exchange is completed, packet switching offers considerable efficiencies as connections can be used by a number of users simultaneously

Phone book

A list of personal names and numbers stored in a mobile phone?s internal memory or in the SIM card. These numbers can be called by accessing the appropriate memory and making a single key stroke

SIM

Subscriber Identity Module; A smart card containing the telephone number of the subscriber, encoded network identification details, the PIN and other user data such as the phone book. A user?s SIM card can be moved from phone to phone as it contains all the key information required to activate the phone

STK

SIM ToolKit: specified within the GSM standard, this allows operators to add additional functions to the phone menu in order to provide new services such as mobile banking or email

USIM
