Duplex/Full Duplex - Simultaneous two-way transmission, such as experienced in a phone conversation. In contrast, many speakerphones are half-duplex and will transmit in only one direction - from the loudest noise - at a time.
EDGE - (Enhanced Data Rates for Global Evolution) or EGRPS is an advanced method of transmitting data over a mobile phone network. This is basically an up-rated version of GPRS capable of both voice and 3G data rates up to 384 Kbps. Although a number of handsets will support this option, at the moment UK networks are concentrating on 3G technology and do not support Edge.
EFR - (Enhanced Full Rate). A system that, when implemented by both the phone and network operator, is designed to improve voice quality.
An enhanced version of 'Standard full rate codec' currently supported by all phones. It is a new dictionary of sounds that produces a better speech quality without transmitting more data over the mobile phone network Fax Fax-enabled phones can receive, store and download fax messages.
Email - The electronic transfer and storage of written messages.
Face Plate - A cover that fits around the pushbuttons of a phone. Many mobile phone models offer changeable faceplates to allow users to customise their phone more fully.
Fast Charging - Refers to a method of fully charging batteries in only a few hours.
Freeware - Software that is free to download and use. This can vary in quality from basic programs & games to much more complex ones.
Frequency - The rate at which an electrical current alternates, usually measured in Hertz (Hz). Also the way to note a general location on the radio frequency spectrum such as 800 MHz, 900 MHz or 1900 MHz.
GPRS - (General Packet Radio Service). Data communications upgrade for GSM networks that enables a maximum data rate of up to 115kbps on a continuous data connection.
When using GPRS, charges are based on the volume of data that you send and receive. You can access around 1000 WAP pages for each megabyte (MB).
GSM - Global System for Mobile Communications. A digital cellular communications standard used throughout Europe, and elsewhere around the world. The standard is used in three frequency bands - 900MHz, 1800MHz, and 1900MHz. In the UK, the term GSM is commonly used to mean GSM900 - while GSM1800 networks are often referred to as PCNs.
GSM900 - GSM network operating in the 900MHz band as used by BT Cellnet and Vodafone in the UK, and by more than 100 countries around the world.
GSM1800 - GSM network operating in the 1800MHz band as used by Orange and One 2 One in the UK, and by a small but growing number of countries around the world.
GSM1900 - GSM network operating in the 1900 MHz band as used in several states in the USA plus parts of Canada and South America.
GPS - (Global Positioning System). A worldwide radio-navigation system formed from a constellation of satellites, which enables users with suitable equipment to identify their geographic location.
Hand-over or Hand off - The automatic transfer of a call from one cell site to another as the user moves through the service area
Hands-free - An important safety feature that's included with most of today's mobile phones. It permits drivers to use their cellular phone without lifting or holding the hand-set to their ear. Available as an accessory for most mobile phones.
Handset - A mobile phone is often referred to as a handset. Handsets are heavily subsidised when purchased with an airtime agreement.
Handset Memory - The memory built in to the mobile phone which you can use to store information. Many handsets now use dynamic memory which you can use for what you want rather than having preset allocations for different types of files or information. Some handsets will have the option to add a removable memory card for additional storage.
HSCSD - High Speed Circuit Switched Data. An enhancement to GSM networks that enables data speeds to be boosted from 9.6kbps in multiples up to 57.6kbps, by combining timeslots. Orange has begun to use HSCSD for certain services.
HTML - (Hypertext Mark-up language). The language in which WWW pages are written
HTML Browser - A program which allows the user to view HTML pages
HZ - (Hertz). The unit of frequency measurement equal to one cycle per second. Abbreviated Hz and named after Heinrich R. Hertz. See also MHz (Megahertz).
Icons - Simple pictures that represent a menu option on some mobile phones.
In Car Charger - This enables you to charge your phone while driving by plugging it into your cars cigerette / power point.
In Car Kit - A full hands free car kit provides radio mute and voice dialling features. An alternative to a full hands free car kit is an easy-to-use mobile holder, which can be used with a mobile charger and a Plug-in Hands Free Car Kit.
Infrared Data Port - A data port that uses infrared data association irDA(r) as the standard for wireless communications between computer and mobile phone devices. For example, to update the phone list on your irDA(r)-enabled PC, you would line up the infrared ports on each device and then transfer the phone information to your PC. Many of the latest mobile devices incorporate IrDA ports for cable free data transmission, via infrared light. Unlike Bluetooth, data transmission is point-to-point, requiring the ports to be lined up. Phones with infrared cannot connect handheld PC's or laptops to the Internet unless it also has a built-in modem
