|
GSM |
(Global System for Mobile Communications) A digital cellular
communications standard used throughout Europe, and Australia.
The standard is used in three distinct frequency bands - 900Mhz,
1800Mhz and 1900 Mhz. In Australia, we use GSM 900Mhz frequency. |
|
Games |
Phones which have a number of games installed in their software. |
|
GPRS |
Genernal packet Radio Service. This is means of data transfer
over the GSM network. Maximum speeds of up to 171.2 kilobits per
second (kbps) are achievable with GPRS using all eight timeslots
at the same time. |
|
Global Roaming |
Global Roaming is the convenience of having a mobile phone to
make and receive calls, send and receive SMS while you travel
overseas with your regular mobile number. |
|
GGSN |
Gateway GPRS Service Nodes. |
|
GHz |
Gigahertz (1,000,000,000Hz) |
|
Handsfree Car Kit |
An accessory for your vehicle which provides a cradle for the
phone, microphone, speaker, external antenna and battery
charging for when you are driving. |
|
HTML Browser |
HTML browsers are used to view web pages written in HTML from
the Internet. Some mobile handsets have a HTML browser installed
to view pages from the Internet using WAP or GPRS. |
|
HSCSD |
High Speed Circuit Switched Data: dedicated
circuit-switched data communications technology for GSM which
boosts data throughput up to 14.4 Kbps in a single channel, and
by aggregating channels, up to 57.6 Kbps. An asymmetrical
service can be offered where, for instance, one channel is
allocated for the uplink and several are aggregated for the
downlink. HSCSD can provide a fixed bit rate (transparent mode)
or a variable one (non-transparent mode). In most cases HSCSD is
available to network operators as a pure software upgrade. HSCSD
started to appear in some networks in 1999. |
|
HDML |
Handheld Device Markup Language. |
|
HTML |
Hypertext Markup Language. |
|
IEEE |
IEEE 1394, High Performance Serial Bus, is an electronics
standard for connecting devices such as mobile phones to your
personal computer. IEEE 1394 provides a single plug-and-socket
connection on which up to 63 devices can be attached with data
transfer speeds up to 400 Mbps (megabits per second). |
|
Interchangeable Covers |
User-changeable housings. Only elected mobile phones have this
capability. |
|
IMEI |
(International Mobile Equipment Identity) A unique serial number
used on digital mobile phones. |
|
Iridium |
A global mobile phone system of 66 satellites that offer global
communications. |
|
In-car Charger |
A device which charges the mobile phone battery from a cigarette
lighter socket in a vehicle. |
|
Internal Hands-free |
A mobile phone which has the hands-free capability built-in,
ideal for when a group of people need to involved in the call,
or when you cannot stop working to take a call. |
|
IR or Infra Red Port |
Infra-Red. The ability to transmit data with out the need for
cables. |
|
ICNIRP |
ICNIRP (International Commission on Non-Ionizing Radiation
Protection) is an independent scientific organisation
responsible for providing guidance and advice on the health
hazards of non-ionizing radiation exposure. ICNIRP develops
international guidelines on limits of exposure to non-ionizing
radiations which are independent and science based. It provides
science based guidance and recommendations on protection from
non-ionizing radiation exposure and establishes principles of
non-ionizing radiation protection for formulating international
and national protection programmes. It is the recognised
non-governmental organisation in non-ionizing radiation for the
World Health Organisation, the International Labour Organisation
and the Commission of the European Union. |
|
IMT-2000 |
International Mobile Telecommunications-2000:
term used by the International Telecommunications Union (ITU)
for the specification for projected third-generation wireless
services. Formerly referred to as FPLMTS, Future Public
Land-Mobile Telephone Systems. |
|
i-Mode |
Proprietary packet-based information service for
mobile phones. i-mode delivers information (such as mobile
banking, and train timetable) to mobile phones and enables
exchange of email from handsets on the PDC-P network. Launched
in 1999 by NTT DoCoMo, i-mode is very popular in Japan
(especially for email and transfer of icons), but is not
currently being used elsewhere. |
|
IrDA |
1. A suite of protocols for infrared (IR)
exchange of data between two devices, up to 1 or 2 meters apart
(20 to 30 cm for low-power devices). IrDA devices typically have
throughput of up to either 115.2 Kbps or 4 Mbps. IrDA protocols
are implemented in Symbian OS phones, many PDAs, printers and
laptop computers.
2. The Infrared Data Association, the industry body that
specifies IrDA protocols, originally founded by Hewlett-Packard
and others. |
|
iDEN |
A modified TDMA technology used by
Motorola and run by Nextel Communications, Southern LINC, and a
handful of other carriers around the world. iDEN phones run on a
different frequency than other cellular services and are
therefore incompatible with them. |
|
IMT |
International Mobile Telephone. |
|
IS-136 |
TDMA Interim Standard 136. |
|
IS-95 |
CDMA Interim Standard 95. |
|
IVR |
Interactive Voice Response: - A
software application, typically used in conjunction with
corporate telephony hardware, which recognizes spoken commands.
Typically used for helping callers navigate corporate
directories and phonebooks or for other types of menu-driven
services. Usually limited in the number of commands that can be
recognized. |
