|
TFT (display) |
TFT (Thin-Film Transistor) is a technology that has a transistor
for each pixel (tiny elements that control the illumination of
your display) in a handset's LCD (liquid crystal display)
screen. Having a transistor at each pixel meant that the current
that triggers pixel illumination can be smaller, faster and
brighter then other method of LCD screen, such as STN displays. |
|
Talk time |
The number of minutes of continuos speech will allow you to make
on a mobile phone. |
|
TDMA |
(Time Division Multiple Access) Type of processing system used
by digital mobile phones that allows several handsets in the
same area to use the same frequency. Each conversation is
allocated its own time slot -so that you only hear the
conversation for the fraction of each second. |
|
TACS |
Total Access Communication System: a British 1G
analog mobile telephone standard based on the US AMPS system. It
was later adopted in other countries including Hong-Kong and

large data transfer (such as FTP, NFS, HTTP 1.1). This speed is
expressed in bits per seconds or a multiple. |
|
TM-UWB |
Time Modulated Ultra Wideband. A method of
wirelessly sending data that indicates 1's or 0's by varying the
time between ultra fast pulses. |
|
TTS |
Text-to-Speech. The flip side of speech
recognition, TTS takes written words and converts them to
speech. Thus, when a caller requests specific information from a
voice portal, such as driving directions, TTS reads the
directions to the caller. Early TTS efforts were slow and were
usually read by a computerized voice that was often referred to
as “Igor” because of its similarity to the voice of the
character of the same name in old horror movies. Current TTS
technology is much more natural sounding, and in some situations
the caller would be challenged to differentiate TTS from an
actual human speaker. |
|
Unconditional Forwarding |
When you choose to divert all calls to another service or phone
number. That is, the diversion is unconditional no matter what
the circumstances. |
|
UFB (display) |

energy-consuming features than TFT-LCDs, and brighter picture
capabilities than STN LCD, allowing up to 65K colour for mobile
handset's displays. |
|
USB |
USB (Universal Serial Bus) is a plug-and-play interface between
a computer and add-on devices (such as audio players, joysticks,
keyboards, mobile phones, scanners, and printers). With USB, a
new device can be added to your computer without having to add
an adapter card or even having to turn the computer off. It
supports a data speed of 12 megabits per second. |
|
UMTS |
Universal Mobile Telecommunications Service, part
of the IMT-2000 initiative, is a 3G standard supporting a
theoretical data throughput of up to 2 Mbps. First trials
started in 2001. It should be rolled out in most of the world by
2005. |
|
Unicode |
A 16-bit character encoding scheme allowing
characters from Western European, Eastern European, Cyrillic,
Greek, Arabic, Hebrew, Chinese, Japanese, Korean, Thai, Urdu,
Hindi and all other major world languages, living and dead, to
be encoded in a single character set. The Unicode specification
also includes standard compression schemes and a wide range of
typesetting information required for worldwide locale support.
Symbian OS fully implements Unicode. |
|
UWB |

by vibrating. |
|
Voice Record |
The ability of a phone to record the conversations on a call for
playback later. |
|
Voice Recognition |
Facility offered by a few handsets enabling calls to be made by
using voice commands rather than pressing the numbers. The
memory can be programmed to store and identify names spoken into
the handset and call numbers associated with them. |
|
Voice Mail |
Mobile phone service provided by the networks that records a
message for you when you can't, or don't want to answer a call. |
|
Voicemail Box Number |
This is the number of the "mailbox" where voice messages are
left when CALL back is activated. Different to your mobile
number, this is the number you need to call to access messages
from a phone other than your mobile handset. |
|
Value Added Services |
Additional services which add value to those already available
on the network. |
|
vCalendar |
Defines a transport- and platform-independent
format for exchanging calendar and schedule information so that
any vCalendar-compliant application can send or receive
calendaring and scheduling information to or from any other
vCalendar-compliant application. For instance, users with mobile
phones running vCalendar-aware applications can schedule
meetings automatically over an infrared link or via sending an
SMS. |
|
vCard |
Standard defining the format of an electronic
business card. All devices supporting vCard can exchange
information such as phone numbers and addresses. For instance a
user with a vCard-aware phonebook application on a handheld
computer can easily transfer names and phone numbers to a
vCard-aware mobile phone. |
|
VGA |
Video Graphics Array: “standard” screen size of
640 by 480 pixels. |
|
VoiceChannel |
The channel a caller is assigned by the switch to
commence the call on after the exchange of subscriber data. |
|
VoicePortal |
A voice portal is a software application that
uses speech recognition technology to provide information to
callers. Using a combination of speech recognition and
text-to-speech technology, the application lets callers request
specific information, such as news, weather, traffic reports, or
email, which is read by the application, to the caller. Voice
portals can also allow callers to conduct transactions, such as
trade stocks or manage bank accounts. Callers can also use voice
portals to purchase products or services. Voice portals
essentially allow callers to perform functions that they might
otherwise do using the Internet or other methods. Additionally,
the application can be used to authenticate callers by matching
their “voiceprint” to one on file, for security purposes. |

Wireless Application Protocol (WAP) 1.2.1 is a technology
designed to provide users of mobile devices with rapid and
efficient access to the Internet. WAP is a protocol optimized
for low speed wireless network and for the limited display
capabilities by today’s mobile devices. WAP integrates telephony
services with micro browsing and enables easy-to-use interactive
Internet access from the mobile handset. Today's web contents
are not optimised for mobile access. WAP contents are typical
written in a less heavy language in WML. Typical WAP
applications include information provisioning, messaging,
m-commerce transactions and online banking. |
