QCIF |
Data transfer rate is a quarter of the Full CIF. The QCIF
(Quarter Common Intermediate Format) standard is defined as 176
x 144 resolution frames transferred at 9.1Mpbs.The QCIF is
suitable for videoconferencing by telephone lines. |
|
Quartz |
Code-name for a tablet-like, quarter-VGA portrait
screen size, pen-based, reference design. |
|
QoS |
Quality of Service. A measure of how reliable a
carrier’s service is. Usually expressed in terms of availability
and measured, as how often available, by .99999 or five nines,
which is the top level of reliability. |
|
Reviewed Unit |
Reviewed unit is the items used to review the product. We at
iMobile received reviewed units from different companies and do
our best to give our honest opinions to our readers about the
products we are reviewing. |
|
Roaming |
A service offered by most mobile phone service providers that
allows subscribers to use mobile service while traveling outside
their home service area. When they are outside their home
service and come within range of another mobile system, the ROAM
indicator on the mobile phone will indicate that they are in
range. |
|
Reference design |
User interface designs for Symbian OS delivered
to Symbian licensees. |
|
RACE |
Research and Development in Advanced
Communications Technologies in Europe. |
|
Registration |
The procedure that a cellular phone initiates to
a base station to indicate that it is now active. |
|
RF |
Radio Frequency. |
|
RLL |
Radio in the Local Loop. |
|
SIM |
(Subscriber Identity Module) The smart card used in digital
phones. It carries the user's identity for accessing the network
and receiving calls and also stores personal infromation, such
as phone directory and received SMS messages. |
|
Standby Time |
The number of hours that a freshly-charged battery will keep a
mobile phone running without making or receiving a call. When
making or receiving a call. When it is switched on, power is
used continuously by the phone to keep it in contact with the
local station. |
|
SAR |
In a packet-switched telecommunication network, segmentation and
reassembly (SAR, sometimes just referred to as segmentation) is
the process of breaking a packet into smaller units before
transmission and reassembling them into the proper order at the
receiving end of the communication. Packets are made smaller to
speed them through the network and specifically because of
specified packet size restrictions in a given path. In the Open
Systems Interconnection (OSI) model, SAR is performed in the
Transport layer at both ends. A transport protocol determines
the size of the smallest maximum protocol data unit (PDU)
supported by any of the involved networks, and segments the
packets accordingly. SAR is used for asynchronous transfer mode
(ATM) communications. In TCP/IP, the same process is known as
fragmentation. |
|
SDIO |
SDIO (Secure Digital Input/Output), allow an SD Slot to be more
then just a memory slot, letting compatible devices such as
camera, communication cards etc to be plug into it for usage. |
|
STN (display) |
STN (Super Twisted Nematic Liquid Crystal Displays) is one of
the first colour mobile handset's displays available. However,
it’s not as bright and not as good quality to its newer
successors TFT and UFB displays. |
|
Service Provider |
A company that buys airtime from a network and re-sells it to a
customer. |
|
Sim Tool Kit |
With Network support the SIM toolkit enables you to receive a
wide range of essential information. Anything from travel
reports to sports results. |
|
SmartPhone |
A generic name for voice centric mobile phones
with information capability. The Ericsson R380 Smartphone is an
example of such a Symbian OS phone. |
|
SMS |
Short Message Service: available on digital GSM
networks allowing text messages of up to 160 characters to be
sent and received via the network operator's message center to
your mobile phone, or from the Internet, using a so-called "SMS
gateway" website. If the phone is powered off or out of range,
messages are stored in the network and are delivered at the next
opportunity. |
|
Symbian Connect |
The PC-based Symbian Connect is a system for data
synchronization, file management, printing via PC, application
installation from a PC, and other utility functions allowing
Symbian OS phones to integrate effectively with PC and
server-based data. |
|
Symbian Developer Network |
The developers' support network for Symbian OS,
where you will find all the resources to enable you to develop
world-class applications for Symbian OS phones. |
|
Symbian OS |
Symbian’s advanced open standard operating system
for data enabled mobile phones. It includes a multi-tasking
multithreaded core, a user interface framework, data services
enablers, application engines and integrated PIM functionality
and wireless communications. |
|
SyncML |
Synchronization Markup Language, an industry-wide
effort to create a single, common data synchronization protocol
optimized for wireless networks. SyncML's goal is to have
networked data that support synchronization with any mobile
device, and mobile devices that support synchronization with any
networked data. The SyncML structured data layer will use XML
wherever appropriate. SyncML is intended to work on transport
protocols as diverse as HTTP, WSP (part of WAP) and OBEX, and
with data formats ranging from personal data (e.g. vCard &
vCalendar) to relational data and XML documents. The SyncML
consortium was set up by IBM, Nokia and Psion among others.
Symbian is a sponsor of the SyncML consortium. |
|
SAW filter |
Surface Acoustic Wave filter. A filter that uses
surface elastic waves that are transmitted across the surface of
a piezoelectric material. This implements a filter that has the
resonant frequency and its vicinity as the pass band. |
|
SGS |
Server GPRS Support Nodes. |
|
SID |
System Identification. A five-digit number that
indicates which service area the phone is in. Most carriers have
one SID assigned to their service area. |
|
SNR |
Signal to Noise Ratio. The difference in strength
between the signal we want to receive and the background noise
(or any unwanted signal). |
|
SP-lock |
A lock placed on a cellular phone by some service
providers to ensure that subscribers can only use the phone with
the carrier’s service. |
|
SSL |
Secure Socket Layer. |
|
Speech Recognition |
A software application that can recognize spoken
speech – a human voice. Voice recognition applications do not
understand what the content of the speech means – however, they
can recognize specific commands, such as “Call Jane Smith”, and
perform specific actions based on those commands. Over the last
few years, speech recognition technology has improved
dramatically – early efforts were marked by poor accuracy and a
need to speak slowly – current products recognize many different
commands, as well as different speaking styles and accents. |
