3G
3G Stands for 3rd-generation. Analogue cellular phones were the
first generation. Digital marked the second generation.
3G is loosely defined, but generally includes high data speeds,
always-on data access, and greater voice capacity. The high data speeds
are possibly the most prominent feature, and certainly the most hyped.
They enable such advanced features as live, streaming video.
There are several different 3G-technology standards. The most prevalent
is UMTS, which is based on WCDMA. (WCDMA and UMTS are often used
interchangeably.)
Alarm
An alarm feature which can be set for a specific time and date or can
used as a daily alarm.
If the phone has a calendar feature, the alarm feature may be integrated
with that (in some Motorola phones for example), so an alarm is simply a
calendar event. Although some phones with a calendar feature also have a
separate alarm feature.
Alphanumeric Display
A display capable of containing letters and numbers, but not graphics.
Bluetooth
A wireless personal area network (PAN) specification that connects
phones, computers, appliances, etc. over short distances without wires
by using low power radio frequencies.
Bluetooth allows you to leave your phone in your pocket, while talking
on your phone with a Bluetooth headset - with no wires. You can also
exchange contact or scheduling information with other Bluetooth-enabled
phones nearby, or send such information to a nearby Bluetooth-enabled
printer.
Calendar
Calendar feature allows you to store scheduling and event information in
your phone. Some phones also offer the ability to sound an alert to
remind you of upcoming events.
CDMA
Code Division Multiple Access. A type of digital wireless technology
that allows large amounts of voice and data to be transmitted on the
same frequency. CDMA is second-generation cellular technology (or 2G)
and is available in Canada, the United States, Pacific Asia, and Latin
America. Most CDMA service providers will migrate to a high-speed data
technology called 1xRTT.
Dual-band
Phones that can switch between two different bands of frequencies.
In Europe Dual-band usually means GSM900/GSM1800 capable phone, while in
USA it might mean GSM850/GSM1900 or combination of two other bands.
EDGE
Enhanced Data rates for Global Evolution. A technology being promoted by
the TDMA and GSM communities that is capable of both voice and 3G data
rates up to 384 Kbps. The standard is based on GSM standard and uses
TDMA multiplexing technology.
EMS
Enhanced Message Service. An extension of SMS that enables the sending
of a combination of simple melodies, images, sounds, animations and
formatted text as a message to another EMS-compatible phone
GPRS
General Packet Radio Service. A packet-switched technology that enables
high-speed wireless Internet and other data communications. GPRS offers
a tenfold increase in data speed over previous technologies, up to
115kbit/s (in theory). Typical real-world speeds are around 30-40 Kbps.
Using a packet switching, subscribers are always connected and always
on-line. GPRS is considered a 2.5G technology.
GPS
Global Positioning System. A system of satellites, computers, and
receivers that is able to determine the latitude and longitude of a
receiver on Earth by calculating the time difference for signals from
different satellites to reach the receiver.
GSM
Global System for Mobile communications. The international digital radio
standard created by the European Telecommunications Standards Institute.
GSM is currently the dominant 2G digital mobile phone standard for most
of the world.
HSCSD
High Speed Circuit Switched Data. An enhancement to GSM networks that
enables data speeds to be boosted from 9.6 Kbps in multiples up to 57.6
Kbps.
iDEN
iDEN stands for Integrated
Digital Enhanced Network, introduced by Motorola in 1994. The Motorola
iDEN is a handset that incorporates four technologies into one. The iDEN
Motorola cell phones are pocket-sized, but pack a Moto punch with a
two-way digital radio and digital wireless, alphanumeric messaging, and
data/fax capabilities using Internet technology.
IMEI
International Mobile Equipment Identity. A unique serial number used on
digital mobile phones.
Infrared port (IrDA)
Allows cell phones, PDAs, and other devices to connect to each other for
various purposes. Infrared is a wireless technology that uses a beam of
invisible light to transmit information.
Java (J2ME)
Java 2 Micro Edition. A feature that allows the device to run specially
written applications. J2ME applications can provide specific functions
such as a tip calculator, they can be games, or they can be
custom-written corporate applications. Some phones allow you to download
new applications directly from Internet while others require a data
cable to transfer the applications from a PC.
LCD
Liquid Crystal Display. LCD displays utilise two sheets of polarising
material with a liquid crystal solution between them. An electric
current passed through the liquid causes the crystals to align so that
light cannot pass through them.
Monochrome LCDs in phones usually have both a backlight and a reflective
backing, allowing them to be equally usable in both bright light and
complete darkness.
Colour LCDs come in many types. STN, TFT, and TFD are several common
technologies used.
Li-Ion battery
Lithium-Ion type of battery, often used to power wireless communication
devices. Considered superior to NiCd and NiMH batteries - they are
lighter weight, have a relatively long cycle life and generally do not
suffer from "memory" effect.
Li-Po battery
Lithium Polymer type of battery. Similar to Li-Ion batteries, but
slightly lighter and the batteries can be moulded to any shape.
MMS
Multimedia Messaging Service. A further extension of SMS and EMS. MMS is
designed to make use of newer and quicker mobile transmission methods
such as GPRS, HSCSD, EDGE and UMTS, involving the attachment of
multimedia extensions to messages, such as video and sound.
Network Lock
A network lock only allows the use of the phone with specific networks.
Nokia BB5 phone
What is BB5? It is a new platform what Nokia use in new products. After review it looks similar to WD2 platform (ex. 6600).
The heart of BB5 is the main processor "RAP3G". This name is a codename used by Nokia to describe
the excellent Texas Instrument integrated processor developed for mobile solutions. It's
based on the new technology OMAP 1710(up to 220 MHz).
The following models are in this range: 3250, 6125, 6131, 6270, 6280, 6630, 6680, 6681, 6682, 7370,

OLED
Organic Light-Emitting Diode. A next-generation display technology that
consists of small dots of organic polymer that emit light when charged
with electricity. OLED displays are thinner, lighter, brighter, cheaper
to manufacture and consume less power than the current LCD displays.
Polyphonic Ringtones
Polyphonic ringtones can create multiple tones simultaneously. This
produces a more natural and realistic sound for melodies.
Predictive Text Input
A technology which allows you to enter text by pressing only one key per
letter. The phone will automatically compare all of the possible letter
combinations against a built-in dictionary of words. The current
Predictive Text Input implementations are T9, iTAP and eZiText.
Satellite Phone
A satellite phone is a
telephone-like device that sends radio signals direct to a satellite,
then back to the earth station from where the call can be directed to
the so-called 'Public Switched Telephone Network' or the PSTN that
serves as a cellular network. The Low Earth Orbiting or the LEO is the
most commonly used satellite now. The gateway processes make everything
possible because even if the person is in the middle of nowhere, he can
still access to the satellite phone network, by using compatible
satellite phones. Satellite phones are used globally but the only
exemption is it cannot work indoors
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 information, such as phone directory and
received SMS messages.
SIM Lock
A SIM lock is an electronic lock, that disallows use of simcards from other mobile phone operators in your mobile phone.
SMS
Short Message Service. A service that enables subscribers to send short
text messages (usually about 160 characters) to and from mobile phones.
Speakerphone
or Build-in Handsfree. Allows the phone to be used at a short distance,
without the phone being held next to the face.
