Cell phones are not immortal. And they are continuously updated. Purchasing a cell phone is very prevalent nowadays. But quite a few of us don’t know too a lot about the Most Frequently-Used Cell Phone Glossary.

General understanding of the most typical-used phones terminology could make us successfully enhance our using efficiency and decrease the rate of being cheated by wholesale mobile phones and retails when we buy maximally. The following are the most regularly-used terminology collected from different internet sites:

– 91G – First-generation wireless analog technologies standards which inaugurated in the 1980s.2G – Second-generation wireless digital technologies.2.5G – Protocols extend 2G systems to provide extra features such as packet-switched connection and enhanced data rates.3G – An ITU specification for the third generation of mobile communications technology. It promises increased bandwidth, up to 384 Kbps when a device is stationary or moving at pedestrian speed, 128 Kbps in a vehicle, and 2 Mbps in fixed applications. 3G will work over wireless air interfaces such as GSM, TDMA, and CDMA. The new EDGE air interface has been developed specifically to meet the bandwidth requirements of 3G.4G – Entirely new evolution and a complete 3G replacement in wireless communications. It promises voice, data and high-quality multimedia in real-time form all the time and anywhere.1.5-Way Paging – Guaranteed message receipt or advanced messaging, ensuring subscribers receive messages sent when they’re out of range, but users cannot send text pages. Two-way paging enables users to send and obtain.1.7-Way Paging – A paging service that offers more than guaranteed messaging but not as a lot as full two-way paging. The subscriber has limited response messaging, such as canned messages, rather than the capability to create responses.711 – The nationwide number to reach the telecommunications relay service (TRS). TRS enables telephone conversations between people with speech or hearing disabilities and folks without speech or hearing disabilities.

A Activation Fee – The fee charged to turn on a cell phone for operation on the selected carrier network. Airtime – Airtime, or the time spent talking on a cellular telephone. Billing begins when the SEND key is pressed and finishes when the user presses end.

BBand – Range of radio frequencies between two defined limits.BPS (Bits Per Second) – Measure how quick binary digits can be sent via a channel. Broadband – Communications medium that uses wide-band width channels in order to send and receiving big amounts of data, video or voice info.

CCall Top quality – A measure of the total top quality of a call. It tests the ability to accurately reproduce a users voice, and the systems ability to limit impairments in the course of the course of a conversation.Carrier – The company that provides wireless telecommunications services and transmits the frequencies upon which the cell phone calls, signals and data are carried. CDMA – Code Division Multiple Access. A numerous access technique, using sequenced code to divide traffic channels within the same radio channels.

DDual-Band – a wireless phone which is able to operate on both 800MHz and 1900MHz digital networks to send and receive calls.Dual Mode – Can be operated on analog or digital transmission networks.

EEDGE – Enhanced Data Rates for GSM Evolution. An enhanced modulation technique developed to increase network capacity and data rates in GSM networks. EDGE ought to provide data rates up to 384 Kbps. EDGE makes it possible for operators without a 3G license to compete with 3G networks which provide comparable data services.

FFCT (Fixed Cellular Terminal) – Also known as: GSM Gateway, GSM Modem, GSM Router, Mobile Gateway, channel bank, GSM channel Bank, ISDN GSM Gateway, analogue GSM gateway.

GGPRS – General Packet Radio Service. Data communications upgrade for GSM networks, enabling a maximum data rate of up to 115kbps. GSM (Global System for Mobile Communication) – Communication standard in three frequency bands viz. 900MHz, 1800MHz and 1900MHz. The term GSM is typically employed in the UK to refer to the 900MHz band even though the 1800MHz band is referred to as PCN.

HHSCSD (High Speed Circuit Switched Data) – A GSM enhancement which makes it possible for access to data services at up to 57.6kbps.

IIMEI (International Mobile Equipment Identity) – A special identity number given to GSM mobile phones and can be employed to block mobile phones that have been stolen when reported to the network operator.

JJava – A universal software platform developed. J2ME – Java 2 Platform Micro Edition. It is designed to run on modest devices such as mobile phones and PDA’s.

PPredictive Text Input – Allows users to write text messages with the aid of an integrated dictionary. The dictionary offers possible word matches as the beginning of the word is typed.PTT – Push to talk. A two-way mobile technology that works like a walkie-talkie.

QQuad-band – Enables users to roam almost anywhere globally. It covers 850 MHz, 900 MHz, 1800 MHz and 1900 MHz frequency.

SSmart phone – A handheld device. It integrates different cell phones and PDA capabilities. SMS – Short Message Service. It enables messages of up to 160 characters to be sent between phones on any network.

TTri-band – Mobile phones which operate on three GSM frequency bands: GSM900, GSM1800 and GSM1900.

WWAP – Wireless Application Protocol. An agreed standard which enables compatible mobile phones to access Internet-type services like news and sport.
