| Our glossary of terms is a specially chosen list of words, acronyms and abbreviations that all relate in some way to mobile telecommunications |
| GPS |
GPS has become a mainstay of transportation systems worldwide, providing navigation for aviation, ground, and maritime operations. Disaster relief and emergency services depend upon GPS for location and timing capabilities in their life-saving missions. Everyday activities such as banking, mobile phone operations, and even the control of power grids, are facilitated by the accurate timing provided by GPS. |
| Bit |
| A binary digit. The values of a bit are either "0" or "1". |
| GPRS |
| General Packet Radio Service is a packet-switching technology that enables data transfers through cellular networks. |
| LCD |
Liquid crystal display is the most common display type among mobile phones because of its low power consumption and good image quality. They are generally easy to read,even under direct sunlight.The smallest element of an image displayed on a LCD is the pixel.Each pixel normally consists of a layer of molecules aligned between two transparent electrodes,and two polarizing filters.Some of the types of LCD displays are STN,TFT and TFD.The first one, STN, offers low cost and low power consumption,but low image quality.TFT features greater image quality and response time,yet its displays are more expensive and need more power. |
| MMS |
Multimedia Message Service is a store-and-forward method of transmitting graphics, video clips, sound files and short text messages over wireless networks using the WAP protocol. Carriers deploy special servers, dubbed MMS Centers (MMSCs) to implement the offerings on their systems |
| SMS |
SMS messages may be sent either from one point to another point, or may be sent to all devices within a specific geographical region. The former, known as SMS-PP, is used primarily between individuals communicating with one another, while the latter, known as SMS-CB, may be used to broadcast public announcements such as road or weather conditions, region-specific advertising messages, or messages from a cell provider regarding the new coverage area. |
| 3G |
| 3G refers to the third generation of mobile telephony (that is, cellular) technology. The third generation, as the name suggests, follows two earlier generations |
| TFT |
| A TFT monitor uses thin-film transistor technology for the ultimate LCD display.LCD monitors,also called flat panel displays,are replacing the old style cathode ray tubes (CRTs) as the displays of choice.Nearly all LCD monitors today use TFT technology |
| Browser |
| A piece of software that allows the user to access Internet sites.Most current handsets are equipped with browsers capable of viewing common websites (those intended for a desktop browser). |
| Bluetooth |
| Well it isn't some strange form of tooth decay as you might initially imagine.Bluetooth is the name of a new technology that is now becoming commercially available.It promises to change significantly the way we use machines |
| Alphanumeric |
| Describes the combined set of all letters in the alphabet and the numbers 0 through 9.It is useful to group letters and numbers together because many programs treat them identically,and differently from punctuation characters |
|
| Li-Ion |
This stands for a type of rechargeable battery. They are much lighter than earlier battery types (NiCd and NiMH),have a long life cycle and generally don't suffer from the so-called "memory effect". |
| Bits per Second |
| In data communications,bits per second (abbreviated bps or bit/sec) is a common measure of data speed for computer modems and transmission carriers.As the term implies,the speed in bps is equal to the number of bits transmitted or received each second. |
| Bar |
| The bar form factor is the most common and simple form factor for a mobile phone. |
| Byte |
| A string of 8 bits. |
| WAP |
| Short for the Wireless Application Protocol,a secure specification that allows users to access information instantly via handheld wireless devices such as mobile phones,pagers,two-way radios smartphones and communicators. |
| GSM |
| Global System for Mobile communication is a digital mobile telephony system that is widely used in Europe and other parts of the world.GSM digitizes and compresses data,then sends it down a channel with two other streams of user data,each in its own time slot.It operates at either the 900 MHz or 1800 MHz frequency band. |
| SIM |
| Subscriber Identity Module holding home network access configurations may be switched to those will metered local access, significantly reducing roaming costs while experiencing no reductions in service. |
| EDGE |
| A data system used on top of GSM networks.It provides nearly three times faster speeds than the outdated GPRS system,it is a modulation technique for GSM networks.An Enhanced DataRates for GSM Evolution(EDGE) is used to increase network capacity and data rates in mobile networks.EDGE provides data rates up to 384 Kbps. |
| CDMA |
| Short for Code-Division Multiple Access,a digital cellular technology that uses spread-spectrum techniques.CDMA consistently provides better capacity for voice and data communications than other commercial mobile technologies,allowing more subscribers to connect at any given time,and it is the common platform on which 3G technologies are built. |
| Megapixel |
| A megapixel refers to one million pixels,and is commonly used in reference to digital cameras as an indication of resolution capability.A pixel is a tiny square on a computerized display that is so small it appears as a dot.The display screen is a solid grid of these squares or dots,which can be easily seen with a magnifying glass. |
