(Global System for Mobile Communication)

     GSM or global system for mobile communication is a digital cellular system. It was originated in Finland Europe .however now it is throughout the world. GSM (Global System for Mobile Communication) accounts for 80% of total mobile phone technologies market. There are over more than 3 billion users of GSM (Global System for Mobile Communication) now. GSM technology got its popularity, when people used it to talk to their friends and relatives. The use of GSM (Global System for Mobile Communication) is possible due to the SIM (subscribers identity module) GSM (Global System for Mobile Communication) is easy to use, affordable and helps you carry your cell phone everywhere. GSM (Global System for Mobile Communication) is a 2G technology. There are many frequency ranges for GSM (Global System for Mobile Communication) however 2G is the most used frequency. GSM (Global System for Mobile Communication) offers moderate security. It allows for encryption between the end user and the service base station. The use of various forms of cryptographic modules is part of GSM technology.

GSM (Global System for Mobile Communication) Association

 It is an official conglomerate of mobile phone operators. There are 800 regular telephone operators in the association, along with 200 correlated members. Its history draws its way back to 1982. It was when European Union supported the availability and operation of GSM (Global System for Mobile Communication). It is powerful union and makes their own pricing strategies, without having to take dictation from governments.  

GSM (Global System for Mobile Communication) History

In 1982 CEPT in Europe took an initiative to improve mobile networks that could lead its way to a profitable market.13 counties in Europe in 1987 signed an agreement for cellular roaming. European telecommunication standard took the responsibility of launching first GSM (Global System for Mobile Communication) in 1989. It was in 1990 when first GSM (Global System for Mobile Communication) came into existence. However in 1991 Radiolinja from Finland officially launched first GSM (Global System for Mobile Communication) in the market. They were not alone in the effort because building a GSM infrastructure requires huge finance initially. Therefore they seek the cooperation of Ericcson. By the end of two years after its operation GSM (Global System for Mobile Communication) has million users in 48 countries with almost 70 carriers.

Application of GSM (Global System for Mobile Communication)

Mobile phones connect to the GSM (Global System for Mobile Communication) by locating the cells in the network surroundings. These cells are of five different sizes. These cells include macro, micro, femto, umbrella and Pico cells. Macro cells are the largest cells that cover radio signals. Macro cells are distributed over larger geographical areas. Micro cells cover a small geographical are such as hotels. These cells are supported by powerful cellular stations or in other words tower. Pico cell is a wireless communication scheme. Pico cells also cover a small geographical area. Femto cell is a small base station designed to cater the needs of minor business area. It is connected using DSL technology. Various GSM applications include GSM (Global System for Mobile Communication) modems, GSM terminals, GPRS amalgamation, GSM security, GSM remote monitoring. Application of GSM (Global System for Mobile Communication) is dependent upon its frequency. Some countries in the world use GSM-900 or E-GSM. The frequency in E-GSM is extended to about 920 to 960MHZ.latest mobile phones support E-GSM.GSM technology allows you to use any mobile handset and everywhere.

So while you’re traveling you can replace your SIM (Subscriber Identity Module) and still remain connected to the GSM (Global System for Mobile Communication). this 2G mobile technology has brought a revolution to the mobile technologies. GSM (Global System for Mobile Communication) has provided the base for many advanced 3G technologies like EDGE and UMTS. Thus it is GSM (Global System for Mobile Communication) which has provided us with international roaming and clarity of voice due to its wide infrastructure.
