GSM Mobile Phones
Mobile phone users usually get to hear the term, "GSM," when talks about mobile phone networks come up. You usually get to read, "this mobile phone is powered by this or that GSM network." But what exactly does GSM mean? Do all mobile phones have GSM? Why is GSM so important to mobile phone users?
What Is GSM?
GSM stands for Global System for Mobile Communication. The acronym can also stand for Groupe Special Mobile. As the name connotes, it is a system that enables the transmission of data and voice calls by means of cellular digital wireless technology. Though it is a form of wireless technology, GSM is an edge above it because it allows the user to transmit voice and data to a lot of users across various time divisions. Also, unlike the typical wireless system, GSM makes use of digital technology.
Still unclear? All right, here's a more popular example of what GSM can do. Do you know what roaming is? It allows you to use the same SIM card for your mobile phone when you travel abroad and still be contactable by the people from home. International roaming is just one of the many services that are made possible by GSM.
Who Uses GSM?
GSM is currently the most widely recognised mobile phone system in the world, but its primary clients are European countries, South America, Canada, and Australia. The largest bulk of GSM users is in Asia, with almost a billion users, followed by Eastern Europe, with a user population nearing 400 million.
When Did GSM Come To Fore?
GSM started in the early 80's as the mobile phone standard for the whole of Europe. Its original proponent is the European Conference of Postal and Telecommunications Administration. It was only in the early 90's that GSM became recognised in countries outside of the European continent.
