The acronym GSM is derived from the English term Global System for Mobile communications, and it is nothing more than a standard mobile telephone program, established by means of a combination of terrestrial antennas and satellites. People who use this system have the possibility of having a connection from their mobile phone with their computer, and send messages by e-mail, surf the Internet, in addition to using other data transmission functions digitally, which includes the sending text messages. GSM was originally created in France by Groupe Spécial Mobile.
Although its basic function was that of telephony, in the same way as previously the telephone line could be used for the modem, also the GSM makes it possible to transmit data through its channels, provided that they are free. As it is a standard system, it can be used anywhere with coverage, even in an international context.
Mobile phones with GSM technology are known as 2G or second generation mobiles, however, they are currently being replaced by other more advanced technologies such as third and fourth generation (3G) (4G), which use the UMTS standard. which provides faster.
However, the introduction of these new systems has not completely displaced 2G networks, but rather coexists with them. Most of these new mobiles allow you to use both networks, in such a way that if there is no 3G coverage in a place it is possible to use the 2G network (GSM), without any inconvenience. This occurs because the 3G and 4G infrastructures have been designed on top of the existing 2G ones, the latter continuing in operation.
GSM technology came to innovate the world's mobile platforms, making it possible for many people not only to be able to communicate from anywhere, but it is also unnecessary to use a fixed terminal to be able to use any information found on the network. Many of their applications have been great, and they will surely continue to bring many technological firsts to users for a long time to come.
