The acronym GSM is derived from the English term Global System for Mobile communications, and is nothing more than a standard mobile phone program, established through a combination of terrestrial and satellite antennas. People who use this system have the possibility of having a connection from their mobile phone to their computer, and sending messages by email, surfing the Internet, in addition to using other digital data transmission functions, which covers the sent text messages. Originally GSM arises in France by the Groupe Spécial Mobile.

Although its basic function was that of telephony, in the same way that previously the telephone line could be used for the modem, GSM also makes it possible to transmit data through its channels, as long as they are free. As it is a standard system, it can be used anywhere that has coverage, even in an international context.

Mobile phones with GSM technology are known as 2G or second generation mobile phones, 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 greater speed.

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 (GSM) network, without any problem. This happens because the 3G and 4G infrastructures have been designed on top of the 2G ones that already existed, following the latter 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 also making it unnecessary to use a fixed terminal to be able to use any information found on the network. Many of its applications have been great, and they will surely continue to bring many technological innovations to users for a long time to come.
