GSM Full Form: What is the full form of GSM?

GSM full form means Global System for Mobile and also called Global Mobile Communication System. If you are in Europe or Asia and are using a mobile phone, then you will probably be using GSM technology on your mobile phone.

GSM Full Form

It is a digital cellular technology that is used to transmit mobile voice and data services. In the early 1970s, the concept of GSM(GSM Full Form) emerged from a cell-based mobile radio system at Bell Laboratories.

Global Mobile Communication System (GSM Full Form) Works?

GSM is the name of a standardization group established in 1982 to create a common European mobile telephone standard. GSM is the most widely accepted standard in telecommunications and is applied globally.

GSM is a circuit-switched system that divides each 200 kHz channel into eight 25 kHz time-slots. The GSM mobile communication band operates at 900 MHz and 1800 MHz in most parts of the world.

In the US, GSM operates in the 850 MHz and 1900 MHz bands. GSM has more than 70 percent of the world’s digital cellular subscribers.

GSM uses Time Division Multiple Access (TDMA) technology to transmit signals. GSM was developed using digital technology. It has the capability to carry data rates from 64 Kbps to 120 Mbps.

Currently, GSM supports over one billion mobile subscribers in more than 210 countries worldwide.

Global Mobile Communication System (GSM Full Form) provides basic to advanced voice and data services including roaming services. Roaming Another GSM network has the ability to access your GSM phone number.

GSM digitizes and compresses the data, then sends it through one channel with two other streams of user data, each in its own time.
