GSM – GSM Full Form, GSM Architecture PDF, GSM Technology

GSM Full Form is Global System for Mobile communication. The idea of ​​GSM was developed in 1970 at Bell Laboratories. GSM is an open and digital cellular technology that is used to run mobile voice and data services on the 850MHz, 900MHz, 1800MHz and 1900MHz frequency bands.

In Europe and Asia, GSM operates in the 900 to 1800 MHz frequency range, while in the United States and other US countries, it operates in the 850 to 1900 MHz frequency range. It uses a digital air interface in which analog signals are converted into digital signals before transmission. The transmission speed is 270 kbps.

The GSM system was developed as a digital system using Time Division Multiple Access (TDMA) technology for communication purposes. GSM digitizes and reduces the data, then sends it down through a channel with two separate streams of client data, each in its own particular time slot. Digital systems have the ability to carry 64 kbps to 120 mbps data rates.
