What is the full form of GSM?
The GSM full form is the Global System for Mobile Communication. The European Telecommunication Standards Institute (ETSI) created GSM to provide protocols for 2G networks. It functioned as an alternative to 1 G cellular networks.
In essence, GSM is an open, digital cellular radio network that operates in almost every nation. GSM is utilized for communications and data storage in addition to voice conversations.

GSM characteristics
- GSM employs narrowband TDMA (Time Division Multiple Access) techniques for signal delivery.
- Every 200 kHz channel in the circuit-switching program GSM is divided into eight 25 kHz time slots.
- GSM uses the 900 MHz and 1800 MHz mobile communication bands in the majority of the world’s regions.
The GSM network’s structure
The entire performance of the GSM network is achieved through the cooperation of four separate components.
- Mobile phone.
- NSS – The Network switching subsystem.
- BSS – The base station subsystem.
- OSS – The Operation and support subsystem.
The three frequencies primarily implement the GSM system.
- 900 MHz – Used with original GSM.
- 1800 MHz – Used to assist the enhanced subscriber growth.
- 1900 MHz – Used mainly in the US.
Benefits of GSM
- Because all the data is kept on a sim card, it is challenging to duplicate the services, making it secure.
- It works with a lot of different apps.
- allows for the usage of voice calls and data simultaneously, in contrast to CDMA technologies.
- The voice service’s intelligibility is another intriguing and difficult feature.
The drawbacks of GSM
- Multiple users using the same bandwidth can cause interference to the broadcast.
- Utilizing more recent cellular networks, such as 3G, is CDMA technology.
- GSM uses pulse transmission technology, which has the potential to interfere with electronic gadgets. We are encouraged to keep our cell phones in airplane mode to prevent this electronic interference when in hospitals and on airplanes.
- A sophisticated system, GSM.
