What is the full form of GSM?

The full form of GSM is Global System for Mobile Communication. The ETSI (European Telecommunication Standards Institute) created GSM to describe protocols for 2 G networks. It served as a replacement for 1 G cellular networks.

GSM is a digital, open cellular radio network that is used in practically every country. GSM is utilised for more than just phone calls; it is also used for data storage and messaging.

Characteristics of GSM

• GSM employs Narrowband TDMA (Time Division Multiple Access) technologies for signal delivery.
• GSM is a circuit-switching programme that divides each 200 kHz channel into eight 25 kHz time slots.
• GSM operates in most parts of the world on mobile communication bands of 900 MHz and 1800 MHz.

Composition of the GSM network

The GSM network has four distinct sections that work together to achieve overall performance.

1. Mobile phone.
2. NSS – The Network switching subsystem.
3. BSS – The base station subsystem.
4. 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.

Advantages of GSM

• It is secure since it is difficult to duplicate services because all data is stored on a sim card.
• It is compatible with a wide range of applications.
• When compared to CDMA technologies, it enables the simultaneous usage of voice and data conversations.
• Another intriguing and hard function is the voice clarity service.

Disadvantages of GSM

• Because numerous users share the same bandwidth, the broadcast may encounter interference.
• CDMA technology is compatible with newer cellular networks such as 3G.
• Because it employs pulse transmission technology, GSM can potentially cause electronic gadgets to malfunction. To avoid electronic interference, we are encouraged to keep our cell phones in aeroplane mode in hospitals and on planes.
• GSM is a sophisticated system.
