Global System for Mobile communication
- GSM stands for Global System for Mobile communication.
- It's a typical developed by European Telecommunication Standards Institute (ETSI) to explain protocols for second generation (2G) digital cellular networks.
- It had been a replacement for the primary generation (1G) cellular networks.
- The idea of developing GSM originated from a cell-based mobile radio system at the Bell Laboratories within the early 1970s.
- GSM is an open, digital cellular radio network operating in over 200 countries worldwide. It uses narrowband Time Division Multiple Access (TDMA) technology.
- It covers almost complete Western Europe and growing in America and Asia.
- It's not only used for voice calls, it also can be used for data computing and sending text messages.
- A user can connect his GSM-enabled phone together with his laptop to send or receive e-mails, faxes, browse internet, check security etc.
- The GSM standard operates on three different frequencies which are as follows:
- 900 MHz : It had been used by the original GSM system.
- 1800 MHz : It had been used to support the growing number of subscribers.
- 1900 MHz : It's mainly used in the US.

- GSM is extremely secured because its devices and facilities can't be easily duplicated.
- It has an in depth coverage in all over the world
- Clear voice calls and efficient use of spectrum.
Disadvantages of GSM
- The biggest disadvantage of GSM is that multiple users share an equivalent bandwidth. This might cause interference bandwidth limitation occurs.
- The other disadvantage of GSM is that it's going to cause electronic interference. That's the reason why sensitive locations like hospitals and airplanes require telephone to be turned off otherwise it can create interference with the equipments of hospitals and airplanes.
