GSM is the most popular method that uses all over the world for mobile communication. Before going into the details of the GSM System it is worthy to have some understanding about the history of GSM.

History of GSM in brief

  • In 1982-85 Conférence Européenne des Postes et Télécommunications (CEPT) began specifying a European digital telecommunications standard in the 900 MHz frequency band. This standard later became known as Global System for Mobile communication (GSM).

  • In 1986 field tests were held in Paris to select which digital transmission technology to use. The choice was Time Division Multiple Access (TDMA) or Frequency Division Multiple Access (FDMA).

  • In 1987 a combination of TDMA and FDMA was selected as the transmission technology for GSM.
