Explanation:

  • Since GSM and CDMA platforms co-exist in India, the 900 MHz band is truncated and called 'primary GSM' as the higher frequencies of the 800 MHz band (880-890 MHz) are allocated to CDMA operators.
  • Therefore, the 900 MHz band allocated to GSM operators in India is smaller than the EGSM band available overseas.
  • GSM frequency bands or frequency ranges are the cellular frequencies designated by the ITU for the operation of GSM mobile phones and other mobile devices.
  • A dual-band 900/1800 device is required to be compatible with most networks apart from deployments in ITU Region 

 

GSM-900, GSM-1800

  • GSM-900 and GSM-1800 are used in most parts of the world (ITU-Regions 1 and 3)
  • AfricaEuropeMiddle EastAsia (apart from Japan and South Korea where GSM has never been introduced), and Oceania.
  • In common GSM-900 is most widely used. Fewer operators use GSM-1800.
  • Mobile Communication Services on Aircraft (MCA) uses GSM-1800.
  • In some countries, GSM-1800 is also referred to as the "Digital Cellular System" (DCS).

 

In India, we use 900 MHz and 1800 MHz frequency.
