GSM 1800 MHz (DCS)


GSM 1800 MHz, also known as DCS 1800, operates within the 1.8 GHz frequency band. It was introduced in 1991 as an extension of the GSM standard and is primarily used in Europe. The frequency ranges for GSM 1800 are:

  • Uplink: 1710–1785 MHz
  • Downlink: 1805–1880 MHz

This band offers reduced signal interference and greater channel availability compared to the more crowded 900 MHz and 1800 MHz bands used by GSM. DCS 1800 provides services such as voice communication, text messaging (SMS), and basic data communications, similar to GSM. It is known for its efficient use of the 1.8 GHz band through modulation schemes like Time Division Multiple Access (TDMA) and Frequency Hopping Spread Spectrum (FHSS).
