GSM-1800 mobile phone

Belongs to:
GSM mobile phone
Synonyms:
DCS-1800 mobile phone
Description:

In 1991, extension of the GSM standard of the second generation of mobile communication systems into the 1800 MHz frequency range took place. Since 1995, short message service (SMS) and further data transmission services are open to customers in the GSM standards. Frequencies from 1710 MHz - 1785 MHz are used for the uplink and frequencies from 1805 MHz - 1880 MHz for the downlink.
GSM 1800 was formerly called DCS 1800 and is mainly used in Europe.

Frequency ranges:
  • 1,710–1,785 MHz (uplink in the DCS 1800 frequency band)
  • 1,805–1,880 MHz (downlink in the DCS 1800 frequency band)
Type of field:
electromagnetic
