Frequency Result

Calculation Formula

f(MHz) = 925 + (ARFCN - 905) / 3 for GSM 900/1800 MHz bands

f(MHz) = 1920 + (ARFCN - 935) / 5 for UMTS bands (1900 MHz, 2100 MHz)

Where:
f = Frequency in MHz
ARFCN = Absolute Radio Frequency Channel Number

Understanding ARFCN

ARFCN (Absolute Radio Frequency Channel Number) is a unique identifier for radio channels in mobile communication systems. It's used to map a specific radio frequency to a channel number across different regions and bands.

Band Coverage

  • GSM 900 MHz Band: ARFCN range typically from 905 to 1000
  • GSM 1800 MHz Band: ARFCN range typically from 1710 to 1790
  • UMTS 1900 MHz Band: ARFCN range typically from 935 to 960
  • LTE 850 MHz Band: ARFCN range typically from 512 to 610
  • LTE/UMTS 2100 MHz Band: ARFCN range typically from 969 to 1029
