Understanding EARFCN and Frequency Bands

EARFCN is a numerical identifier for LTE frequency bands that helps in mapping the frequency to a specific channel. The conversion formula used is: Frequency (MHz) = 1920 + EARFCN - 10. This formula is based on the allocation of frequency bands by the International Telecommunication Union (ITU).

The frequency bands commonly used in LTE are:

  • Band 3: 1920-2170 MHz
  • Band 4: 2185-2200 MHz
  • Band 5: 2300-2320 MHz
  • Band 13: 2497-2572 MHz
  • Band 26: 2575-2620 MHz

This calculator helps in converting an EARFCN value to its corresponding frequency and band, which is useful for network planning, deployment, and troubleshooting.
