Enter the band, downlink EARFCN, and other details into the calculator to determine the uplink EARFCN or other related values.

EARFCN Calculation Formula

The following formula is used to calculate the UL EARFCN from the DL EARFCN and band:

UL EARFCN = DL EARFCN + (2 * Band)

Variables:

  • UL EARFCN is the uplink EARFCN.
  • DL EARFCN is the downlink EARFCN.
  • Band is the frequency band number.

To calculate the UL EARFCN, add the product of the band and 2 to the DL EARFCN.

What is EARFCN Calculation?

EARFCN (E-UTRA Absolute Radio Frequency Channel Number) calculation refers to the process of determining the specific frequencies used for uplink and downlink in LTE networks. This involves understanding the relationship between the band, downlink EARFCN, and other parameters to ensure accurate frequency planning and network performance.

How to Calculate EARFCN?

The following steps outline how to calculate the uplink EARFCN using the given formula.

  1. First, determine your band and downlink EARFCN.
  2. Next, use the formula: UL EARFCN = DL EARFCN + (2 * Band).
  3. Plug in the values to calculate the uplink EARFCN.
  4. After inserting the variables and calculating the result, check your answer
