GSM ARFCN Calculator: Convert ARFCN to Frequency

This tool helps you convert GSM ARFCN (Absolute Radio Frequency Channel Number) to its corresponding uplink (UL) and downlink (DL) frequencies. It provides the output frequencies in MHz.

Example:

• Input: GSM ARFCN = 100
• Outputs:
  • GSM Uplink Frequency = 910 MHz
  • GSM Downlink Frequency = 955 MHz

GSM ARFCN Calculator Formula

The following equation is used to convert ARFCN to frequency:

As illustrated above, ARFCN is a number that represents a GSM downlink-uplink frequency pair.

Understanding ARFCN

GSM ARFCN stands for Absolute Radio Frequency Channel Number. The concept of ARFCN simplifies the RF frequency planning and maintenance processes within a GSM system. Essentially, it provides a numerical index to easily identify a specific frequency channel.
