Calculation Results

Frequency results will be displayed here after calculation.

Calculation Formula

Frequency (MHz) = 880 + (ARFCN × 5) MHz (for GSM 900 Band)

Frequency (MHz) = 925 + (ARFCN × 5) MHz (for GSM 1800 Band)

Frequency (MHz) = 1710 + (ARFCN × 5) MHz (for GSM 1900 Band)

Where:
ARFCN - Absolute Radio Frequency Channel Number
Frequency - The calculated radio frequency in MHz

GSM ARFCN to Frequency Converter Calculator Usage Guide

Learn how to use the GSM ARFCN to Frequency Converter calculator and its working principles

How to Use This Calculator

  1. Enter the ARFCN (Absolute Radio Frequency Channel Number) in the input field. ARFCN is a unique identifier for each radio frequency channel in GSM networks.
  2. Select the appropriate GSM band from the dropdown menu (Band 900, 1800, or 1900).
  3. Click the "Calculate" button to convert the ARFCN to the corresponding frequency.
  4. The results will display the band name, ARFCN value, and calculated frequency in MHz.

Understanding ARFCN

ARFCN (Absolute Radio Frequency Channel Number) is a system used in GSM to uniquely identify each radio frequency channel. It is a numerical value that correlates to a specific frequency band and channel number within that band.

Calculation Principles

The conversion from ARFCN to frequency follows these formulas based on the GSM band:

  • GSM 900 Band: Frequency (MHz) = 880 + (ARFCN × 5) MHz
  • GSM 1800 Band: Frequency (MHz) = 925 + (ARFCN × 5) MHz
  • GSM 1900 Band: Frequency (MHz) = 1710 + (ARFCN × 5) MHz

Practical Applications

This calculator is useful for:

  • Mobile network planning and optimization
  • Signal analysis and interference detection
  • Radio frequency engineering and design
  • Verifying frequency allocations in mobile communications
