5G NR ARFCN Calculator
Use this 5G NR ARFCN Calculator to quickly convert NR-ARFCN to frequency, frequency to NR-ARFCN, and explore FR1/FR2 band details with practical 5G NR band reference information.
5G NR ARFCN Calculator
Convert NR-ARFCN to frequency, convert frequency to NR-ARFCN, and quickly check FR1/FR2 band references with practical examples useful for 5G RAN, protocol testing, log analysis and RF planning.
ARFCN to Frequency
Enter NR-ARFCN from logs, SIB, scanner or test equipment and get the center frequency.
Frequency to ARFCN
Enter frequency in MHz and resolve the nearest valid NR-ARFCN on the global raster.
Band Detection
Automatically detects possible NR bands based on ARFCN or frequency overlap.
Learning Notes
Includes formula, raster details, examples and FR1/FR2 quick explanation.
Convert NR-ARFCN to Frequency
Use this when you see NR-ARFCN in logs, SIB information, cell configuration, drive-test tools, UE traces or gNodeB configuration.
What this means in network logs
Convert Frequency to NR-ARFCN
Use this when you know the frequency from RF planning, spectrum allocation, scanner output or lab configuration and want the corresponding NR-ARFCN.
NREF = NRef-Offs + (FREF − FRef-Offs) / ΔFGlobal
Frequency input must be aligned to the valid global raster spacing: 5 kHz, 15 kHz or 60 kHz depending on frequency range.

Formula Used in 5G NR ARFCN Calculation
FREF = FRef-Offs + ΔFGlobal × (NREF − NRef-Offs)Here, NREF is NR-ARFCN, FREF is reference frequency, FRef-Offs and NRef-Offs depend on the global frequency range, and ΔFGlobal is the global raster step.
