5G NR ARFCN to Frequency

Convert channel reference numbers using the 3GPP global NR raster and each band's published channel grid.

Frequency (MHz)

3450

3300–3800 MHz

Matches the selected downlink reference grid. Carrier bandwidth and band-specific restrictions still apply.

Global grid and band raster

F_REF = F_offset + ΔF_global × (N_REF − N_offset). The global raster is 5 kHz below 3000 MHz, 15 kHz from NR-ARFCN 600000, and 60 kHz from NR-ARFCN 2016667 (24250.08 MHz).

For n78, NR-ARFCN 630000 gives 3000 + 0.015 × (630000 − 600000) = 3450 MHz. NR-ARFCN 620000 is 3300 MHz.

A band can use only selected entries on that grid. Choose the direction and raster; off-grid frequencies are rejected rather than rounded. This checks the channel reference grid, not a full radio configuration: bandwidth, guard bands, SCS, synchronization and band-specific channel restrictions still apply. See the source-linked NR band directory.
