Channel reference ranges
| Direction | Raster / condition | First channel | Step | Last channel |
|---|---|---|---|---|
| downlink | 100 kHz | 150600 | 20 | 156600 |
| downlink | 10 kHz (enhanced) | 150600 | 2 | 156600 |
| uplink | 100 kHz | 139600 | 20 | 145600 |
| uplink | 10 kHz (enhanced) | 139600 | 2 | 145600 |
Inclusive endpoints describe the reference grid. A usable carrier must also satisfy bandwidth, edge clearance, subcarrier spacing, synchronization raster, equipment and band-specific requirements. Enhanced rasters require corresponding support. Allocation edges are not automatically usable centre frequencies.
Worked downlink conversion
NR-ARFCN 153600 maps to 768 MHz.
F_REF = F_offset + ΔF_global × (N_REF − N_offset). Below 3000 MHz use (0 MHz, 5 kHz, 0); from 3000 MHz use (3000 MHz, 15 kHz, 600000); from 24250.08 MHz use (24250.08 MHz, 60 kHz, 2016667). The band raster is an additional constraint on that global grid.

Electrical length and propagation example
At 768 MHz, the free-space wavelength is 39.035 cm, the half-wave length is 19.518 cm and the quarter-wave length is 9.759 cm. Free-space path loss over 1 km is 90.155 dB.
These are reference calculations, not an antenna cut length or coverage prediction. Add feeder losses, antenna gains and propagation effects in the full link budget. A band match does not identify an operator or grant permission to transmit.
Sources and version
3GPP TS 38.104 V19.6.0 (Release 19, September 2026), tables 5.2-1, 5.2-2 and 5.4.2.3-1 through 5.4.2.3-4. Dataset 3gpp-rel19-2026-10-01; checked 2026-10-01. This page records that specification version rather than implying support in every device or country.
Bands with overlapping allocations
At least one corresponding uplink or downlink range overlaps; this does not imply equipment compatibility.
