Channel reference ranges
| Direction | Raster / condition | First channel | Step | Last channel |
|---|---|---|---|---|
| downlink | 100 kHz | 9040 | 1 | 9209 |
| uplink | 100 kHz | 27040 | 1 | 27209 |
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
EARFCN 9124 maps to 860.4 MHz.
F = 852 + 0.1 × (9124 − 9040) = 860.4 MHz. The offset and lower reference frequency belong to this band and direction.

Electrical length and propagation example
At 860.4 MHz, the free-space wavelength is 34.843 cm, the half-wave length is 17.422 cm and the quarter-wave length is 8.711 cm. Free-space path loss over 1 km is 91.142 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 36.101 V19.6.0 (Release 19, August 2026), tables 5.5-1, 5.5H-1, 5.7.3-1 and 5.7.3H-1. 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.
