Band-specific conditions
- LTE-based 5G terrestrial broadcast: supplemental downlink-only (SDO), not an NR band.
Channel reference ranges
| Direction | Raster / condition | First channel | Step | Last channel |
|---|---|---|---|---|
| downlink | 100 kHz | 71106 | 1 | 73385 |
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 72245 maps to 583.9 MHz.
F = 470 + 0.1 × (72245 − 71106) = 583.9 MHz. The offset and lower reference frequency belong to this band and direction.

Electrical length and propagation example
At 583.9 MHz, the free-space wavelength is 51.343 cm, the half-wave length is 25.672 cm and the quarter-wave length is 12.836 cm. Free-space path loss over 1 km is 87.775 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

Bands with overlapping allocations
At least one corresponding uplink or downlink range overlaps; this does not imply equipment compatibility.
