LTE Band 40 frequencies and EARFCN ranges
LTE Band 40 is TDD (Terrestrial): downlink 2300–2400 MHz, uplink 2300–2400 MHz. View exact EARFCN ranges, rasters and specification notes.
- downlink (shared TDD range)
- 2300–2400 MHz
- uplink (shared TDD range)
- 2300–2400 MHz
Channel reference ranges
| Direction | Raster / condition | First channel | Step | Last channel |
|---|---|---|---|---|
| downlink | 100 kHz | 38650 | 1 | 39649 |
| uplink | 100 kHz | 38650 | 1 | 39649 |
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 39149 maps to 2349.9 MHz.
F = 2300 + 0.1 × (39149 − 38650) = 2349.9 MHz. The offset and lower reference frequency belong to this band and direction.

Electrical length and propagation example
At 2349.9 MHz, the free-space wavelength is 12.758 cm, the half-wave length is 6.379 cm and the quarter-wave length is 3.189 cm. Free-space path loss over 1 km is 99.869 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.
