1842.5 MHz frequency reference
1842.5 MHz is a downlink reference frequency in LTE Band 3 at EARFCN 1575. It also lies in NR n3 downlink at NR-ARFCN 368500.
| Frequency | 1842.5 MHz / 1.8425 GHz |
|---|---|
| LTE match | Band 3 / FDD / downlink |
| LTE EARFCN | 1575 |
| NR match | n3 / FDD / downlink |
| NR-ARFCN | 368500 |
| Paired LTE uplink | 1747.5 MHz / EARFCN 19575 |
Electrical lengths at 1842.5 MHz
- Wavelength
- 16.271 cm
- Half wave
- 8.135 cm
- Quarter wave
- 4.068 cm
λ = 299,792,458 / f_Hz. Free-space values; antenna end effects and propagation velocity change physical lengths.
Worked channel conversion
LTE N = 1200 + (1842.5 − 1805)/0.1 = 1575. NR N_REF = 1842.5/0.005 = 368500.
Propagation example
At 1842.5 MHz over 1 km, free-space path loss is 97.756 dB. This assumes far-field, unobstructed propagation. Antenna gain, cable loss, obstructions and fading belong in the full link budget.
Assumptions and limits
These are channel reference points. A complete radio configuration also needs supported bandwidth, guard bands, subcarrier spacing and device capabilities. Band membership does not show operator use or permission to transmit. See the LTE and NR directories for the full versioned band catalogue.
