λ = 299,792,458 / f_Hz. Free-space values; antenna end effects and propagation velocity change physical lengths.
Worked channel conversion
F_DL = 1805 + 0.1 × (1575 − 1200) = 1842.5 MHz. The paired uplink reference is 1747.5 MHz at EARFCN 19575.
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.
