λ = 299,792,458 / f_Hz. Free-space values; antenna end effects and propagation velocity change physical lengths.

Worked channel conversion

F_REF = 3000 + 0.015 × (630000 − 600000) = 3450 MHz. For comparison, NR-ARFCN 620000 is 3300 MHz.

Propagation example

At 3450 MHz over 1 km, free-space path loss is 103.204 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.
