EMF Spectrum Explorer
Interactive radio frequency allocation chart with
nearly 50 national tables, plus the
FCC (United States),
CEPT ECA, and
ITU Regions 1–3. Compare countries, scroll a log-scale
spectrum, filter by radio service, search frequencies, and inspect band
and channel details.
This is an educational visualization inspired by the NTIA
wall chart. It is not an official regulatory source — always cross-check the
relevant national administration, the FCC table, or the ITU Radio Regulations.
