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.
