A la taula seg\u00fcent es mostren les assignacions de radiodifusi\u00f3 i d’aficionats, juntament amb el nom de banda amb que se solen con\u00e8ixer. No obstant aix\u00f2, no es tracta d’un equivalent exacte de longitud d’ona a freq\u00fc\u00e8ncia. Les bandes de radiodifusi\u00f3 estan marcades en taronja<\/span>. Entre les assignacions de radiodifusi\u00f3 es troben \u00e0mplies extensions de l’espectre que s’omplen de tota mena de enlla\u00e7os de comunicaci\u00f3 punt a punt, enviament mar a terra de sistemes telef\u00f2nics, enlla\u00e7os d’aviaci\u00f3 i comunicacions militars, ambaixades i comercials, i molt m\u00e9s. El tr\u00e0nsit militar i de les ambaixades sol estar xifrat per raons de seguretat. Hi ha molts modes de dades estranys i meravellosos, i de vegades s’escolten en els segments de radiodifusi\u00f3, ja sigui legalment o no. Tamb\u00e9 hi ha moltes senyals d’origen o prop\u00f2sit desconegut (com ara les estacions de nombres), que reenvien instruccions als espies a l’estranger?
