Suddivisione IARU delle bande a microonde

Nota la ripartizione delle frequenze, stabilita da ogni Paese con una propria legislazione, per conoscere il tipo di emissione e la banda occupata utilizzabile la IARU, l'Unione Internazionale dei Radio Amatori, suddivide a sua volta ogni banda di frequenze.

Questa suddivisione è subordinata alla concessione delle frequenze; quindi particolari modalità come potenza massima, limiti di frequenza o statuto devono essere seguiti secondo la normativa locale vigente.
