Use of radio frequency bands of the electromagnetic spectrum is regulated by governments in most countries, in a Spectrum management process known as frequency allocation or spectrum allocation. Radio propagation does not stop at national boundaries.
frequency allocationとは意味:周波数分配{しゅうは すう ぶんぱい} frequency allocation meaning:[Electronics] 1. The assignment of frequencies to radio and allied services by the licensing authority (in the United States, the Federal Communications Commission). 2. A specific assignment of a fre...frequency allocation перевод:распределенияе частот
