CO OZNACZA SŁOWO RADIO SPECTRUM
Widmo radiowe
Widmo radiowe odnosi się do części widma elektromagnetycznego odpowiadającego częstotliwościach radiowych - tzn. Częstotliwościach niższych niż około 300 GHz. Fale elektromagnetyczne w tym zakresie częstotliwości, zwane falami radiowymi, służą do komunikacji radiowej i różnych innych zastosowań, takich jak ogrzewanie. Generowanie fal radiowych jest ściśle regulowane przez rząd w większości krajów, koordynowane przez międzynarodowy organ normalizacyjny zwany Międzynarodową Unię Telekomunikacyjną. Różne części widma radiowego są rozdzielone na różne technologie i aplikacje transmisji radiowej. W niektórych przypadkach część widma radiowego jest sprzedawana lub licencjonowana dla operatorów prywatnych usług transmisji radiowej. Częstotliwość przydzielonych częstotliwości jest często określana przez ich przewidziane użycie.
Definicja słowa radio spectrum w słowniku
Definicja widma radiowego w słowniku to zakres częstotliwości elektromagnetycznych stosowanych w transmisji radiowej, leżących między 10 kiloherców a 300 000 megaherców.
