CE ÎNSEAMNĂ RADIO SPECTRUM ÎN ENGLEZĂ?
Spectrul radio
Spectrul radio se referă la partea din spectrul electromagnetic care corespunde frecvențelor radio - adică frecvențe mai mici decât aproximativ 300 GHz. Undele electromagnetice din această gamă de frecvențe, numite unde radio, sunt utilizate pentru comunicații radio și pentru alte aplicații, cum ar fi încălzirea. Generarea undelor radio este strict reglementată de guvern în majoritatea țărilor, coordonată de un organism internațional de standardizare numit Uniunea Internațională a Telecomunicațiilor. Diferite părți ale spectrului radio sunt alocate pentru diferite tehnologii și aplicații de transmisie radio. În unele cazuri, anumite părți ale spectrului de frecvențe radio sunt vândute sau licențiate operatorilor de servicii de radiodifuziune privată. Rangurile de frecvențe alocate sunt deseori menționate prin utilizarea lor provizorie.
Definiția radio spectrum în dicționarul Engleză
Definiția spectrului de frecvențe radio în dicționar este gama frecvențelor electromagnetice utilizate în transmisia radio, situată între 10 kilohertzi și 300 000 megahertzi.
