Sentences with phrase «radio emission»
"Radio emission" refers to the signals or waves transmitted by a radio, which carry sound or data to be received and heard on another device known as a radio receiver. It is how radio stations, satellites, or other devices communicate information wirelessly through the air. Full definition
