I think the data, video, and communications for a cable such as coaxial cables fall in the same frequency range as RF or radio frequencies. adc, analog to digital converter used would count the bits per second that the cables transmit into the cable system. So if you were on a wireless, the RF would be the same as if you were actually listening it on a AM or FM station. Such would be your cell phone Android smart phone and contacting a radio signal from it. Same frequencies. You mean a turner that detects signals from many different frequencies at the receiver's box or adc, analog to digital converter box in your home.
