Analog signals representing sound and images are digitized in mobile phones, converted by analog-to-digital converters and transmitted as bit streams. All 5G wireless devices in the cell communicate via radio waves with the local antenna array and low-power automatic transceivers (transmitters and receivers) in the cell.
