CDMA, Code Division Multiple Access, uses advanced mathematical techniques to allow multiple wireless devices to transmit simultaneously on the same frequency. Every device, such as a mobile phone, is assigned a unique mathematical signature. It applies this signature to the original signal and transmits the modified signal.
