Zusammenfassung:A modem transmits data between a computer and a telephone line. The modem features a base unit which receives a data signal from the telephone line and which transmits the data signal over a wireless link. A device receives the data signal over the wireless link and outputs an analog data signal that corresponds to the data signal. A modem card receives the analog data signal from the device, digitizes the analog data signal to produce a digital signal, demodulates the digital signal, and provides an output digital data signal to the computer.
