PROBLEM TO BE SOLVED: To provide an information processing system improved in usefulness. SOLUTION: An information processing terminal system includes an information processing terminal 4 and a transmission/reception device 3. The transmission/reception device 3 is mounted on the information processing terminal 4. The transmission/reception device 3 demodulates a reception modulation wave signal from a network, converts the demodulated reception modulation wave signal into a reception analog baseband signal, and converts the converted reception analog baseband signal into a reception digital baseband signal by synchronizing with clock. The information processing terminal 4 converts the converted reception digital baseband signal into reception data by synchronizing with clock and converts transmission data into a transmission digital baseband signal by synchronizing with clock. The transmission/reception device 3 converts the converted transmission digital baseband signal into a transmission analog baseband signal by synchronizing with clock, converts the converted transmission analog baseband signal into a transmission modulation wave signal, and transmits the converted transmission modulation wave signal to the network.
