  • Apparatus and method for data communication using radio frequency
    Patent number: 8605773
    Abstract: A data communication apparatus using a radio frequency and a data processing method thereof are provided. A first communication apparatus frequency shift keying and phase shift keying modulates and transmits data from a service server to a radio frequency band. A second communication apparatus modulates, demodulates, and outputs the data. The data communication apparatus using a radio frequency, includes: a data modulation module frequency shift keying and phase shift keying modulates data to a radio frequency band to generate a modulated data signal; and a data transmission module transmitting the modulated data to another communication apparatus.
