| Zusammenfassung: | A communication system for communicating utility data from a utility distribution network comprises a transmitter for transmitting the utility data. The transmitter comprises a processor that modulates the utility data into a plurality of carrier frequencies. A modulator is connected to the processor and receives the modulated utility data. The modulator modulates the modulated utility data in the AM frequency band forming multi-tone modulated data wherein the transmitter transmits the multi-tone modulated data/transmitted information in the AM frequency band. The communication system also comprises a receiver that receives the transmitted information. The receiver comprises a demodulator that receives the transmitted information and demodulates the transmitted information into a received signal. A processor is connected to the demodulator and receives the demodulated information. |
