Abstract
A method and a system for near field communication of an electronic device are disclosed. The method comprises: communicating frequency points at which the two parties suffer from interference with a second electronic device through a scanning frame, wherein the scanning frame comprises at least two symbols modulated by using different frequencies; and determining a modulation manner according to the available frequency points in order to perform data transmission with the second electronic device. With the embodiment of the present invention, interference frequencies in the communication environment are detected by sending the scanning frame which comprises at least two symbols modulated by using different frequencies, and frequency points with smaller interference are selected for adaptation modulation data, thus the interference frequency points are shielded from data transmission, and external interference in the near field communication is avoid, and communication stability is improved, and communication quality is improved.
