| 摘要 |
The present invention discloses a proximity detection method and apparatus for a near field communication, which belongs to the field of communications technologies. The method includes: sending, by a first electronic device, a signal of a detection frame; determining whether a second electronic device capable of performing the near field communication exists according to a received response frame, wherein the detection frame includes at least two symbols modulated with different frequencies. In embodiments of the present invention, a signal of a detection frame which includes multiple symbols modulated with different frequencies is sent, so that a peer-to-peer electronic device existing within a communicatable range can be detected for communication in a case of that these modulation frequencies suffer an interference. |
