Abstract

The invention provides a WIFI data transmitting method. The method comprises the steps that a sending end processes original information needing to be transmitted into binary form data to be sent; the sending end adds the data to be sent to a multicast IP address; the sending end maps the multicast IP address into a corresponding multicast MAC address; the sending end sends out a multicast data package comprising the multicast MAC address in a circulating mode; a receiving end scans a WIFI channel in a circulating mode so as to detect the multicast data package; the receiving end obtains the multicast MAC address of the multicast data package when detecting the multicast data package; the receiving end extracts the binary form data, to be sent, of the multicast MAC address; the receiving end restores the data to be sent to the original information needing to be transmitted. According to the WIFI data transmitting method, the data to be transmitted are set into the multicast address, the receiving end further obtains the original information needing to be transmitted through the multicast address, and in this way the information can be transmitted in a WIFI network without decrypting the WIFI. The invention further relates to a WIFI data transmitting system and a related method thereof.
