Embodiment

[0025] Such as Figure 1 to Figure 4 As shown, the method of communicating through data embedded in the probe request frame in an unassociated WIFI environment is mainly to solve the problem in the prior art that devices in the same wireless local area network cannot communicate without authentication association question. The method not only supports single-point to single-point, single-point to multi-point, multi-point to single-point, multi-point to multi-point one-way communication, but can adapt to various complex wireless network communication environments. The method is designed based on the 802.11 standard, and can be extended and compatible with the 802.11 protocol family; meanwhile, it can also support AD-Hoc networks, BSS networks, and ESS networks. Specifically, this method is implemented on the basis of a sending end and a receiving end in the same WIFI environment, wherein the sending end is connected to the WIFI; in a commonly used AP-STA network topology, usua...

Abstract

The invention discloses a method for communication through detection request frame embedded data under the unrelated WIFI environment. The system according to the method comprises a transmitting end and a receiving end which are arranged in the same WIFI environment. The transmitting end inserts an information unit unrelated to a transmission protocol in a detection request frame, embeds data under communication in the information unit, starts the detection request frame for transmission and periodically broadcasts the detection request frame in all the channels. The receiving end works in a monitoring mode, periodically monitors and captures the detection request frame in the current channel and extracts the corresponding data so that data communication is realized. The information unit without influencing the transmission protocol is ingeniously inserted in the detection request frame for data embedding so that transmission of SSID and corresponding passwords and other data under the unrelated condition is realized, automatic accessing of terminals within a wireless local area network is realized, the problems in the prior art that equipment requires direct correlation for communication can be effectively solved and the method is particularly suitable for intelligent household internal wireless networking.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for communicating by detecting data embedded in a request frame in an unrelated WIFI environment. Background technique [0002] With the continuous rise of the Internet and the increasingly prominent mobile demand, the demand for wireless interconnection is also becoming stronger. Among the existing wireless communication technologies, the bluetooth communication technology has a small coverage area, and the infrared communication technology is greatly affected by the environment, and the effect of penetrating walls is not ideal. Due to its wide application, WIFI communication technology is gradually accepted by enterprises and families. However, the traditional standards-based IEEE802.11 defines the wireless network specification: one wireless point acts as an AP (Access Point) mode, and other wireless points act as a STA (Station) mode. After the STA as...
