Embodiment Construction

[0024] This specific embodiment discloses a method for capturing the MAC address of a WIFI terminal, such as figure 1 shown, including the following steps:

[0025] S1: Set the wireless device to work in passive mode;

[0026] S2: Switch the working channel regularly, for example, the switching period can be set to 300 milliseconds;

[0027] S3: determine whether there is a WIFI terminal connected to the AP: if yes, go to step S4; otherwise, return to step S2;

[0028] S4: Switch the wireless device to work in the active mode and no longer switch the working channel;

[0029] S5: Construct a NULL frame, set the source MAC address for the NULL frame, the destination MAC address of the NULL frame is the MAC address of the WIFI terminal, and use a list to record the correspondence between the source MAC address of the NULL frame and the MAC address of the WIFI terminal, Then periodically send NULL frames to the WIFI terminal; for example, the period for sending NULL frames can...

Abstract

The invention discloses a MAC address capturing method of a WIFI terminal, which includes six steps. After the WIFI terminal is connected to an AP, the wireless device sends a NULL frame to the WIFI terminal, so that the WIFI terminal will reply an ACK frame, thereby increasing the wireless The amount of communication data between the device and the WIFI terminal is convenient to track the state change of the WIFI terminal in real time, especially the position change, so as to realize the efficient capture of the MAC address of the WIFI terminal.

Description

technical field [0001] The present invention relates to a MAC address capture method, in particular to a MAC address capture method of a WIFI terminal. Background technique [0002] With the rapid development of the Internet, WIFI urban hotspots and self-built wireless networks have been widely popularized in major cities. There are a large number of wireless WIFI available in public places (such as hotels, stores and other entertainment and leisure places), universities and residential areas. for terminal access. With the development of wireless WIFI network, the demand of national security management unit to supervise WIFI network is also increasing day by day. MAC (Media Access Control) address, also known as MAC address and hardware address, is the unique identity used to identify network devices. By capturing the MAC address of WIFI terminals, it can be used to collect, locate and control WIFI terminals. [0003] The application number in the prior art is 201310698106...
