It is to be understood by those skilled in the art that the drawings are merely schematic representations of exemplary embodiments, and that the blocks or processes shown in the drawings are not necessarily required to practice the present disclosure and are, therefore, not intended to limit the scope of the present disclosure.
The terms involved in this disclosure are to be interpreted as follows:

ESSID is AN Extended Service Set Identifier (ESS), which is a single subnet consisting of two or more BSSs and is named as ESSID, which is generally the name of W L AN and is hereinafter referred to as SSID.
The inventor of the present disclosure finds that the current wireless local area network is composed of an AC and a plurality of APs, the AC is placed in a central machine room, the APs are more required to be deployed at various positions of an application scene in a coverage manner, each AP covers a certain area, and the plurality of APs form a large-scale wireless local area network to cover the whole application scene. Because the wireless local area network is formed by the joint work of a plurality of APs, certain requirements can be made on the positions of the APs. The point spacing of the AP cannot be too sparse, otherwise, wireless signals in some areas are weaker; the point spacing of the APs cannot be too dense, and due to limited wireless channel resources, the too dense point spacing causes interference between the APs by signals of the same or similar channels. Currently, point location planning is generally performed by a design house or an implementer for AP deployment, and the location of AP deployment is often marked on a drawing only according to the standard of the design house or the experience of the implementer (method one), or a general AP location is marked after a simple wireless signal test is performed (method two).
Both methods one and two are not optimal deployment methods. For the first method, because the AP performances of different manufacturers are different, and the thicknesses and materials of the shielding objects are different in different deployment environments, the coverage effects required to be achieved in different deployment scenes are different, and only labeling is performed on a drawing, so that the coverage effects required to be achieved really are difficult to meet.
For the second method, the wireless signal test can preliminarily know the application scenario, but for the complex application scenario, a plurality of test points need to be selected for testing, a large amount of manpower is needed, and the overall coverage effect is difficult to be intuitively known.
The wireless access point deployment method provided by the disclosure can provide a wireless environment engineering method, and aims to use an intuitive plan to show the coverage range of the AP signal, so that constructors can clearly know the current AP coverage effect, and the user experience of the whole wireless local area network is improved.
