Step 203: and calculating the signal propagation environment data of the area to be covered according to the indoor structure.

The signal propagation environment data is signal propagation gain data between any two regions, and the received signal strength at one region when a signal of a specific strength is transmitted from the other region can be calculated from the signal propagation environment data.

Furthermore, in the indoor building structure shape data taking pixel points as units, the pixel points are the highest-precision units and depend on the precision of the original map data; for example, most raw map data can be several centimeters or tens of centimeters in geographic size, whereas for large buildings, resolution to the accuracy of several centimeters or tens of centimeters results in a huge amount of map data, increasing processing complexity. Moreover, for indoor coverage design, the position precision of design and construction is usually meters, and the precision of a few centimeters or tens of centimeters is basically beneficial to improving the coverage performance in practical application; for example, moving the position of a wireless signal transmitting/receiving point by several centimeters or tens of centimeters does not significantly change the signal field intensity distribution, and therefore, in the embodiment of the present invention, the indoor building structure shape data in units of pixel points is rasterized, and the signal propagation environment data is calculated in units of grids. Therefore, the present step can be realized by the following steps (1) to (3), including:

(1): and dividing the area to be covered into a plurality of subareas to be covered.

According to the area of the area to be covered, the area to be covered is divided into a plurality of sub-areas to be covered, and a plurality of geographically adjacent pixel points in each sub-area to be covered in the plurality of sub-areas to be covered.

The area of each to-be-covered sub-region is equal, the shape of each to-be-covered sub-region can be a rectangular grid, the area of each to-be-covered sub-region can be set and changed according to the geographic resolution of each to-be-covered region, and the area of each to-be-covered sub-region is not specifically limited in the embodiment of the invention; and the larger the area of the sub-area to be covered, the lower the geographic resolution after rasterization; conversely, the smaller the area of the sub-area to be covered, the higher the geographic resolution after rasterization.

(2): and calculating the signal propagation environment data of each subarea to be covered according to the structure of each subarea to be covered in the plurality of subareas to be covered.

This step can be realized by the following steps (2-1) to (2-3), including:

(2-2): and calculating the attribute information of the first to-be-covered subarea according to the attribute information of the pixel points in the first to-be-covered subarea.

Because the first to-be-covered sub-region is a set of a plurality of pixel points, the attribute information of the first to-be-covered sub-region depends on the attribute information of the plurality of pixel points included in the first to-be-covered sub-region, and the calculation method of the attribute information of the first to-be-covered sub-region needs to reflect the physical significance of the attribute information, for example, when the attribute information of the first to-be-covered sub-region is penetration loss, the sum of the penetration losses of the pixel points included in the first to-be-covered sub-region is calculated, and the sum of the penetration losses is used as the penetration loss of the; for another example, when the attribute information of the first to-be-covered sub-region is the angle of the reflecting surface, calculating the average value of the angles of the reflecting surface of the pixel points included in the first to-be-covered sub-region, and taking the average value of the angles of the reflecting surface as the angle of the emitting surface of the first to-be-covered sub-region.

Therefore, the step can be:

and acquiring a calculation rule, and calculating the attribute information of the pixel points included in the first to-be-covered subarea according to the calculation rule and the attribute information of the pixel points included in the first to-be-covered subarea.

The calculation rules may be summation, averaging, selecting a maximum value, selecting a minimum value, calculating according to weights, etc.

(2-3): and calculating signal propagation environment data of the first to-be-covered sub-region according to the attribute information of the first to-be-covered sub-region and the indoor propagation model.

The terminal stores the corresponding relation of attribute information, an indoor propagation model and signal propagation environment data in advance; in this step, the terminal obtains the signal propagation environment data of the first to-be-covered sub-region from the corresponding relationship among the attribute information, the indoor propagation model and the signal propagation environment data according to the attribute information and the indoor propagation model of the first to-be-covered sub-region.

And (3) calculating the signal propagation environment data of each sub-area to be covered according to the steps (2-1) to (2-3) for each sub-area to be covered to obtain the signal propagation environment data of each sub-area to be covered, and executing the step (3).

For example, to ensure the tidiness of the leader office, the leader office is an area to be covered without placing a wireless signal transceiver in the leader office.

In this step, for convenience of description, any one of the at least one area block is referred to as a first area block, and it is determined whether a wireless signal transmitting/receiving point can be placed in the first area block.
