It is remembered.
The output unit 1D includes information indicating the floor plan FP in the building acquired by the floor plan information acquisition unit 1A, information indicating the reception obstruction areas FA1, FA2, and FA3 acquired by the reception obstruction area information acquisition unit 1B, and reception recommendation. As shown in FIG. 6, which will be described later, based on the information indicating the recommended reception area RA acquired by the area information acquisition unit 1C and the information regarding the reception device RE (for example, the doorphone) acquired by the reception device information acquisition unit 1G. , The floor plan FP, the reception obstruction areas FA1, FA2, FA3, the recommended reception area RA, and the position of the reception device RE (doorphone) are superimposed and output.

FIG. 6 is a diagram showing still another example of the output result by the output unit 1D. In detail, FIG. 6 shows information indicating the floor plan FP acquired by the floor plan information acquisition unit 1A, information indicating the reception obstruction areas FA1, FA2, and FA3 acquired by the reception obstruction area information acquisition unit 1B, and a reception recommended area. Based on the information indicating the recommended reception area RA acquired by the information acquisition unit 1C and the information regarding the reception device RE (doorphone) acquired by the reception device information acquisition unit 1G, the floor plan FP and the reception obstruction areas FA1, FA2, An example is shown in which the FA3, the recommended reception area RA, and the position of the receiving device RE (doorphone) are superimposed and output.
In the example shown in FIG. 6, the receiving device RE (doorphone) is located outside the range of the recommended reception area RA. Therefore, the operator who consulted with the user of the building confirms the output result of the output unit 1D shown in FIG. 6, and the position of the receiving device RE (doorphone) is set to receive the radio wave transmitted by the transmitting device TE. It is easy to understand that it is not suitable and it is necessary to install an additional transmitting device (not shown) for the receiving device RE (doorphone) or to change the position of the transmitting device TE. Can be done.

In the example shown in FIG. 1, the communication environment information providing system 1 is provided with the receiving device information acquisition unit 1G, but in another example, even if the communication environment information providing system 1 is not provided with the receiving device information acquisition unit 1G. good.

In the example shown in FIG. 1, the determination unit 1H determines whether or not the reception obstruction areas FA1, FA2, and FA3 output by the output unit 1D overlap with the reception recommended area RA.
The determination result presenting unit 1I presents the determination result by the determination unit 1H as to whether or not the reception obstruction areas FA1, FA2, FA3 and the reception recommended area RA overlap.

FIG. 7 is a diagram showing an example of a determination result by the determination unit 1H as to whether or not the reception obstruction areas FA1, FA2, FA3 and the reception recommended area RA overlap.
In the example shown in FIG. 7, a part of the reception obstruction area FA1 and the reception recommended area RA overlap. Further, a part of the reception obstruction area FA2 and the reception recommended area RA overlap.
Therefore, as shown in FIG. 7, the determination result presenting unit 1I sets a portion (overlapping location) where a part of the reception obstruction area FA1 and the reception recommended area RA overlap from another location (non-overlapping location). Is also output as a judgment result (for example, display, printing, etc.) so as to be conspicuous (for example, processing such as hatching, highlighting, etc. is performed and output).
In another example, the communication environment information providing system 1 may not include the determination unit 1H and the determination result presentation unit 1I.

In another example, when the determination unit 1H determines that the reception obstruction areas FA1, FA2, FA3 and the reception recommendation area RA overlap, the output unit 1D or the determination result presentation unit 1I determines the reception recommendation area RA. The portion of the reception obstruction area excluding the portion overlapping with the reception interference areas FA1, FA2, and FA3 may be displayed as a true reception recommended area.
For example, the output unit 1D or the determination result presentation unit 1I displays the true reception recommended area in a two-dimensional display, a three-dimensional display, or the like. Alternatively, the output unit 1D or the determination result presentation unit 1I may display the true reception recommended area as a virtual object by using VR (virtual reality) technology.
For example, the output unit 1D or the determination result presentation unit 1I may present information indicating whether or not the reception is a true recommended reception area at each position in the real space of the building. Specifically, in this example, when a terminal device such as a smartphone is held over a position corresponding to a true reception recommended area in the space inside the building, the terminal device is recommended to receive true reception at the position of the terminal device. It receives information indicating that it is within the area, and displays on the display that the terminal device is located within the true recommended reception area. On the other hand, when the terminal device is held over a position that does not correspond to the true recommended reception area, the terminal device receives information indicating that the position of the terminal device is outside the true recommended reception area, and the terminal device is true. The display indicates that the device is located outside the recommended reception area.

In the example shown in FIG. 1, the recommended installation position calculation unit 1J is based on the floor plan FP output by the output unit 1D, the size and shape of the reception obstruction areas FA1, FA2, and FA3, and the size of the reception recommended area RA. , Calculate the recommended installation position of the transmission device TE (that is, simulate the installation position of the transmission device TE).
In the example shown in FIG. 7, the recommended installation position calculation unit 1J calculates a position other than the above-mentioned overlapping portion within the range of the reception recommended area RA as the recommended installation position of the transmission device TE.
In another example, the communication environment information providing system 1 may not include the recommended installation position calculation unit 1J.
