Abstract

A radio wave environment analysis device includes: a processor which acquires radio wave environment data obtained by associating, with position information within an area including a plurality of observation points, an analysis result based on an analysis of the radio wave environment corresponding to a radio wave transmitted from at least one wireless transmitter disposed within the area; and a memory configured to store the radio wave environment data. The processor is configured to select a region that is a part of the area, extract partial radio wave environment data corresponding to the selected part, and output predetermined radio wave environment distribution data based on the extracted partial radio wave environment data on a display device.

First claim

The invention claimed is:

1. A radio wave environment display device comprising:
a processor configured to acquire radio wave environment data obtained by associating, with position information within an area comprising a plurality of observation points, an analysis result based on an analysis of a radio wave environment corresponding to a radio wave transmitted from at least one wireless transmitter arranged within the area; and
a memory configured to store the radio wave environment data,
wherein the processor is configured to:
select a region that is a part of the area;
extract partial radio wave environment data corresponding to the selected part; and
output predetermined radio wave environment distribution data based on the extracted partial radio wave environment data on a display device.

2. The radio wave environment display device according to claim 1 further comprising:
an operation input unit configured to receive an operation of a user,
wherein in response to a designation operation of the user designating a part of the area, the processor is configured to extract partial radio wave environment data corresponding to the designated part.

3. The radio wave environment display device according to claim 1 ,
wherein the part of the area comprises a point where the wireless transmitter is arranged.

4. The radio wave environment display device according to claim 3
wherein the processor is configured to:
analyze, based on the partial radio wave environment data extracted in a predetermined period, data which indicates a status of a wireless terminal connectable to the wireless transmitter and corresponds to the part in the predetermined period; and
output an analysis result to the display device.

5. The radio wave environment display device according to claim 1 ,
wherein the part of the area comprises a flow line of one or more persons passing through a point where the wireless transmitter is arranged or a position near the point.

6. The radio wave environment display device according to claim 1 ,
wherein the processor is configured to:
divide the partial radio wave environment data into partial radio wave environment data for each of a plurality of sub-regions obtained by dividing the part such that each of the plurality of sub-regions has a predetermined area; and
display the partial radio wave environment data corresponding to the sub-region with a sphere having an area smaller than the predetermined area.

7. The radio wave environment display device according to claim 1 ,
wherein the processor is configured to:
divide the partial radio wave environment data into partial radio wave environment data for each of a plurality of sub-regions obtained by dividing the part such that each of the plurality of sub-regions has a predetermined area; and
display the partial radio wave environment data corresponding to the sub-region with a cone having an area smaller than the predetermined area.

8. A radio wave environment display method to be performed in a radio wave environment display device, the radio wave environment display method comprising:
acquiring radio wave environment data obtained by associating, with position information within an area comprising a plurality of observation points, an analysis result based on an analysis of a radio wave environment corresponding to a radio wave transmitted from at least one wireless transmitter arranged within the area;
storing the radio wave environment data into a memory;
selecting a region that is a part of the area, and extracting partial radio wave environment data corresponding to the selected part; and
outputting predetermined radio wave environment distribution data based on the extracted partial radio wave environment data on a display device.
