This tool calculates the distances between Wi-Fi access points in a Hamina design and shows each AP's nearest neighbours — useful for sanity-checking AP spacing, spotting APs placed too close together, and documenting a design.
To use it:
- Load your data. Either upload a Hamina JSON or OpenIntent JSON export, or switch to the Paste tab and paste the JSON directly. No data leaves your browser — everything is processed locally. (Use Load sample data if you just want to try it.)
- (Recommended) Add a floor plan. Upload a floor plan image to visualise AP placement. You can zoom and pan, and use Measure to check a distance between two points. (Optional) use Calibrate to set the image scale by clicking two points a known distance apart, if you need to correct the scale outside of the Hamina project.
- Map floor plans to floors. For multi-floor designs, each floor appears as a tab and you can assign the right floor plan image to each. With an OpenIntent import the floor plan metadata is matched to floors automatically; with a Hamina or manual import you may be asked which floor the data belongs to.
- Filter and review. Narrow results by floor, by AP name, or by a minimum / maximum distance. The Statistics panel summarises total pairs and the minimum, maximum, and average distances.
- Export. Save the distance results to CSV, Excel, or PDF, or copy them to the clipboard.
Distances are computed from the AP coordinates in your design file. Calibration aligns on-screen measurements to real-world distances when a floor plan's own scale isn't already known.
