WiFi strife
Read OriginalThis article describes the author's experience troubleshooting erratic WiFi in a new flat by modeling signal propagation. Using Sketchup for layout, ImageJ for wall masks, and Matlab for ray-tracing, the author simulates WiFi hotspots and coldspots. The approach involves treating the router as emitting discrete rays that reflect off walls, with angle calculations from gradient images. The content is highly technical, covering computational methods like solving the Helmholtz equation and practical bricolage with available tools, making it relevant to IT/technology.
