Radio coverage &
line of sight,
computed on your GPU.
Waveshed is a free, browser-based tool for radio coverage maps and line-of-sight analysis. WebGPU does the work, parallel CPU workers fill in when it can’t, and the status line below shows every step.
The run on the map above.
These parameters are fed to the real engine, in your tab, the same pipeline that powers the simulator. Timings appear once the run completes, they are measured, not quoted.
COMPUTE BACKEND
Your GPU does the work.
The engine compiles the ITM model to WebGPU compute shaders and runs the coverage grid in parallel on your graphics hardware, off the main thread, so the page stays responsive. No GPU, or no WebGPU support? It falls back to parallel CPU workers automatically. Either way, every run reports which backend actually executed, never a guess.
- Primary
- WebGPU compute shaders, the coverage grid is evaluated in parallel on your GPU.
- Fallback
- Parallel CPU workers (WASM). Same engine, same results, just slower.
- Reporting
- The backend label on every run comes from the engine's own report, not a guess.
- Privacy
- All of it happens in your tab. Terrain comes down, nothing goes up.
