WiFi Heatmap provides predicted signal coverage based on a simplified COST-231 multi-wall propagation model. Predictions typically fall within ±6–10 dB of measured reality but real environments may differ due to factors not modeled (3D effects, metal furniture, multi-floor leakage, capacity contention). Validate placements with a real-world survey before commercial install.
The service is provided "as is" without warranty of any kind. We are not liable for installation decisions made based on predictions from this tool.
Don't abuse the service: no automated scraping, no attempts to bypass rate limits, no resale of API access. Free tier limits are enforced; circumventing them is a breach of these terms.
