- The estimate uses log-distance loss (n=2.5) plus wall and floor attenuation, with a stated typical error of ±8 dB.
Field notes
The workspace opens with a 16 × 12 m example plan, which users can resize or trace over an uploaded floor-plan image after setting its scale. Wall materials have separate attenuation values for each of the three bands, and the guide also explains signal-strength thresholds in dBm. A keyboard-shortcut guide and project JSON import/export support editing and saving without an account.
