Explanation
When you perform a floor calibration in a predictive wireless design tool (such as Cisco Prime Infrastructure or Ekahau), the tool uses a walk-through measurement to characterize how RF energy actually attenuates as it travels through that specific environment. The key attribute added is attenuation - the real-world signal loss caused by the building's specific materials (walls, floors, furnishings). Without calibration, the tool uses generic loss models; calibration replaces those estimates with measured attenuation values, significantly improving the accuracy of coverage predictions. TX power, multipath, and SNR are not the primary attributes added by a floor calibration.
