Explanation:
If the provided RF models do not sufficiently characterize the floor layout, you can create a calibration model that is applied to the floor and better represents the attenuation characteristics of that floor. The calibration models are used as RF overlays with measured RF signal characteristics that can be applied to different floor areas. This enables the Cisco WLAN solution installation team to lay out one floor in a multi- floor area, use the RF calibration tool to measure, save the RF characteristics of that floor as a new calibration model, and apply that calibration model to all the other floors with the same physical layout.
You can collect data for a calibration using one of two methods:
Point mode data collection-Calibration points are selected and their coverage area is calculated one

location at a time.
Linear mode data collection-A series of linear paths are selected and then calculated as you traverse the path. This approach is generally faster than the point mode data collection. You can also employ point mode data collection to augment data collection for locations missed by the linear paths.
