When preparing a floor plan graphic for use in predictive and manual site surveying, what calibration
method will lead to the most accurate and reliable RF data?

A.
Use the known size of a small object, such as a ceiling tile, and use a single instance of this object (e.g.
a single ceiling tile) to scale the floor plan.

B.
Measure the width of an actual office doorway with a tape measure and use this value to calibrate
against a doorway graphic.

C.
Use the longest available measurement (like a straight exterior wall) to calibrate the graphic’s scale.

D.
Calibrate the ceiling height of the floor plan first, then the survey software should be able to autocalibrate the X and Y planes of the graphic.

E.
With properly formatted .bmp and .png graphics, the site survey software should be able to extract the
scale directly from the graphic data during import.
