space. VisualRF will calculate an attenuation grid for the entire map including white space.
Reducing the white space on a floor plan will increase location accuracy and decrease the load
an on the server. A good rule of thumb would be about ½ inch white space, is possible, on all
sides.

Description
The VisualRF service dissects each floor plan into a grid consisting
of cells specified in this setting. The Core Thread service calculates
the path loss for every radio to every cell on the floor plan.
By default the importation wizard allocates 2,500 grid cells to each
site based on dimensions. If you have a site that is 250 ft. by 100 ft,
the Floor Plan importation wizard would calculate the grid cell size at
10 feet. 250 ft. x 100 ft. = 25,000 ft. 25,000 ft. / 2,500 ft. = 10 ft.
Note: Decreasing the grid cell size will increase accuracy, but it also
increase CPU consumption by the floor caching threads and the
location caching threads. Check the System
to ensure your server is functioning properly when you make a
change to this setting.
