The engineer must perform a survey analysis on the potential RF impact of newer furniture materials. How must the survey be conducted?

Options:

A.

Perform a sweep analysis first to predict the signal strength across each point in a floor.

B.

Use a survey tool with the existing AP positions using building floor maps and material configuration.

C.

Measure upstream and downstream data rates based on the remodeling of the building.

D.

Evaluate the neighbor APs strength and density based on the rad* statistics information of each AP.
