A method to compute open area test site uncertainty using ANSI C63.4 normalized site attenuation measurement data

ANSI C63.4 provides a criterion for an ideal open area test site (OATS) as normalized site attenuation (NSA) verses frequency. Using these factors, a level of uncertainty with a stated confidence level can be calculated for a given set of measurements. This level of uncertainty can be used as a measure of the quality of a test site and provides a convenient method to assess different sites.
