� CW Measurement Data
Two ways of predicting along CW measurement path :• Using path loss matrix
(if existing)• Choice of a propagation
model to compute in real-time
Statistic reports (Averaged error and error standard
deviation per clutter class)Filter on distance, measured signal
level and angle/azimuth
Advanced filter on additional survey data
Filter per type(s) of clutter
Access to a precise analysis on the points to be
filtered for the calibration
