Shared Pathloss Matrices Stored in a shared folder on the server farm (shared driver) Batch/Administrator calculation (transparent to the user)
Performed incrementally on a daily basis (overnight) One public pathloss matrix folder per market per technology - for all users
E.g. one folder for North Texas GSM one folder for North Texas TDMA one folder for North Texas UMTS
Accessible as read-only mode (users cannot write in the shared pathloss matrix folder)
Private Pathloss matrices Stored in a private folder on the server farm (user folder on H: drive) Private pathloss matrices calculated only for sites with invalid or missing
shared pathloss matrices

DO NOT EMBED GEO DATA! Make sure NOT to embed geo data in your Atoll project
Embedding geo data would increase significantly the size of your Atoll project and can lead to numerous memory issues
In case, you did embed geo data: Delete the embedded file Re-import the geo data (as previously explained)

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
