Actix Pilot Pollution Analysis

Pilot PollutionActix scripts for segments analysis have been enhanced with with the addition of pilot pollution arrays: Number of pilots seen in every bin Number pilot polluters SC of 1st order pilot pollution SC of 2nd order pilot pollution SC of 3rd order pilot pollution

Pilot pollution is defined as cases of poor dominance, where too many pilots are present and can result in: Reduced capacity, Excessive soft handoff events

A pilot is considered to be a polluter if it is within 8 dB of best server when the active set is >=3Active set size is estimated from scanner data by using network SHO thresholds.
