Deriving broadband communication system service area for signal leakage detection

Abstract

An improved, adaptive and uniformly applicable estimation of the percentage or fraction of a broadband communication system (BCS) plant that is monitored for signal egress during a given period of time is provided by generating and collecting polygons along all possible routes traversed by DOS service vehicles within a service area, preferably by comparison with a roadway map, to define the service area with improved accuracy. The number of polygons generated and collected is then limited by the number of polygons in which DCS service vehicles have been reported in a given period of time or inspection interval. The limited number of polygons is then divided by the number of polygons generated and collected to determine a fraction or percentage of the BCS system which has been monitored during the given time period and can be used in a computation of a cumulative leakage index (CLI) value.
