A method of using customer premise cable modem equipment to generate a signal that can be used for leakage detection. Various signal types are described which are usable for the purposes of leakage detection.

Leakage detection for cable TV systems with upstream signals above 118 MHz

Signal ingress at an installations site forming a part of a broadband communication system is quantitatively evaluated for resistance to signal ingress using a computed ambient broadcast signal level based on a known location and effective radiated power of one or more transmitters. Anomalies due to signal path obstruction and/or multi-path reception are compensated by performing computations for a plurality of broadcast transmitters located in different directions from the installation site.

Shielding integrity testing for cable drop

Issuance of work orders in response to monitoring signal egress from shielding integrity flaws in a cable communication system by detecting received signal strength from a mobile receiver only during rising trends in received signal strength when the mobile receiver is in motion and tracking the maximum received signal strength peak during each rising trend. Rising trends are detected by computing two rolling averages of received signal strength sample of different lengths and offset from each other and applying a threshold to the difference between the rolling averages to provide hysteresis in switching between rising and falling trend detection. Reported peaks are then compared by proximity to each other and their circle of influence determined in accordance with respective signal strengths to determine if newly reported peaks are duplicates of previously reported peaks and duplicate reported peaks are removed or discarded.
