Shielding Effectiveness of In-Home Cable TV Wiring and Splitters
The purpose of this testing was to characterize the ability of typical in-home CATV cable wiring, connectors and terminations to protect cable TV signals against unwanted interference from fields radiated by consumer TV White Space (TVWS) devices. This protection is called Shielding Effectiveness (SE). Devices attached to this cabling system will exhibit interference commonly referred to as Direct Pickup or DPU interference. DPU interference is directly related to the shielding effectiveness of the cable, connectors and shielding performance of the tuner of the device attached when in the presence of other radiating devices such as the proposed TV White Space (TVWS) devices.
