Abstract :
The indoor PLC (Power Line Communications) and VDSL2 (Very high bit-rate Digital Subscriber Line) technologies share the same frequency band up to 30 MHz. Behind the VDSL2 access network, the power line network is envisaged to be used like an home network in order to transit TV flows from the VDSL2 modem to the set-top-box. In many customer premises, power line cables are nearby telephone cables and consequently unwanted couplings could occur generating hence VDSL2 QoS decrease. This paper describes an experimental study of PLC coupling effect on VDSL2. Two approaches are followed in order to highlight this coupling effect. The first one consists in studying the PLC coupling effect on VDSL2 relying in different coexistence scenarios made in laboratory. The second one is based on field test measurements into several houses: coupling noises are measured on phone plugs when PLC signals are transmitted in sockets.
