Study of the coexistence of VDSL2 and PLC by analysing the coupling between power line and telecommunications cable in the home network

PLC (Power Line Communications) and VDSL2 (Very high bit-rate Digital Subscriber Line) allow high bit-rate transmissions, through power line and copper pair respectively, but both technologies use the same frequency band. Consequently, these technologies could have to coexist in a home network inside the customer premises. This paper describes a theoretical analysis of the electromagnetic coupling between PLC and VDSL2 links. The effects of different parameters such as copper pair characteristics distance between the power line and the copper pair are presented.
