Over the past decades, broadband technologies for access networks and home networking have seen an increasing level
of improvements to meet consumers expectations in speed and services.The demand for higher bit rate data services from customer side is promoted by high-speed Internet access and many
forthcoming innovative services as UHD video streaming. This demand become possible with the deployment of DSL
technology as well as the extension to DSL vectoring and bonding.Recent advances in power line communications (PLT) have made it popular for in-home networking. This makes PLT a
source of interference for digital subscriber line (DSL) networks within the home environment.The present document proposes interference mitigation solutions that allow the coexistence of in-home PLT and DSL
networks.In addition, the present document proposes two interference mitigation solutions that enhance the coexistence of inhome
PLT and DSL networks.The interactions between a Digital Subscriber Line (DSL) access network and Home Networks based on Powerline
Telecommunication (PLT) have been reported during past years as PLT modems are widely used for IPTV distribution
in a home.PLT networks and DSL networks use some of the same frequencies in the unlicensed band from 2 - 88 MHz. PLT
devices and DSL devices may often be placed in relative proximity to each other and there are concerns that this could
present interference.
