Abstract
According to certain aspects, the present invention provides techniques to address G.fast and/or digital subscriber line (DSL) transmission at frequencies below and above 106 MHz in support of aggregate service rates well above 1 Gbps on short loops based on combining two independent first generation G.fast transceivers, each operating up to 106 MHz, into a single transceiver, capable of operating up to 212 MHz and achieving service rates of up to 2 Gbps. In these and other embodiments, a sub-band approach is used in which a total bandwidth is divided into two or more sub-bands, with communications for one or both of the first generation G.fast transceivers using one or both of the sub-bands, respectively.
