1. A method for simultaneous transmission of upstream and downstream signals in a same frequency band, the method comprising:
receiving at a position following a Full Duplex (FDX) node in the downstream direction, a downstream analog signal from the FDX node and an upstream analog signal in the same frequency band;
separating and separately amplifying the downstream analog signal and the upstream analog signal;
reducing crosstalk between the upstream and downstream signals so as to isolate the separated downstream analog signal and the separated upstream analog signal from one another;
sending, the amplified downstream analog signal downstream; and
sending the amplified upstream analog signal towards a full duplex node.
