Devices, systems and methods for transmitting data compliant with home networking standard over twisted pair cables

A system for transmitting data, compliant with a G.hn standard for home networking to a plurality of customer premise equipment (CPE) devices, over twisted pairs cables, said system comprising:

• a device for transmitting data compliant with G.hn, comprising:
• a memory and a processor;
• a G.hn access multiplexer (GAM) configured for broadcasting data over coax cable and having a coax port;
• a coax to twisted pair cable transformer having a coax port connected to the coax port of said GAM and a twisted pair port;
• a single port to N-ports twisted pair splitter, wherein the single port is connected to the twisted pair port of the coax to twisted pair cable transformer, wherein Nis an integer;
• N CPE devices configured to receive and transmit G.hn compliant data over coax cable, each one of the N CPE devices having a twisted pair cable to coax transformer,
• a bundle of at least N twisted pair cables connected on one end to the N-ports of the twisted pair splitter and on another end to the twisted pair cable to coax transformers of the N CPE devices;
• a controllable amplifier having a first and a second terminal, the amplifier is located between the GAM and the bundle of twisted pairs, forming a signal path, and arranged amplify time division duplex (TDD) signals received at one of said first and second terminals for transmission from the other of said first and second terminals, said controllable amplifier being operable in a first configuration for amplifying TDD signals in one direction along the signal path and a second configuration for amplifying TDD signals in an opposite direction along the signal path;
• a control circuit arranged to detect a silent period in said signals and, in response to detecting a silent period, control said amplifier circuit to change the configuration;
• and
• an array of N adjustable phase shifters, each connected to one of the twisted pair cables, enabling an adjustment of the phase post installation.

A method of installing a system for transmitting data, compliant with a G.hn standard, to a plurality of customer premise equipment (CPE) devices, over an existing infrastructure of twisted pairs cables, said method comprising:

• connecting to at least one uplink port a device for transmitting data compliant with G.hn, said device comprising:
• a G.hn access multiplexer (GAM) configured for transmitting data over coax cable and having a coax port;
