This is partly incorrect. Near the beginning of using data over coax cables the network architecture design dedicated more frequencies to getting data to your house as opposed to you sending data out. This was done because the initial network design was that they would send massive amounts of data to you as images and you would only send small amounts of data requesting paper view or other channel/media options. All components through out the network rely on what came before.
