One of the main differences between RedTrain and NBNCo is the connection technology they use. RedTrain uses FTTP (Fibre to the Premises) technology in most of their projects. FTTP exclusively uses fibre optic cables, enabling the fastest speeds in Australia. FTTP benefits from the higher capacity of a full fibre connection and will have a more stable connection and speed in general. However, in addition to FTTP, NBNCo also adopts other technologies like a combination of fibre and copper (FTTC, FTTN/B) or fibre and coaxial cable (HFC). FTTC, FTTN/B, and HFC technologies may slow down and become unstable during instances of poor weather.
