Broadband power lines or BPL is also called Power line communication. This technology has shown a faster development in Europe compared to the US. In this technology large power grids are used to transmit power at high voltages to reduce any transmission loss and the customer end step-down transformers are used to reduce the voltage. One should note here that Broadband power lines or BPL signals are unable to pass through the transformers so repeaters should be attached to the transformers. They provide fast and easy internet access and also promise consistency. They can be used by individual user and small organizations.
