Abstract

A broadband powerline communications device includes a plug for connection to mains electrical wiring, a broadband powerline medium interface circuit for communicating broadband data over the mains electrical wiring, at least one electrical socket for providing mains electrical power from the mains electrical wiring to a further device plugged thereto, and energy consumption monitoring circuitry for monitoring the energy consumption of the further device. These components are formed in a housing with the plug is integrally formed with the housing or separated from the housing by a length of power cable. The device may also include a communications socket for wired communications and/or a wireless router for servicing wireless communications. The device may further include a mains filter with one or more components of the mains filter used in determining the instantaneous level of the voltage and/or current supplied to the further device.
