Abstract: Method and system for powerline local area network over coaxial cable. According to an embodiment, the present invention provides a powerline communication system. The system includes a data connection that is configured to communicating a first signal in a first format. The data connection includes an input/output port. The system also includes a powerline module coupled to the input/output port of the data connection. The powerline module has a data port. The powerline module is configured to convert the first signal in the first format into a second signal into a second format. The first format is different from the second format. The system additionally includes an analog front end device that coupled to the dataport of the powerline module. The analog front end device is configured to condition the second signal for transmission over one or more powerline and/or one or more coaxial cables. Furthermore, the system includes a coupler device coupled to the analog front end device.
