Power transfer apparatus for concurrently transmitting data and power over data wires

A power transmission adapter for concurrently transmitting a power supply current and a data signal at distances over three meters comprising:

• an electrical power port for receiving the power supply current;
• a data communication port adapted for receiving the data signal, the data signal having a data transfer rate of one Megabits per second or higher, the data signal including a local area network data signal;
• an output port having one or more data signal conductors adapted for transmitting the data signal;
• and
• a coupling circuit, coupled to the electrical power input port, the data communication port and the output port, the coupling circuit couples the data signal and the power supply current to create a coupled signal and transmits the coupled signal to the data signal conductors, the data signal conductors are coupled to at least one network access point, the coupled signal includes a power output sufficient for operation of the network access point.

A power transmission adapter for decoupling a power supply current and a data signal from a coupled signal comprising:

• an input port having one or more data signal conductors adapted for receiving the coupled signal;
• an electrical power output port for transmitting the power supply current;
