Abstract
A multi-point computer networking system for transmitting data over power lines is built into an external AC adapter that powers a computer device or peripheral. The networking system includes a data bus interface unit for exchanging data with a computer, a power line data transceiver unit for placing data onto and taking data off of the power line, and a network controller implementing a network protocol for sending and receiving messages. The networking system is disposed within the housing of the AC adapter. Therefore, there is no extra box or cable needed for each DC powered computer device to serve both DC power and data networking functions.
