Abstract
A multi-point computer networking system for transmitting data over power lines is built into a computer. The networking system includes a 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 shares the main power cord with the computer. Therefore, only one power cord is needed for each computer to serve both AC power and data networking functions.
