TCP/IP network system constructing by power lines

摘要

A TCP/IP network system constructing by power lines has a plurality of embedded data processors, a plurality of modems, at least a computer device or speech device, power lines which are used to construct a local network. The embedded data processor is internally connected to a computer device or a speech device and externally connected to an external broadband network. The modem is connected to other computer devices and speech devices in the local modem, or the external broadband network for data transfer.
