They are an adaptation of the old BPL (Broadband over Power Line) equipment that was tried by the electrical utilities to get into the Internet provider business years ago, but it had a number of problems when trying to provide service to neighborhoods. However, the technology worked quite well in individual homes since the wiring runs were quite short and the PLNA was born. The important thing is that it works and doesn't require running Ethernet cables in the home. It certainly shortens the install time.
