Pretty easy, right? Gefen
's new $199 GefenTV Ethernet over PLC Extender takes regular ole Ethernet and passes information through your home's pre-installed power lines in order to nix those plans of running 200-foot strands of CAT5 down the middle of your foyer. The device enables up to four Ethernet connections to be extended over power lines, and everything can be sent without quality loss (and at up to 200Mbps) as long as the sender is within 1,000-feet of the receiver. Put down the Ethernet spool, and slowly back away.
