Electric Company Using Power Lines for Data
Snags writes: "The local electric company PPL Utilities is testing a system to send electricity usage readings back to the company over its own power lines. According to a local newspaper article, they are using the TWACS system made by DSCI. I'm just hoping this doesn't interfere with other ideas for sending data over power lines."
X10 cameras don't use X10 protocol over the powerline... They transmit wirelessly at 2.4 ghz...
Also, many companies are working on trying to use SCP over powerlines.... Supposedly more efficient then X10, more robust, and allows low bandwidth data transfer. Not succeptible to phase-loops like X10 either... Stuff like that... But I think its still a year or two out...
