I was in the middle of typing a reply that says basically the same thing -- I guess I'm not as fast at typing these days :-)<div><br></div><div>Basically, the same thing -- The biggest hing you need to look at is to find out if the two end-points exist on the same side of the mains. Is this commercial or residential? If it's down the road, then it may be on a separate transformer as well.<div>
<br></div><div>Even from a residential perspective, you can have issues since you have two lines coming into the house - you </div><div>may have one circuit on one side and another circuit on the other side -- the transmission may not go through/cross-over the remote transformers.</div>
<div>Similar issues arise from X10 usage as well ... different frequencies, but similar issues.</div><div><br></div><div>Naturally, injecting the type of frequencies these use into the circuitry of your house can also cause that same injection to show up unwanted on devices that receive on those frequencies ... ie: radios and the like. Interference may show up.</div>
<div><br></div><div>I'm not an advocate of Ethernet-over-power, (I'm a ham radio operator and these ethernet over power technologies spew RF everywhere) but would certainly look more to a wireless scenario.</div><div>

My understanding is that a transformer will block that frequency. I<br>
had looked into it for a while and I read some people making block<br>
wide networks, but the at least in their situation the transformer at<br>
the end of the block was filtering.<br>
<br>
Keep the list updated, this is interesting stuff. :)<br>
