Sure sounds like BPL!<br>

This is not BPL, they are just mounting radios above the power space on<br>
utility lines. They are not modulating any signals over the power grid.<br>
<br>

Honestly? Can't kill this zombie? I thought fibre to the home was finally<br>
going to put this one to bed - you can push far more bandwidth down a glass<br>
pipe than a copper one anyway, with far less interference to OR FROM people<br>
like us, emergency services, radio astronomy, etc, not to mention better EMP<br>
resiliency.<br>
<br>
Perhaps FTTH isn't easy enough to wiretap? :-(<br>
