Just trying to catch up on this broad band PLC stuff. Does this happen
in our universe?:
"Portell uses microwave technology to pull data through the magnetic
field created by alternating current flowing through the electrical
power grid. The United States electric power system operates at 60
cycles a second or hertz. This means that the electric charges or
current flowing in the system changes direction 60 times every second.
The AC is what causes the radiation of the magnetic field that surrounds
the electrical wires. Electric fields are easily shielded or weakened by
conductive objects but magnetic fields are not. Modulating signals onto
the magnetic field, instead of the electrical field, is what allows
Portell to transmit signals through transformers, over high voltage
electrical transmission (110KV) and distribution (11KV) lines, at speeds
up to 2.5 gigabits per second. Microwave signals propagated onto the
magnetic flux field can travel up to 2000 miles without regeneration.
The process writes telephone, radio, video, Internet and satellite data
within the magnetic wave by using proprietary software and hardware.
This allows the electrical grid to carry these communications services
at near light speed."
