The system is based around this device:

The wireless ISP rep indicated that the power over ethernet line had
resulted in intereference for some local HAM users, and suggested a
shielded cable and/or selective routing may solve the problem.


I've not heard of any problems with power-over-ethernet causing
interference to hams. (that said, this is the first I've heard of
power-over-ethernet period!)


Snip

Think of small switching power supplies running on 24 to 48 volts and
switching from 100 to 500 KHz. Bad news. Bad, bad, bad.

The idea is to be able to connect networked devices and also power them
over the ethernet cable.

Not popular yet and I hope it stays that way. It's been around a few
years now. Besides the noise generation potential its a lame idea anyway.
