Interference generated by PLC-access-networks:
1. Demonstration of severe interference
caused by various PLC-technologies
to
shortwave broadcasting signals.
Even
strong broadcasting signals on shortwave are being interfered. Not even the
language of the broadcasting speaker can be identified !!

2.
Demonstration of a PLC-system using frequency hopping-technology in
the range 2 – 26 MHz. Display of spectrum with a spectrum analyzer. Demonstration
of severe interference to shortwave broadcasting as well as to amateur
radio signals on the frequencies 13,665 (broadcasting) and 14,211 MHz
(amateur). Reception of the HF-signals is made impossible.
Severe interference to all amateur bands between
3,5 and 24 MHz.
Proof of interference being caused by PLC by
reduction of interference when driving away from the PLC-network

Interference generated by
Inhouse PLT-Modems: HOME PLUG
3.
Demonstration of an interfering signal generated by
inhouse-PLC-modems using Intellon chipset able to interfere with any
short-wave radio receiver being operated in some distance to the location
of the PLC-modem; display of the spectrum used by the modem (approx. 4 – 22
MHz)
