Many customers have to share a single PLC access point
The achievable bandwidth and download
rate is significantly lower than
customers expect. PLC
can create broadband noise alongside broadband internet access.
Since all users share
the same physical access, data sniffing
can be done and security
is a problem. PLC is more like a wireless LAN in terms of security,
since it makes use of radio frequency.
RF
energy is always
present, not only along the wire that is currently in use,
but also in all sleepingrooms and even at all neighbours.
PLC could cause malfunctions
of your electrical equipment, such as battery chargers, audio-video
systems, etc.
To receive telecommunication
services and energy from the same company will create a dangerous
new monopoly.
If PLC causes interference
to important radio services, the user might be held responsible
for the damage.
If PLC
field trials are not successful, all cost might be charged to the electricity
bill as „stranded cost“.
