crosstalk from one phase to another inside the apartment, but over the rising mains
from one circuit in the residential unit to the circuit in another residential unit.
However, by using non-standard encryption (dLAN password) in a peer-to-peer
network, you can to prevent unauthorised parties from gaining access to the
encrypted data. Another option for protecting the privacy of the individual household
is to operate the dLAN adapters with peer-to-peer isolation. A master dLAN 200
AVpro2 could supply two parties with Internet data over the power supply system in
this manner, as in the example shown above. The two parties would not "see" each
other, and each would only have access to the master, which is connected to the
Internet gateway.

A three-phase circuit also exists in each housing unit as well in this
example, but has been excluded from this illustration for the sake of clarity.
The distribution box does not
attenuate as a rule.
You should note that the
dLAN system has not been developed for
crosstalking across apartments globally
. You should make sure you test this
type of system for correct functioning in the respective surroundings in
advance for this reason. In this example, a phase coupler (installed in a
control cabinet serving one or more apartments ) does not act as an aid for
the coupling in the feed line (or between the apartments)!
