hold power grid to transfer data between computers
and other network components equipped with suitable
adapters. As a result, any electrical socket can be used
as a network access point. The data is modulated prior
to transfer and sent as a signal via household power
lines. State-of-the-art technology ensures that the
power and data networks do not interfere with one an-
other. Networking via dLAN is fast and secure. The
data is encrypted using a key to prevent interception by
third parties.
