2.1 What exactly is dLAN?

dLAN (direct Local Area Network) uses the house-
hold power grid to transfer data between compu-
ters equipped with suitable adapters and other
network components. As a result, any power outlet
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 technolo-
gy ensures that the power and data networks do
not interfere with one another. Networking via
dLAN is fast and secure. The data is encrypted
using a key to prevent interception by third parties.

2.2 What is WLAN?

WLAN (Wireless Local Area Network) refers to the
use of radio technology to network computers and
other devices. While it is possible to wirelessly
connect computers in pairs (peer-to-peer, p2p), a
central access point is required to set up a network
of multiple devices. Such access points are fre-
quently combined in a single device with modems
for Internet access and routers to manage network
traffic.
The wireless network established by an access
point using a specific channel (from 1 to 13) and
name (SSID) has a limited range. The range of the
