1 Introduction
Intelligent and secure technologies such as dLAN
®
(networking via the
household power grid) and WLAN (wireless networking) have made setting
up a home network fast, easy and economical, while making the installation
of expensive, dedicated wiring superfluous. The available performance and
effort required for the installation also compares favorably to traditional
methods – dLAN ® and WLAN technology now attain speeds you would
expect from a conventional LAN, and installing it is a breeze!
1.1 What exactly is dLAN
®
?
dLAN ® (direct LAN) uses the household power grid to transfer data
between computers 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 technology ensures that the power and data
networks do not interfere with one another. Networking via dLAN ® is fast
and secure. The data is automatically encrypted using a key to prevent easy
interception by third parties.
1.2 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
frequently combined in a single device with modems for Internet access and
routers to manage network traffic.
