In this chapter we provide you with an overview of dLAN technology and briefly
present the dLAN 200 AVpro WP adapter. Furthermore, at the end of the chap-
ter you can find some illustrations showing examples of networking.

What exactly is dLAN?

There is now an exciting new alternative to the familiar cable-based and wireless
technologies, LAN and Wireless LAN: dLAN (direct Local Area Network, i.e. net-
worked directly). dLAN uses power cables that have already been installed to
enable data communication.
Cost factor and transmission quality
dLAN is an economical and easy-to-use networking technology. Cables no
longer need to be installed, and any socket outlet can be used to connect to the
network.
With dLAN, additional frequencies are modulated on the power circuits. Modu-
lation and demodulation is a well-known and proven method of data transmis-
sion, which has been in use in other applications for a number of years.
Depending on the properties of the circuit and the damping factor, distances of
up to 200 meters can be spanned with the power circuit.
The standard HomePlug AV is used for transmission of data over the power sup-
ply grid with the dLAN 200 AVpro WP. HomePlug AV uses the domestic power
infrastructure to transmit data, audio and video in just the same way as the
proven HomePlug 1.0 technology. But HomePlug AV is much faster: with a
transmission rate of 200 Mbps and its "Quality of Service" functions (QoS),
HomePlug AV technology is ideal for Triple-Play services, and is thus entirely
capable of handling the enormous range of new online entertainment options.
HomePlug AV adapters and HomePlug 1.0 devices can be operated together in
the same power grid. Though data can not be transmitted between these two
HomePlug standards.
Data security and radiation
dLAN 200 AVpro WP devices are secured via "AESpro 128". This is a combina-
tion of "128-bit triple AES encryption" (Advanced Encryption Standard) and a
time lock when entering a new password. This procedure represents reliable pro-
