1 Introduction

In this chapter, we will provide an overview of the dLAN technology and intro-

duce the dLAN 200 AVpro i briefly.

1.1 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 or coaxial 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 or coaxial cable outlet can be used

to connect to the network.

With dLAN, additional frequencies are modulated on the power and coaxial cir-

cuits. Modulation and demodulation is a well-known and proven method of

data transmission, which has been in use in other applications for a number of

years. Depending on the properties of the circuit and the damping factor, dis

tances of 200 meters can be spanned with the power circuit; over 750 meters is

possible over the coaxial circuit.

In order to transmit data over the power supply grid or the coaxial network, the

dLAN

200 AVpro i is used in conjunction with Standard HomePlug AV. Home-

Plug AV uses the domestic power or coaxial 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, 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 and HomePlug 1.0 can be operated together on the same power

network. Data can be exchanged between HomePlug 1.0 networks and Home-

Plug AV networks via a bridge. One HomePlug 1.0 adapter and one HomePlug

AV adapter simply have to be plugged into adjacent sockets and connected

directly with an Ethernet cable.
