1 Introduction
This chapter gives you an overview of the new dLAN technology and a brief
introduction to the dLAN duo.
1.1 What exactly is dLAN?
There is now a new alternative to the well-known wired LAN and Wireless LAN
network technologies currently used in home networking: dLAN (direct LAN, i.e.
directly networked). dLAN is home networking using the electric wiring already
installed in the building.
Cost factor and transmission quality
dLAN is an economical and easy-to-use networking technology. You don't need
to lay cables and you can connect to the home network at every power point.
The dLAN technology modulates and demodulates additional frequencies on the
power lines. 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. Now it is used to set up Internet and network accesses in the home or
office. Depending on the damping factor, distances of up to 200 meters can be
covered.
With a maximum data rate of 14 Mbps and symmetrical upload and download
speeds, dLAN is comparable to traditional Ethernet network solutions and the
current WIFI
TM wireless standard for home applications.
Data security and radiation
For the sake of security, the DES
pro
encryption is used to guarantee secure data
transfer within the network.
dLAN devices from devolo meet the stringent EU industrial standards and com-
ply with the current standards for electromagnetic radiation.
