1 Introduction
In this chapter, we will provide an overview of the new dLAN technology and
introduce the dLAN HS Ethernet briefly.
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 standard 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 u to 200 meters can be
covered.
With a maximum data rate of up to 85 Mbps and symmetrical upload and down-
load speeds, dLAN is comparable to traditional Ethernet network solutions and
the current WIFI
TM wireless standard for home applications.
Data security and radiation
DES
pro
bit encryption is used, which guarantees 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.
