The following illustration shows an example of the differences between a P2P
network architecture (left) and a MDU network architecture (right):
Depending on the capabilities of your dLAN devices to support different cable
systems, you can use physically different cable systems as transmission mediums
for dLAN networking, specifically power lines (PowerLine 'PLC'), TV/SAT coaxial
wiring ('Coax') or telephone or two-wire cabling.
Because these different cable systems have different transfer properties depend-
ing on their design, they are not compatible with one another.
a) For dLAN networking via the existing mains supply ('PowerLine'), the
'HomePlug AV' standard is used. In this procedure, the respective dLAN
device attenuates or blocks the transmission capacity in the critical areas of
the commonly used frequency band between 1.8 to 30.0 MHz (or 1.8 to
67.5 MHz with the dLAN 500 AVpro UNI) as needed with notch filters, so
that the dLAN cannot interfere with other wireless services (such as amateur
radio). In addition, the effects of possible interference signals on the dLAN
transmission are prevented by controlling the dLAN communication with a
modulation table so that there is no dLAN transmission in the interference
signal frequency bands. Additional filters (such as block filters) can be added
as needed.
By means of PowerLine, you can bridge distances of up to 200 metres,
depending on the line quality and the attenuation factor.
 The dLAN 200 AVpro Wireless N, dLAN 200 AVpro2, dLAN 200 AVpro
WP, dLAN 200 AVpro mini and AVpro DINrail devices support transfer
rates of up to 200 Mbps by PowerLine.
 The dLAN 500 AVpro UNI and dLAN 500 AVpro+ devices support
dLAN transfer rates of up to 500 Mbps.
