Cost factor and transmission quality
dLAN is an especially easy-to-use networking technology. You don't need to
lay cables and you can connect to the 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.
Depending on the attenuation factor, dLAN is capable of covering distances
of at least 200 meters.
With a maximum data transmission rate of 14 Mbps and symmetrical upload
and download, the dLAN standard is equivalent to classical Ethernet net-
working solutions and is faster than the wireless standard 802.11b. Depend-
ing on the line quality, bandwidths of 6 to 8 Mbps are possible in practice—
quite sufficient for extending the Internet connection.
Data security and radiation
For security reasons, DES
pro
encryption is used, which guarantees secure
data transfer within the network. In addition, the power meter in the building
can act as a physical barrier against unwanted access from outside.
dLAN devices from devolo meet the stringent EU industrial standards and
comply with the current standards for electromagnetic radiation. Its radiation
level is actually well below that of Wireless LAN technologies.
