2. Introduction
In this chapter, we will provide an overview of the Homeplug technology and
introduce it briefly.
2.1 What exactly is Homeplug?
Homeplug is home and office networking using the electric wiring already
installed in the building.
Cost factor and transmission quality
Homeplug 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 Homeplug 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 at least 200
meters can be covered.
With a maximum data rate up to 500 Mbps and symmetrical upload and
download speeds, Homeplug is comparable to traditional Ethernet network
solutions.
Data security and radiation
128-bit AES encryption is used, which guarantees secure data transfer within the
network.

BLINKING: Ethernet traffic detected.
OFF: No Ethernet Link detected.
PLC Link/Activity
LED
ON: Power line Link detected but no power line traffic.
OFF: Power line Link not detected (either other devices in same network are too
far to communicate or it is alone in its logical network).
Color:
Green: PHY RATE > 40Mbps
Orange: 20Mbps < PHY RATE < 40Mbps
Red: PHY RATE < 20Mbps
GROUP/Reset
Button
Press 10 seconds: clear the current network group name and randomly generate a
new network group name.
Press 2 to 3 seconds: this will enter Group pairing mode. In this mode the device
will join into an existing logical network of other device or announce its network
group name for other devices to join. This mode automatically ends after two
minutes or when it is successful, manually stopped. Press this button 2 to 3
seconds will manually stop the Group pairing mode.
