Powerline: Technical Background
Powerline is a network technology that uses existing electrical wires
for data transmission. The data signals are modulated onto the power
lines.
Data Transmission through Modulation (OFDM)
Powerline uses OFDM (Orthogonal frequency division multi-
plexing) for this modulation.
The powerline adapter works as a power line communication
system.
Sending adapters modulate the data signals to a carrier fre-
quency; in other words, the carrier frequency is changed. Re-
ceiving adapters demodulate the data signals, meaning that
they change the modulated frequency back to the carrier fre-
quency and the original data signal.
Standard: IEEE P1901
FRITZ!Powerline complies with the IEEE P1901 standard.
IEEE P1901 is a standard that defines the settings for net-
works over power lines.
IEEE P1901 provides for data transmission rates of up to
500 Mbit/s.
