The system used some PLC HE (head end) with capacitive and inductive coupling (one, two
or three phase to neutral, phase to phase and any other combination) and other PLC modem
with only capacitive coupling (only phase to neutral). Frequency used, varied between 13.8
to 16.3 MHz in upstream, and between 19 to 22.8 MHz in downstream. The injected signal
level was of 30 dBm (at the maximum) and the data transfer rate reached the speed of 27
Mbps in downstream and 18 Mbps in upstream.
The first commercial application based on the PLC technology was launched in December
2003 in the Riverside apartment-house in Budapest by 23Vnet Ltd. After 4 months the
service was counting 100 users from 450 apartment owners. The bandwidth is 4.5 Mbps.
