ABSTRACT
Broadband over Power Lines network is overlaid on the
medium-voltage and low-voltage segments of the power distribution system.
High-speed backhaul connections can be brought to the BPL network at
substations or elsewhere along the medium voltage circuit. An Ambient node
provides connectivity between the backhaul connection and the medium voltage
segment of the BPL network. High speed data travels over this medium-voltage
segment to remote locations where is it transferred to the low-voltage segment
or to a wireless interface for the final leg to the end user or network element
being managed. A simplified view is shown is Figure 1.2.
An alternative injection technique, known as “conductive coupling” connects the
signal cable directly to the electricity cables but requires the power to be
switched off during connection for safety reasons.
The end-user simply connects a BPL modem to any power socket
in the building for access to the BPL RF signal. The BPL modem converts the RF
signal back into IP data. The enduser user then connects the BPL modem into a
computer, server, switch, or wireless access point.
