2 OVERVIEW OF POWERLINE MU
Motorola Powerline MU Solution provides a broadband over low-voltage power line
access solution that delivers reliable performance to multiple-dwelling units while
mitigating interference by using low voltage wires. Motorola Powerline MU is designed
for and works with the Canopy™ wireless broadband Internet platform. The standard
Canopy system provides the broadband backbone for the system, creating a wireless
transport system to the hotel, apartment building, or other multiple dwelling unit.
Figure 1 Powerline MU Network Overview
The Canopy Subscriber Module (SM) is the termination unit of the wireless part of the
system and consists of a single transceiver that operates with a 60-degree antenna and
communicates with one or more Access Points (AP). The synchronization and control of
the SM is accomplished via the received AP signal. After the SM is turned on, it scans
the channels and automatically registers with an AP.
The Category 5 Ethernet output cable from the SM plugs directly into the Powerline MU
Gateway unit or via a Powerline MU Hybrid Adapter. Power to the SM is supplied by use
of the SM “pigtail” electric cord. The integrated Subscriber Module (SM)-Powerline
Gateway unit provides signal routing to the Modem devices within the home.
When the Gateway is connected to the low voltage side of the power transformer, digital
data is transmitted over the power line. By using this technique and adding notch filtering
