some of the BPL Network deployment options
BPL works by transporting the Internet data signal over the existing medium voltage network. Working on overhead or underground electric grids, the signal is inserted at a point which becomes the hub for that portion of the network, or cell. The hubs can connect to the Internet by any means available, whether dedicated circuit (T1), fiber links, or wireless data links.
The data signal is then transported through the medium voltage network with a repeater boosting the signal in selected locations for greater cell coverage. Typically, repeaters are placed throughout the grid to extend the service and especially at transformer locations in the areas to be served. Repeaters are monitored 24/7 for continued operation, giving the utility the added benefit of using the BPL network as a transformer monitoring system.
From that point, the data can be transmitted to the homes or businesses either
through the low voltage lines to each outlet in the building. In some areas,
neighborhoods can be served with wireless links from the power poles to an antenna
on the building. Office buildings or multi-dwelling units can serve as their
own cell with low voltage repeaters delivering the data signal to every outlet
in the building.
