1. A system for providing communications for user devices via a power line, comprising:
- a backhaul device including a network transceiver and a power line transceiver;
a first communication device including a first downstream transceiver and a first upstream transceiver;
wherein said power line transceiver is in communication with said first upstream transceiver, at least in part, via surface wave transmissions traversing the power line; and
wherein said first downstream transceiver is in communication with at least one user device.

Abstract
The present invention provides a system for operating a power line communications system that employs surface wave communications and conducted communications. The system is comprised of a plurality of network elements, which may take the form of repeaters, communication interface devices, backhaul devices, medium voltage transducers, distribution points, aggregation points, and others. In one embodiment, surface waves are communicated over the medium voltage power lines and the conducted communications are communicated via the low voltage power lines to and from customer premises.
