Abstract
Abstract A system and method to connect standard telephone subscriber equipment (telephone, facsimile, personal computer) to a fixed wireless terminal via power lines. The system comprises fixed wireless terminals connected to a power line interface device. Subscriber equipment is connected to the power line interface device thereby allowing telecommunication signals to be transmitted to the fixed wireless terminal for subsequent wireless transmission. The fixed wireless terminal exists at an individual subscriber's home/business within a given step-down power transformer cluster. The step-down power transformer provides signal isolation so that the same or similar addresses can be used between clusters without confusion as to the identity of the individual subscriber. The FWT is also connected to the power meter at a subscriber location such that power utilization can be communicated to the power company in a wireless fashion.
