Abstract

A network interface device includes a first interface, a power extractor, a transceiver, and a second interface. The first interface receives a signal that includes both power and packetized information. The power extractor extracts the power from the signal and powers the transceiver. The transceiver extracts the packetized information from the signal and communicates the information to a user device using the second interface.
