Abstract: Aspects of the subject disclosure may include, for example, receiving wirelessly a first transmission of data from a network interface device, wherein the network interface device includes a receiver and a transmitter. The network interface device receives, via the receiver, electromagnetic waves that propagate on a surface of a dielectric transmission medium. The network interface device converts, via the receiver, the electromagnetic waves to an electrical signal, and transmits, via the transmitter, a first transmission of the data based on the electrical signal. A determination is made that the data is to be directed towards a recipient device connected to at least one electrical circuit and, based on the determination, a second transmission of the data is initiated as a power line communication transmission of a utility power line via the at least one electrical circuit. Other embodiments are disclosed.

Abstract: In accordance with one or more embodiments, a transmission device includes a transmitter configured to generate a transmit signal conveying transmit data in accordance with a communication protocol having first protocol transmit parameters. A coupler is configured to convert the transmit signal to transmitted guided electromagnetic waves that propagate along a surface of a transmission medium without requiring an electrical return path. The coupler is further configured to convert to a receive signal, received guided electromagnetic waves from a remote device that propagate along the surface of the transmission medium, wherein the remote device is configured to receive the transmitted guided electromagnetic waves. A corona discharge detector is configured to generate, based on the receive signal, corona discharge data that indicates corona discharge activity in proximity to the transmission medium during a time period. Responsive to the corona discharge data, the transmitter modifies the communication protocol to second protocol transmit parameters.
