Abstract: Aspects of the subject disclosure may include, a coupler having a first member coupled to a transmission medium, a first component coupled to the first member, a second member coupled to the transmission medium, and a second component coupled to the second member. The first component can facilitate transmission of first signals via the first member, and the second component can facilitate transmission of second signals via the second member. The first signals and the second signals can in turn induce electromagnetic waves that propagate along the transmission medium without requiring an electrical return path. Other embodiments are disclosed.

Abstract: In accordance with one or more embodiments, an access point includes a first communication interface having: a first coupler configured to receive, via a first transmission medium, first guided electromagnetic waves from a first waveguide system of a distributed antenna system, wherein the first guided electromagnetic waves propagate along the first transmission medium without requiring an electrical return path; and also a first receiver configured to receive first data from the first guided electromagnetic waves. A data switch is configured to select first selected portions of the first data for transmission to at least one communication device in proximity to the access point.

Abstract: Aspects of the subject disclosure may include systems, apparatuses, methods, and computer-readable media for facilitating operations. The operations may include transmitting a first electromagnetic wave, where the first electromagnetic wave is guided by and propagates along a first transmission medium without requiring an electrical return path, and transmitting a second electromagnetic wave, where the second electromagnetic wave is guided by and propagates along a second transmission medium without requiring the electrical return path, the second transmission medium being different from the first transmission medium. Other embodiments are disclosed.

Abstract: A transmission device includes a coupler configured to convert a transmit signal to transmitted guided electromagnetic waves that propagate along a surface of a transmission medium without requiring an electrical return path, the coupler further configured to convert to a receive signal, received guided electromagnetic waves that propagate along the surface of the transmission medium without requiring an electrical return path. A housing is configured to provide environmental protection to the coupler. The housing includes an aperture section configured to pass the transmitted guided electromagnetic waves from the coupler through an aperture side of the housing, the aperture section further configured to pass the received guided electromagnetic waves to the coupler through the aperture side of the housing. The housing also includes a non-aperture section configured to absorb radio frequency (RF) signals in a frequency range of the transmit signal and a frequency range the receive signal.

Abstract: In accordance with one or more embodiments, a waveguide system includes a transmission device configured to send and receive guided electromagnetic waves that propagate along a surface of a power line without requiring an electrical return path. The waveguide system further includes a magnetic core that surrounds the power line, a first winding around the magnetic core that generates a supply current in response a transmission current flowing through the power line and a power supply that converts the supply current to a supply voltage that powers the transmission device. The power supply automatically stabilizes power consumption by the transmission device in response to variations in the supply current caused by variations in the transmission current flowing through the power line.
