Abstract: Aspects of the subject disclosure may include, for example, a repeater device having a first coupler to extract downstream channel signals from first guided electromagnetic waves bound to a transmission medium of a guided wave communication system. An amplifier amplifies the downstream channel signals to generate amplified downstream channel signals. A channel selection filter selects one or more of the amplified downstream channel signals to wirelessly transmit to the at least one client device via an antenna. A second coupler guides the amplified downstream channel signals to the transmission medium of the guided wave communication system to propagate as second guided electromagnetic waves. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, generating, by a first hollow waveguide coupled to a first dielectric coupler, a first electromagnetic wave that couples onto a transmission medium, generating, by a second hollow waveguide coupled to a second dielectric coupler, a second electromagnetic wave that couples onto the transmission medium, combining the first electromagnetic wave and the second electromagnetic wave combine to form a combined electromagnetic wave that propagates along the transmission medium without requiring an electrical return path, and adjusting a first phase of the first electromagnetic wave, a second phase of the second electromagnetic wave, or both to adjust a wave mode of the combined electromagnetic wave. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, receiving an electrical signal, and generating on an outer surface of a transmission medium, according to the electrical signal, electromagnetic waves having a target wave mode. At least a portion of electric fields of the electromagnetic waves has a spatial alignment that reduces a propagation loss of the electromagnetic waves when the electric fields of the electromagnetic waves propagate through a substance disposed on the outer surface of the transmission medium in a direction of propagation of the electromagnetic waves. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a waveguide system for transmitting first electromagnetic waves via a coupler located in proximity to a transmission medium to generate second electromagnetic waves that propagate on an outer surface of the transmission medium, the transmission medium further providing a first power signal having a first operating frequency and a second power signal having a second operating frequency that differs from the first operating frequency. The waveguide system can further obtain energy from the first power signal for powering the waveguide system. Other embodiments are disclosed.
