Abstract: Aspects of the subject disclosure may include, for example, a transmission medium for propagating electromagnetic waves. The transmission medium can include a conductor for guiding electromagnetic waves longitudinally along the conductor, and a shell surrounding at least a portion of the conductor for reducing exposure of the electromagnetic waves to an adverse environment that increases propagation losses of the electromagnetic waves. Other embodiments are disclosed.

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, for example, a system that performs operations including receiving first electromagnetic waves on an outer surface of a transmission medium, detecting a degradation of a signal quality of the first electromagnetic waves due to first electric fields of the first electromagnetic waves inducing first currents in an obstruction disposed on the outer surface of the transmission medium, and generating second electromagnetic waves having second electric fields that induce second currents in the obstruction that are lower in magnitude than the first currents, the electromagnetic waves having a cutoff frequency. Other embodiments are disclosed.

Abstract: A distributed antenna and backhaul system provide network connectivity for a small cell deployment. Rather than building new structures, and installing additional fiber and cable, embodiments described herein disclose using high-bandwidth, millimeter-wave communications and existing power line infrastructure. Above ground backhaul connections via power lines and line-of-sight millimeter-wave band signals as well as underground backhaul connections via buried electrical conduits can provide connectivity to the distributed base stations. An overhead millimeter-wave system can also be used to provide backhaul connectivity. Modules can be placed onto existing infrastructure, such as streetlights and utility poles, and the modules can contain base stations and antennas to transmit the millimeter-waves to and from other modules.

Abstract: Aspects of the subject disclosure may include, for example, a system that performs operations including receiving electromagnetic waves on an outer surface of a transmission medium having a non-hybrid wave mode and a cutoff frequency, detecting a degradation of a signal quality of the electromagnetic waves, generating adjusted electromagnetic waves having a hybrid wave mode and a non-optical frequency range responsive to the detecting, and directing the adjusted electromagnetic waves having the hybrid wave mode and the non-optical frequency range to the outer surface of the transmission medium for guiding propagation of the adjusted electromagnetic waves without utilizing an electrical return path. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a transmission device that includes a transmitter that generates a first electromagnetic wave to convey data, the first electromagnetic wave having at least one carrier frequency and corresponding wavelength. A coupler couples the first electromagnetic wave to a transmission medium having at least one inner portion surrounded by a dielectric material, the dielectric material having an outer surface and a corresponding circumference, wherein the coupling of the first electromagnetic wave to the transmission medium forms a second electromagnetic wave that is guided to propagate along the outer surface of the dielectric material via at least one guided-wave mode that can include an asymmetric mode, wherein the at least one carrier frequency is within a microwave or millimeter-wave frequency band and wherein the at least one corresponding wavelength is less than the circumference of the transmission medium. Other embodiments are disclosed.
