Abstract: Aspects of the subject disclosure may include, for example, a waveguide system that includes a transmission device having a coupler positioned with respect to a transmission medium to facilitate transmission or reception of electromagnetic waves that transport communications data. The electromagnetic waves propagate along an outer surface of the transmission medium. A training controller detects an impairment on the transmission medium adverse to the transmission or reception of the electromagnetic waves and adjusts the electromagnetic waves to reduce the effects of the impairment on the transmission medium. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a method for receiving a request to steer wireless signals generated by a plurality of dielectric antennas, and adjusting, by the controller, a plurality of adjustable delays coupled to a transceiver to adjust an orientation of wireless signals received or generated by the plurality of dielectric antennas, each of the plurality of dielectric antennas comprising a feed point coupled to a different one of the plurality of adjustable delays, the transceiver facilitating reception or transmission of electromagnetic waves propagating via a different one of the feed points of the plurality of dielectric antennas along corresponding dielectric feedlines without an electrical return path. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a transmission device that includes a first coupler that guides a first electromagnetic wave to a first junction to form a second electromagnetic wave that is guided to propagate along the outer surface of the transmission medium via one or more guided-wave modes. These mode(s) have an envelope that varies as a function of angular deviation and/or longitudinal displacement. Other embodiments are disclosed.

Abstract: A distributed antenna system is provided that frequency shifts the output of one or more microcells to a 60 GHz or higher frequency range for transmission to a set of distributed antennas. The cellular band outputs of these microcell base station devices are used to modulate a 60 GHz (or higher) carrier wave, yielding a group of subcarriers on the 60 GHz carrier wave. This group will then be transmitted in the air via analog microwave RF unit, after which it can be repeated or radiated to the surrounding area. The repeaters amplify the signal and resend it on the air again toward the next repeater. In places where a microcell is required, the 60 GHz signal is shifted in frequency back to its original frequency (e.g., the 1.9 GHz cellular band) and radiated locally to nearby mobile devices.

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.
