Abstract: Aspects of the subject disclosure may include, for example, a system including a frequency mixer that combines a signal and a carrier wave to form a combined signal, and a transmitter that generates a transmission based on the combined signal. The system can also include a coupling device that emits the transmission as an electromagnetic wave guided by an outer surface of a transmission medium. The electromagnetic wave can propagate longitudinally along the surface of the transmission medium and at least partially around the surface of the transmission medium.

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, a system that facilitates detecting first electromagnetic waves propagating along a transmission medium are experiencing a first propagation loss, inducing second electromagnetic waves along the transmission medium to mitigate the first propagation loss, detecting that the second electromagnetic waves are experiencing a second propagation loss and inducing third electromagnetic waves along the transmission medium to mitigate the second propagation loss. To reduce radiation losses when transitioning from the first electromagnetic waves to second electromagnetic waves and transitioning from the second electromagnetic waves to the third electromagnetic waves, the system can be further adapted to use differing criteria for each transition. Other embodiments are disclosed.
