Abstract: In accordance with one or more embodiments, a surface wave launcher is configured to transmit and receive guided electromagnetic waves via the aperture that propagate along a transmission medium without requiring an electrical return path. The surface wave launcher includes a coaxial port having an inner conductor and an outer conductor. A conductive tray is coupled to the inner conductor and is configured to surround, at least in part, a portion of the transmission medium. A dielectric layer surrounds, at least in part, a portion of the conductive tray. A conductive cone, is coupled to the outer conductor at a feed-point of the conductive cone, and coaxially surrounds the transmission medium, wherein the conductive cone is adjacent to the dielectric layer at the feed-point and forms an aperture.

Abstract: In accordance with one or more embodiments, an access point includes a first communication interface that receives, first guided electromagnetic waves from a first waveguide system wherein the first guided electromagnetic waves convey a first plurality of resource blocks containing first data. A data switch selects first selected portions of the first data corresponding to a first subset of the first plurality of resource blocks for transmission to at least one communication device in proximity to the access point and select second selected portions of the first data corresponding to a second subset of the first plurality of resource blocks by omitting the first subset from the first plurality of resource blocks. A second communication interface generates second guided electromagnetic waves conveying the second selected portions of the first data to facilitate reuse of the first subset of the first plurality of resource blocks by a second waveguide system.
