摘要： Apparatuses, methods, and systems for a surface wave based wireless connection to an electronic device are disclosed. One apparatus includes a surface wave guide that supports propagation of electro-magnetic waves over a two-dimensional conductive surface of the surface waveguide, wherein the two-dimensional conductive surface is treated to increase a surface reactance of the two-dimensional conductive surface over a frequency range of the electro-magnetic waves, while maintaining an insertion loss of the surface waveguide below a threshold. A first mode converter operates to couple electro-magnetic waves of a first mode to the two-dimensional conductive surface having a second mode, wherein the electro-magnetic waves of the second mode propagate across the two-dimensional conductive surface of the surface waveguide. At least a portion of the electro-magnetic waves of the two-dimensional conductive surface is coupled to an electronic device through a second mode converter of the electronic device.

摘要： A managed access system is for mobile wireless devices (MWDs) in a facility geographically within a wireless communications network of a communications carrier. The system may include at least one RF antenna arranged at the facility and including an RF launch structure, and an elongate electrical conductor having a proximal end extending through the RF launch structure and a distal end spaced apart from the RF launch structure to define an elongate RF coverage pattern. The system may further include radio equipment coupled to the at least one RF antenna, and a management access controller cooperating with the radio equipment to communicate with a given MWD in the elongate RF coverage pattern within the facility, block outside communications via the wireless communications network when the given MWD is an unauthorized MWD, and provide outside communications via the wireless communications network when the given MWD is an authorized MWD.

摘要： A radio frequency (RF) communications system may include a local RF communications device and an RF antenna coupled to the local RF communications device. The RF antenna may include a cavity backing housing, a conical RF launch structure having an apex positioned within the cavity backing housing, and an elongate electrical conductor having a proximal end extending through the apex of the conical RF launch structure and a distal end spaced apart from the conical RF launch structure to define an elongate RF coverage pattern. The system may further include at least one remote RF communications device within the elongate RF coverage pattern to wirelessly communicate with the local RF communications device.
