Abstract
Systems and methods are provided for provisioning of telecommunications signals in moving trains. Scattering panels may be utilized for redirecting wireless signals, such as by scattering them, to provide better communication performance on the moving trains. The scattering panels may be configured to scatter the signals, such as by reflecting them. The scattering panels may be configured for operation in conjunction with a number of antennas that communicate the signals being scattered via the scattering panels.
Claims21
A scattering panel configured for redirecting signals in a train system, the scattering panel comprising:
- a plurality of facets, wherein:
- each facet of the plurality of facets faces in a different direction to at least one other facet of the plurality of facets;
- each facet comprises a conductive planar surface of one of a plurality of sheet-like members of the scattering panel;
- members of the plurality of sheet-like members are coupled to one another along their edges such that facets of the plurality of facets together combine to provide a plurality of adjacent concave reflectors;
- at least one facet of the plurality of facets comprises one or more flat planar surfaces and at least one other facet of the plurality of facets comprises a curved surface portion;
- and
- at least one facet of the plurality of facets comprises shaped structures that are disposed on a surface of the at least one facet, wherein the shaped structures are configured for modifying one or more parameters relating to signals propagating over the surface in at least one direction relative to the surface.
A scattering panel comprising:
- a trapezoidal prism comprising a base, a front face and a pair of side faces, wherein each side face connects an edge of the base to an edge of the front face;
- a pair of plate-like fins comprising a front face and a back face, the fins extending from either side of, and parallel to, the base of the trapezoidal prism;
- and
- an inverted triangular prism, wherein an apex edge of the triangular prism is connected along its length to the center of the front face of the trapezoidal prism to divide the front face into a first side and a second side;
- wherein each of the first and second sides of the front face of the trapezoidal prism, the side faces of the trapezoidal prism, and the front face of the plate-like fins comprises electrically conductive facets for reflecting signals.
