US12444853 - Methods and systems for provisioning of telecommunications signals in moving trains

Systems and methods are provided for provisioning of telecommunications signals in moving trains. A scattering panel configured for redirecting signals in a train system, with the scattering panel having a plurality of facets. The plurality of facets together may combine to provide a plurality of adjacent curved reflectors, with at least one facet of the plurality of facets facing in a different direction relative to at least one other facet of the plurality of facets, with at least one facet of the plurality of facets having one or more flat planar surfaces and at least one other facet of the plurality of facets having a curved surface portion, and with at least one facet of the plurality of facets having structures configured for modifying signals propagating over a surface of the at least one facet in at least one direction relative to the surface.

This patent describes a communication system featuring a scattering panel designed to redirect telecommunications signals within moving trains, utilizing a plurality of facets that form adjacent curved reflectors. Each facet can have different orientations and includes structures that modify signal propagation across its surface, enhancing signal quality in a dynamic environment.

Claim 1

A communication system comprising: a scattering panel configured for redirecting signals in a train system, the scattering panel comprising a plurality of facets, wherein: the plurality of facets together combine to provide a plurality of adjacent curved reflectors; at least one facet of the plurality of facets faces in a different direction relative to at least one other facet of the plurality of facets; at least one facet of the plurality of facets comprises structures configured for modifying signals propagating over a surface of the at least one facet in at least one direction relative to the surface; and the structures are aligned transverse to a direction of separation of the scattering panel from a source of the signals propagating over the surface of the at least one facet. a scattering panel configured for redirecting signals in a train system, the scattering panel comprising a plurality of facets, wherein: the plurality of facets together combine to provide a plurality of adjacent curved reflectors; at least one facet of the plurality of facets faces in a different direction relative to at least one other facet of the plurality of facets; at least one facet of the plurality of facets comprises structures configured for modifying signals propagating over a surface of the at least one facet in at least one direction relative to the surface; and the structures are aligned transverse to a direction of separation of the scattering panel from a source of the signals propagating over the surface of the at least one facet. the plurality of facets together combine to provide a plurality of adjacent curved reflectors; at least one facet of the plurality of facets faces in a different direction relative to at least one other facet of the plurality of facets; at least one facet of the plurality of facets comprises structures configured for modifying signals propagating over a surface of the at least one facet in at least one direction relative to the surface; and the structures are aligned transverse to a direction of separation of the scattering panel from a source of the signals propagating over the surface of the at least one facet.
