A repeater device comprises a periodic array of alternating metallic phase shifting elements, the array being periodic in at least one axis, formed on a first surface of a dielectric substrate, with an opposite surface of the dielectric substrate having a ground plane formed thereon, wherein each phase shifting element provides from 0&#xb0; to 360&#xb0; phase shifting in the microwave frequency range. The repeater device can be utilized in a microwave network.

A system having a concealed communications element like a telecommunication antenna is described. More specifically, The system has a communications element that is concealed by a highly reflective multilayer polymer optical film. The first element of the multilayer polymer optical film is a core layerthat is made up of a multilayer optical stack. The multilayer optical stack of core layerincludes two alternating polymeric layers. The multilayer polymer optical film may optionally also include a protective layer(for example, a hardcoat or an over laminate) that is positioned between the viewer and the core layer. The protective layermay include one or more UV absorbers to aid in durability of the multilayer polymer optical film against UV-degradation. Multilayer polymer optical filmmay optionally also include an adhesive layerthat is positioned between the core layerand a surface onto which the multilayer polymer optical film is to be adhered.

A hybrid network for in-building wireless (IBW) applications that provides a forward link path and a reverse link path, each on separate media. In particular, a hybrid cabling system for providing wireless coverage in a building comprises a forward link comprising at least one optical fiber to couple a first signal generated at an RF input bank with an RF antenna node, and a reverse link comprising coaxial cable, wherein a portion of the reverse link includes radiating coaxial cable configured to receive a second signal transmitted by a wireless user equipment in the building and pass the second signal to the RF input bank.
