A wire assembly and antenna that is configured to transmit and receive radio frequency signals and can withstand high temperatures is disclosed. The wire assembly includes a first and second wire formed from copper, steel, copper coated steel, or metallic alloy, and the wires are spaced apart from each other by a predetermined distance. This predetermined distance is maintained via applying tension to the wires and/or using separator nodes or other spacing elements. Various components of the system disclosed herein are formed from fire proof or fire resistant materials, such that the components will not fail or be compromised under extreme heat and flames.

Methods for forming continuous shields for use in a cable are provided. A first layer of longitudinally extending dielectric material may be provided, and a second layer of longitudinally extending electrically conductive material may be formed on the first layer. At a plurality of spaced locations along a longitudinal direction, respective gaps may be formed through both the first layer and the second layer, and each gap may span partially across a width of the second layer. Additionally, at each of the plurality of spaced locations, the gaps may result in the formation of one or more fusible elements of the electrically conductive material spanning between an adjacent set of longitudinally spaced segments of the electrically conductive material. Each fusible element may provide electrical continuity between the adjacent set of longitudinally spaced segment and may further have a minimum fusing current between 0.001 amperes and 0.500 amperes.

A fire-resistant in-building wireless communication system designed to maintain functionality under extreme conditions, including temperatures exceeding 1850 F. and water spray exposure. The system includes a dual wire assembly comprising a first and second wire separated by a predetermined distance to transmit radio frequency (RF) signals. The wires are formed from high-temperature resistant materials, such as copper or metallic alloys, and are secured by separator nodes made of fireproof materials like furnace cement or silica cement. The system includes a high-temperature resistant antenna for RF signal radiation, supported by an antenna support node, and tensioned via pivot nodes equipped with adjustable mechanisms. The assembly is further encapsulated by a fire-resistant wire wrap to prevent electrical shorts and interference.
