Evaluate Techniques for Penetrating a Shielded Enclosure Using Twisted Pair WireThe aim of this project is to demonstrate techniques for effectively penetrating a radio shielded enclosure using Ethernet cable (CAT-6). This process requires that we measure the shielding performance by means of testing and data orchestration to collect and analyze our data to present observations with different test cases. Each test case would represent a different penetration strategy that utilizes distinctive wire coupling and characteristics (i.e. the type of bulkhead link, the twist of each CAT-6 cable, the shielding type of each CAT-6 cable, and the length of the cable). As the different cable setups are fabricated a prototype evaluation of setup is conducted to measure the signal integrity of our testing configuration. Our signal integrity is measured through the analysis of different parameters found in the prototype evaluation such as RF leakage, impedance mismatch, and decay rate. As each of these data values are effectively collected and analyzed the most effective cable setup is selected based upon its ability to penetrate the shielded enclosure. The testing data is compared in conjunction with the cost of the manufacturing of the prototype wire penetration.
