Managing WiFi with Frequency Selective Structures

If you're interested in how to better confine your WiFi signals then know that there are ways to accomplish that. When you read the research paper, " Research to Demonstrate the Ability of Close-coupled Frequency Selective Structures to Enhance the Spectral Efficiency of Radio Systems in Buildings," (in PDF format) you'll learn that signal propagation can be be limited entirely or switched on and off. In essence the technique uses copper (aluminum works too) along with relatively simply electronic components such as diodes or transistors. The technology is being designed into wallpaper that can readily applied to walls.
