Securing networks with new Teijin sheet
At a time when the communications trend is headed away from one-dimensional cable and towards three-dimensional wireless, Japan’s Teijin Fibers has developed a unique medium for two-dimensional communication. But this is hardly a step backwards, the company says. Conventional one-dimensional communication transmits information through wires, which offers high security but requires complicated wiring, whereas three-dimensional communication uses wireless signals for mobile communication, which poses security risks and occasional problems with interference because signals are transmitted through open space. Teijin’s new two-dimensional communication sheet, called the Cell Form, employs an entirely new technology that confines electromagnetic waves to a cell within and around a special thin sheet. Connection between the sheet and a laptop equipped for wireless local area networks (WLANs) is established when the PC is placed on the sheet. The sheet can be several metres long and accommodate multiple PCs at the same time.
