A method of manufacturing a superconducting wire includes the step of drawing a wire formed by coating raw material powder for a superconductor with a metal, the step of first rolling rolling a multifilamentary wire after the step of drawing, and the step of first sintering sintering the multifilamentary wire 1 after the step of the first rolling. The nano-porous gas diffusion media of the invention is produced using photolithographic techniques to create a solid substrate comprising a plurality of nano-scale pores or holes that allow for the diffusion or exchange of molecules, gases, andor liquids through the substrate. The technique may be used in data communications devices such as those in wireless local area networks. In a third aspect if such a patent or sequence is identified, a normal frame is inserted in the pattern sequence replacing a compressed mode frame.
