A method and apparatus for remotely detecting, locating, and identifying chemicals and chemical compounds through optically opaque materials. The base and emitter contacts are formed to have sub-lithographic feature sizes. , is transmitted from a dispatching terminal to a dispatching information server. This TR technique is combined with the DH multiple access technique to create a UWB communications scheme that has a greater multiple access capacity than does the UWB TR technique by itself. Subsequently, the metadata at the second volume is processed to reflect the virtual machines which were not migrated.
