Abstract

A method for data transmission includes representing data using at least one impulse based on a ultra wideband impulse, sending the at least one impulse over an electrically conductive guided media, receiving the at least one impulse over the electrically conductive guided media, recovering the data encoded in the at least one impulse after receiving the at least one impulse over the electrically conductive guided media, storing individual bytes of the data recovered from said ultra wideband impulse signals in selectable memory locations of a plurality of buffer memories, each buffer memory for storing a plurality of said bytes, adding header data to outputs of said buffer memories and forming a plurality of variable length packets, and transmitting said plurality of packets in ultra wideband impulse output signals.
