re: "Since speed of light cannot be increased, we must kill distance." Propagation velocity does vary based on material properties of the medium. The propagation velocity, as a percent of the "speed of light in vacuum" is highest for wireless, lowest for fiber, and coaxial cable is in between. Roughly, (where c= speed of light in vacuum): wireless: 98% of c coax cable: 87% of c fiber: 68% of c Your homework assignment is ;o)... If the transit time of the signal through the transport medium is so important as you are implying (the propagation velocity can be increased), why don't the HFT systems instead use wireless (30% faster than fiber) or coax (19% faster)?
