With eXtremeRate, improvement of transfer efficiency is assured, other than acceleration inside the range of Annex C standard such as precision improvement of a/D converter and decrease of noise source, S=1/2 system and the new error correcting code (trellis coding) by adopting, (the acceleration of the highest 1Mbps and average 500kbps makes possible).

On the one hand, besides the fact that with eXtremeReach it rises same as C.x and Annex A.ex and descends to zone of direction and lets flow the data of direction, it expands the range of the zone which can possess the control signal, has become d
