Standard latitude modems have always been hindered by the bandwidth they are appropriateed to use. Standard vocalize grade phone lines use the relative frequency spectrum between 0khz and 4khz to stockpile their signal. 33.6 kbps modems packed close to 11 bits of entropy per hertz, a remarkable feat, which is very near the theoretical limit. To allow windy connections modems must use a wider bandwidth.

?Two revolutionary competing technologies are now being developed which use this wideband radical to give computer users the speed they crave. Telephone compa! nies are working(a) on developing a way to use the bill twisted pair copper wires that now connect nearly every home in America to transmit data at high speeds.
