The power level of adsl is around 20dB...and the power level of vdsl is 14.5dB. Normally as the frequency spectrum increases , power requirement will be more.. but why is it decreasing in vdsl when compared to adsl which has very low frequency spectrum? what will happen if we increase the power of vdsl to 20dB? Is it related to RF interference? Please explain.. Thanks in advance.
