Widening UWB System Coverage Zone by Repeaters-Regenerators

The Federal Communications Commission (FCC) of the USA has limited communication coverage zone for pulse UWB systems by implementing power density mask on all transmitting devices. As result the UWB coverage area is not exceed a hundred meters. But it is possible to increase this area, still fulfilling the FCC limits, by adding one or more UWB repeaters around or along the path toward a destination receiver(s). The paper deals with the idea of such repeaters-regenerators and their implementations
