A Comprehensive Overview and Characterization of Wireless Channels for Networked Robotic and Control Systems

Figure 6

Underlying dynamics of the received signal power across route 1 of Figure 5 and for the transmitter at location #1. The blue curve is the measured received power which exhibits small-scale fading. By averaging locally over small-scale variations, the underlying shadowing variations can be seen (gray). The average of the shadowing variations then follows the distance-dependent path loss curve (dashed line).
