    55Block diagram of the ORBIT Grid domain is shown in Figure 1. It consist of 20 x 20 nodes arranged in the grid (20 rows with 20 nodes each) with spacing of 3 feet.

    14 This subsystem consists of arbitrary waveform generator (Agilent ESG) connected through distribution network to four multi-band antennas located in the four corners of the grid. The distribution network enables control over the attenuation of the individual antenna feed. Using CAWIS, users can inject (among other types of waveforms) AWGN signals into the main ORBIT grid and thus create different topologies.
