 == Experiment 2: Symmetric with Hidden Stations ==
 
+In this second experiment, we modify the attenuation values in the experimental setup such that each flow sees the same path loss as the first experiment, but the path loss between the two STA nodes is dramatically larger. Topologically speaking, this is an extreme hidden node problem: STA 1 and STA 2 can each "see" the AP, but they cannot see one another.

+=== Performance of Simultaneous Flows ===

+The per-flow isolated throughputs are identical to the first experiment, so they will not be re-presented here for brevity. Instead, we jump directly to the case where all four flows are activated simultaneously.
