-The above figure shows the wired topology. STA 1 and the AP are suppressed by 50 dB of external attenuation (plus cable loss and 3 dB loss through the power splitter). The same is true for the link between STA 2 and the AP. The link between STA 1 and STA 2, however, involves 100 dB of external attenuation as well as the tens of dB attenuation after leakage between the two input ports of the power splitter.

The same is true for the link between STA 2 and the AP. The link between STA 1 and STA 2, however, involves 100 dB of external attenuation as well as the tens of dB attenuation after leakage between the two input ports of the power splitter. This attenuation is sufficiently large such that neither STA can decode the other's transmissions. Furthermore, it is sufficient attenuation such that neither STA can physically carrier sense each other's transmissions.

  * '''Flow 2:''' Backlogged traffic from STA 2 to AP
 
+In this experiment, we will break up a single trial into three sequential pieces. In the first 30 second phase, we will start Flow 1 all by itself. In the second 30 second phase, we will disable Flow 1 and start Flow 2 by itself. In the third and final 30 second phase, we will enable both Flows 1 and 2. This entire experiment will be performed for both an RTS/CTS disabled case as well as an RTS/CTS enabled case.
