+> TEST: Send from a station to a node on the wired network after the AP.
+> ----------------------------------------------------------------------
+> Since AP1 is the limiting link, we have the following constraint for AP1:
+> 1.05/r_STA1 * rho_STA1 <= 1   (1.05 instead of 1 because of cross-traffic)
+> We should thus have:
+>   mu = 1 / [ 1/1 * 1.05/54Mbps ] = 51428571
+>   simulation_time = 1000*8 / mu = 0.0001555556s (rounded to 0.000156s in SimGrid)
+> Actual result: Sending 1000 bytes from 'Station 1' to 'NODE1' takes 0.000156 seconds.
+>

+> TEST: Send from a station to another station on the same AP.
