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

17 > We have the following constraint for AP1:
18 > 1.05/r_STA1 * rho_STA1 + 1.05/r_STA2 * rho_2 <= 1 (1.05 instead of 1 because of cross-traffic)
19 > We should thus have:
20 > mu = 1 / [ 1/2 * 1.05/54Mbps + 1.05/54Mbps ] = 51428571
21 > simulation_time = 1000*8 / [ mu / 2 ] = 0.0003111111s
