 //  The following command will display all of the available run-time help options:

-//  By default, the script shows the benefit of the OBSS_PD spatial reuse script:
-//    ./ns3 run wifi-spatial-reuse
-//    Throughput for BSS 1: 6.6468 Mbit/s
-//    Throughput for BSS 2: 6.6672 Mbit/s
+//  According to the Wi-Fi models of ns-3.36 release, throughput with
+//  OBSS PD enabled (--enableObssPd=True) was roughly 6.5 Mbps, and with
+//  it disabled (--enableObssPd=False) was roughly 3.5 Mbps.
 //
-// If one disables the OBSS_PD feature, a lower throughput is obtained per BSS:
-//    ./ns3 run "wifi-spatial-reuse --enableObssPd=0"
-//    Throughput for BSS 1: 5.8692 Mbit/s
-//    Throughput for BSS 2: 5.9364 Mbit/
+//  This difference between those results is because OBSS_PD spatial
+//  reuse enables to ignore transmissions from another BSS when the
+//  received power is below the configured threshold, and therefore
+//  either defer during ongoing transmission or transmit at the same
+//  time.

+//  Note that, by default, this script configures a network using a
+//  channel bandwidth of 20 MHz. Changing this value alone (through
+//  the --channelWidth argument) without properly adjusting other
+//  parameters will void the effect of spatial reuse: since energy is
+//  measured over the 20 MHz primary channel regardless of the channel
+//  width, doubling the transmission bandwidth creates a 3 dB drop in
+//  the measured energy level (i.e., a halving of the measured
+//  energy). Because of this, when using the channelWidth argument
+//  users should also adjust the CCA-ED Thresholds (via --ccaEdTrSta1,
+//  --ccaEdTrSta2, --ccaEdTrAp1, and --ccaEdTrAp2), the Minimum RSSI
+//  for preamble detection (via --minimumRssi), and the OBSS PD
+//  Threshold (via --obssPdThreshold) appropriately. For instance,
+//  this can be accomplished for a channel width of 40 MHz by lowering
+//  all these values by 3 dB compared to their defaults.
+//
+//  In addition, consider that adapting the adjustments shown above
+//  for an 80 MHz bandwidth (using a 6 dB threshold adjustment instead
+//  of 3 dB) will not produce any changes when enableObssPd is enabled
+//  or disabled. The cause for this is the insufficient amount of
+//  traffic that is generated by default in the example: increasing
+//  the bandwidth shortens the frame durations, and lowers the
+//  collision probability. Collisions between BSSs are a necessary
+//  condition to see the improvements brought by spatial reuse, and
+//  thus increasing the amount of generated traffic by setting the
+//  interval argument to a lower value is necessary to see the
+//  benefits of spatial reuse in this scenario. This can, for
+//  instance, be accomplished by setting --interval=0.0001.
