Description Tom Henderson 2016-09-08 14:27:36 UTC

This is a reminder to look into an issue reported by a user:

For ConstantRateWifiManager,saying HtMcs7 resulted in (MCS 7) VHT PPDUs if the
.SetStandard was VHT, rather than HT PPDUs.

Created attachment 2578 [details]
test program

I'm not sure about the reported problem.  Attached program configures an 11ac BSS and sets the data rate to HtMcs7.  I observe single MPDUs as non-aggregate.  If I change to:
  StringValue DataRate = StringValue ("VhtMcs7");
I observe VHT single MPDUs within an A-MPDU.

Comment 2 sebastien.deronne 2016-10-02 11:13:14 UTC

Running the attached script with ns-3-dev works fine, I see HT PPDUs being sent as expected. Bug should be rejected...

This looks like the expected behavior, aggregation is not used since there is always maximum one packet in the queue during the simulation.

Bug rejected, script behaves as expected
