LANforge is going to be running a modified driver and firmware, though likely
it is no worse at performance in this case than stock code.

What is the device under test?

And, are you in an isolation chamber, using SMA cables, attenuation, etc?

There are lots of things that can impact wifi throughput so you have to provide
lots more details in order for anyone to understand why the throughput might be
less than expected.

And if it is specific to LANforge, please send email to supp...@candelatech.com

Thanks,
Ben

Hi,
     I didnt try with ath9k drivers on the same setup.

     we are using  WiFi capacity test tool on Lanforge to test the performance, 
this will
generate the traffic. we are selecting the UDP protocol (packet - 1472 Bytes).

     As per TEC spec. required data rates are given below.

     Mode         Asso. rate         Throughput

802.11a            54 Mbps             28 Mbps

802.11g            54 Mbps             28 Mbps

     But we are getting only 26-27Mbps, how to improve this throughput ?

     [TEC(Telecommunication Engineering Centre, Govt. India) is a technical 
body,
prepares specification of common Telecom standards.]

Out of curiosity, does ath9k perform at the required rates in a similar
setup?

Sending tcp, udp, or some other protocol?  How are you generating the
traffic?

Hi,

      When we are testing 802.11 a/g mode throughput measurements on
T1024RDB ( we used
kernel-3.12; ath10k drivers backported from 4.4;hostapd 2.5 for 11AC
support), then we
are getting 26-27 Mbps , which is not meeting the required TEC
specification (which is
~28 Mbps). How can we increase the throughput in these modes.

       Can you please help on this.
