You normally need to add 30-60 db of attenuation to get best throughput
when directly cabling with SMA cables. Please try adding more attenuation.
What firmware are you using on the T1024RDB? Maybe also try using a different
firmware version to see if that helps.
Thanks,

Hi,
Yes, we are doing the testing in an isolation chamber (no attenuators
used), antennas
are connected to RF card via SMA cable. Tx power is 5dBm. we are not suspecting
Lanforge
as it gives required throughput in different WiFi setup.
here Device Under test is T2014 based card.

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,

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.
