AR9380 - laboratory tests

World record? :smiley:
I hope you like it

MT Team:
Can you make better power control for AR93xx cards? Now it works only in all-rates-fixed mode, and it’s a problem for link stability
Are you planning to support QCA9880 or other 802.11ac chipsets from Qualcomm?

Which kind of HW?

Giuseppe

Check specification at the bootom of this site:
http://www.cyberbajt.pl/cms.php?get=produkt,4334

4

for those chipset cards only all-rates-fixed is working.
On what distance you get such results?

5

Why using MiniPCI express? Is there any harware limitation with MiniPCI?

6

Is this software or hardware limitation?

This is laboratory test. In outdoor test results are 10-20% worse.

7

Have you found any 3x3 card for MiniPCI? AR9380/AR9390 works only with MiniPCI-Ex

8

for example

All the those cards have only 2 chains, so MCS-15 only and 300Mbps.

10

Look you good? All these cards are 3x3 mimo

11

They aren’t full 3x3 MIMO. They are 2T3R, AR9160 is 2-chain chipset.

12

Data Rates: Legacy 802.11a/b/g (1-54Mbps), 802.11n (up to 300Mbps)

13

2T3R cards, can they actually receive @ 450Mbps?

They actually TX/RX over all three chains but only two streams, correct?

14

OK, my mistake :slight_smile: Does anyone 3x3 sector antenas deployed in real production?

15

RF-elements shown 3x3 sector at MUM. Gigaeter is a panel antenna, not a sector.

16

What with my question about new chipsets support?

17

outdoor test
distance 35km
antennas on both ends rocket dish 5g34 (V/H polar.) + 28dbi panel antenna in slant polar.
card - http://www.compex.com.sg/fullDescription.aspx?pID=132 with ar9390 chipset
environment full of noise
tested with nv2, nstreme , 20MHz channel , 40MHz channel, fixed data rates, default data rates, all tx-power mode

best result 90Mbps half duplex
any help? uldis, normis?

Can you show us:

Important question: how do you connect the pigtails to the cards? Please describe the order in which have you connected pigtails?
I see from screens, that you have problems with signal level. Signals should me similiar.

19

wireless card have basic setup, most is default and experimented with every combinaton of frequency, nv2 , nstreme , data-rates, tx-power.
ch0 is vertical polarization of RocketDish 34dbi
ch1 is horisontal polarization of Rocket Dish 34dBi
ch2 is +45° slant polarization of panel antenna 28dBi

reason for the asymmetric signal is frequency 5000 MHz , for freq. 5500 signal levels rx/tx are almost identical
in one situation i had 135Mbps but not stable

20

Connections are correct. If in 5500 freq signals are identical, so I think you had to install slant antennas in good positions.
What you may try:

  • set data rates only for MCS16-20
  • for testing use simple 802.11 and check BER on the link (you have poor CCQ)
  • best result I have with nstreme with dynamic size, but you can try nv2 too
  • try to find some channel near 5500Mhz - look at CCQ & Signal strength parameter when you decide which freq is better

Maybe I could I look at your link directly (via net of course). My priv conntact: czolo[at]o2[no_spam].pl
