testing 5/10mhz on the nmp-8602

Is anyone using 5 or 10 mhz?
What speeds are you getting with 5 and 10mhz?
What cards have you used to do 5 and 10 mhz?

I’m asking because I’m getting some odd speeds with 5 and 10mhz. So I thought I would see how you all are making out with it.

Hey, GD3
Can you you post your numbers:o) :smiley:

Jober here are my results..

band 2462mhz:

5mhz udp receive 8.0mbps, udp send 8.1mbps, udp both 3.9mbps
5mhz tcp receive 6.1mbps, tcp send 6.2mbps, tcp both 3.4mbps

10mhz udp receive 15.1mbps, udp send 15.9mbps, udp both 7.7 mbps
10mhz tcp receive 10.9mbps, tcp send 10.8mbps, tcp both 6.4mbps


band 5180mhz:

5mhz udp receive 7.4mbps, udp send 7.9mbps, udp both 4.0mbps
5mhz tcp receive 6.4mbps, tcp send 6.3mbps, tcp both 3.5mbps

10mhz udp receive 14.6mbps, udp send 16.1mbps, udp both 7.9mbps
10mhz tcp receive 11.4mbps, tcp send 11.2mbps, tcp both 6.4mbps

20mhz udp receive 22.1mbps, udp send 19.5mbps, udp both 11.2tx/12.7rx
20mhz tcp receive 11.9mbps, tcp send 11.4mbps, tcp both 5.9tx/6.0rx

All tests done with 2 RB112’s. One was acting as btest server and other as btest client.
single static ip configured on the wlan interface on each board..
no firewall rules, nat, bridges, routes or anything else configured.
wlan cards are configured all to default settings except for the band and frequency. Tx power set to card defaults.

I did notice when I turned up the tx power to 26dBm the speeds became erratic, I figured it has to do with the fact that I only have pigtails connected without antenna’s..

During all of the tests the cpu on the rb112’s was staying at 100%. If I get a chance later today I’ll try the tests agian with RB532’s..

edit:
tests were performed using 2.9.23..

I forgot to do the 2.4ghz test at the full 20mhz channels..


at 2.4ghz-only-G

20mhz udp receive 21.8mbps, 13.7mbps send, 8.8mbps
20mhz tcp receive 12.2mbps, 9.7mbps, 5.6mbps

jober,

I ran a similar test a few months ago with 2 RB532a boards and CM9 cards…just wanted to post for reference as these are just slightly higher than the rb112 tests posted.

  • 2 x RB532a with 1 CM9 each
  • Tests were AP to AP (which will slow things down)
  • Radio mode = ap-bridge with wds (static)
  • 5260MHz indoors with ~ -50dB signal
  • ROS 2.9.17

20MHz channel:
TCP receive = ~18Mb
UDP receive = ~29Mb

10MHz channel:
TCP Receive = ~12.5Mb
UDP Receive = ~15.5Mb

5MHz channel:
TCP Receive = ~6.5Mb
UDP Receive = ~8.5Mb

Interestingly, running this test with PCs on both ends, my results were only about 10% higher, but I ran these later and didn’t record them. I still don’t understand how MT is getting the results they post with RB112.

Gerard, I’d be interested to see what kind of results you get with your RB523 boards.
