SXTsq 5 ax simple bridge 180m

RouterOS Wireless Networking
1

Hello,

Very simple setup, one SXTsq 5 ax as AP, other SXTsq 5 ax as client-bridge 180m away, perfect LOS.

I made simple cfg1, set SSID, country superchannel, band 5GHz AX, chann.width 20/40/80, freq 2300-75000

THE signal are -70 at best !!!!!!!!!!!!!!!

there is SXT SA5 ac near, that I see -40, as expected to this range

Are there something I misconfigured? Or is this joke and new bright future of WISP hardware?

Thanks.

Cool story, can you export working config for review

experience report: Nv2 compatibility - #7 by rextended

For sure, 75GHz...

5

I'm expecting -70 at 1000m, -50 at 180m... with SXTsq 5 ax @ 6Mbps

6

Expecting or experiencing???

same for CPE, except mode client-bridge

It's math, so I expect it.
As for work, however, I'm experiencing.

(and two:)
What are you writing? The device doesn't work at 75GHz... and not even to 2,4GHz

10

its just range what channels can radio choose, obviously it chooses 5180-5880 or smth

So I wonder, what is going on? :slight_smile:

NGL, I avoided using sxtsq ax on a new project and went with sxtsq ac as sxtsq ax is a new device. Can you change wireless from AX to AC only on both devices and see if signal improves? RouterOS 7.24beta1 is installed on device, I don’t see any posts with issues on this OS. Can you change country=Superchannel to your actual country

Try first non-edge channels @ 20MHz, then find manually the best.
auto-frequency do not work well as expected...

AC doesn't change anything

this is 150m distance

country is superchannel

15

-65???

At 150 meters I would expect (never mind how) -55,
-60 respecting local regulation...

16

I don't intervene here anymore (excpt whn ctd), too many strange things.

17

5240MHz gives -57

somewhat better :slight_smile: but nothing compared to older AC products

try for yourself :slight_smile:

Have you done bandwidth tests over the links? If the links stay solid with no disconnects lock them in and be happy :stuck_out_tongue:

I will do that. For now with your help it is some kind usable. But clearly not right. with these figures I cannot imagine link more then 200m, because signal will be -80 and not working. I have UBN* loco ac 350m link 20db gain signal -49

how to explain such low signal for mikrotik?
