hi,

in Troubleshooting how can the Signal to noise and Noise floor affect the signal , how can we use them to get better signal

and which value is the minum for them

and thanks in advanced .

2

What frequency u use?

For better performance try this steps

Try another channel.

Change polarisation of the antenna

hi,

i use the 5730 MHz , so i need to know more details about Noise Floor and Signal to noise ( which value better )

thanks for your reply

Signal to noise:how more the number is how better the quality from your link.


Example good

signal strenght= -53
nois floor= -107 how more weaker the signal how better -107 is weak
Signal to noise = -54
you left signal -54 over to the -107 noise floor
This is excelent for good performance
-107 is much weaker than the signal-53.
Signal to noise (here -54) is the difference between-107 (the noise floor) and-53 (the signal strength)
the more the difference between those two how better the link quality




Example not good
signal stretght= -80
noise floor = -90
Signal to noise = -10

I hope youre understand me

thanks plisken :sunglasses:

If you want give me karma pleace i apreciate this verry match

tell me in troubleshooting Interference what technique do you use ? any tools ? any advice ?

Hey Rihan Tnx.

If i have to match interference from other devices do I change the antenna by polarization.
The default access points have vertically polarized antennas.
If you do then your antenna polarization changed to horizontal can solve this much.

thanks , but from where i can change the polarisation i checked up in the wireless interface of my SXT and there’s no polarisation parametre
thanks in advanced for all your help friend

As far as I can remember SXT is a dual polarity device (two builtin antennas in a single dish) … chain 0 is vertical and chain 1 is horizontal or vice versa not really sure which is which … someone correct me if I’m wrong …

This is correct
