You can search in the forum to get more detailed information aboit 'noise-floor' values, e.g. the particular topic gives exact answer, what does 'noise-floor' means:
http://forum.mikrotik.com//viewtopic.ph ... loor#33302

If you are talking about 'noise-floor-threshold' configuration, most likely value is not actual to your wireless cards, some older chipsets supported this option.

But Sergejs , high noise-floor is better then low ? ( actually we have on a BTS -86dbm and on other -119/-123 )

The first one have a senao 8602FCC+Plus , the second a Zcom H622 ( 23db of power )


Thank's

Less noise is always better, so a low noise floor is better than a high one...

So , a BTS with -120 Noise Floor is better than a BTS with -90 Noise floor .. Correct ? :-)

Yes, you are right, but this is not MT, this is basic physics...

:lol:

If you start from zero (0), and continue in a negative direction (towards -90) then continue towards -120, then -90 is a higher value than -120, capish?

eg:

High number
5
4
3
2
1
0
-1
-2
-3
-4
.
.
.
-90..... [noise here is higher (louder) than noise below]
.
.
.
-120.... [noise here is not so loud]
.
low number

:shock:

Yes , I know that. Only for remark.

We have a lot of problem with MT . We have a real scenario in dense urban coverage.

So , in next days , i post our experience and our problems.


Ciao

You have to be more specific about problems. I think posts 'we have a lot of problems' are useless without problem detailed description, as there might a lot of reasons not connected with MikroTik, that can cause your issues.
