Can somone please explain CCQ?

I’m sure i’m not the only one here who dosnt fully understand what CCQ is and what the value we see in RouterOS actually Means. I’ve come to understand from a few posts in the forum that the Higher the CCQ the Better

But, What is it? What Causes a good wireless link to have low CCQ? etc etc.

Anyone got some time to explain it to us newbies?

There are few topics, where this question is asked, and than answered,
here is documentation description,

Well Im trying to understand it as well, in view of my posting earlier today.

We are all capable reading the manual which says
rx-ccq (read-only: integer: 0..100) - Client Connection Quality - a value in percent that shows how effective the receive bandwidth is used regarding the theoretically maximum available bandwidth. Mostly it depends from an amount of retransmited wireless frames.

So tell us about the part of rx-ccq that is NOT mostly due to retransmitted wireless frames, so that we may apply that new knowledge to our real life problems.

ok guys what about 0% i have one AP it has 0% and no client can connect to it is that means the mpci module is not working ?? or mybe its cabling antenna issue ??please help me on this
