Significance of the value of interference.


Significance of the value of interference.

Ekahau SiteSurvey ver. 4.4.5, I did a site survey and I found a level of interefence equal to -100 dBm or smaller and a level of signal strength equal to -76dBm.
dBm.

In monitoring of the intefaces the values is:

Interference by Channel

1 -128 dBm @ 0 % busy
2 -128 dBm @ 0 % busy
3 -128 dBm @ 0 % busy
4 -128 dBm @ 0 % busy
.
.
.
13 -128 dBm @ 0 % busy


Noise by Channel
1 -97 dBm
2 -97 dBm
3 -97 dBm
4 -97 dBm
.
.
.
13 -97 dBm


When I connected with my adapter and Intel PROSet, the supplicant indicated a level o signal strenght of -66 dBm and interference of -88dBm.


Ok, the adapter was not the same (ekahau with CAB21 Cisco and connectivity with Intel 5100), but why there are these difference of values in particular of interferense?


Regards.
