I understand that the higher the SNR, the better. But I am using inSSIDer, and it only reports signal strength in DBM.
So my plan is to use inSSIDER to work through all 11 channels at 2.4ghz to try and find the channel with the best DBM reading.
But, does changing the channel affect the noise level, or is noise level constant (from devices such as phones, baby monitors etc)?
Because if noise is constant, then all I need to do is find the best DBM. But if noise changes with a channel change, then even if I find the channel with the best DBM, it may have more noise, with the net result of actually a worse signal (if this makes sense).
So basically, is noise constant or does it change with the channel? If it changes, are there any free PC programs that can provide me with a SNR reading.
Thanks all!
