I have a WiFi access point at my place.
I used this App - WiFi Analyzer App to check the signal strength and the channels which I am using.
While using, I had this question which google was not able to provide an answer.
If you check the above image - Mine is the Last peak occupying channels 9-13.
I am connecting only my mobile to my WiFi. So, why is my WiFi using 4 channels (From Channel 9 to Channel 13) to transmit the information to my connected mobile device?
Or in general, what does the width of the channels actually indicate? If I connect 5 or more devices to my WiFi access point, does the WiFi access point use more channels?
