Thread: Channel Difference

  1. #1

    Default Channel Difference

    I am new to inSSIDer, and am using it because my project is related to wireless networks.
    I've been using inSSIDer on my laptop and a wifi analyzer app on my mobile phone to detect the channels used.

    However, I got this different result by checking my own router.
    From inSSIDer, my network channel is 1+5, but from the mobile phone app, it shows channel 3.
    Why is that so?

    Sorry if it's a noobie question.

    802.11N access points can use a 40MHz channel mode to achieve high throughput (the advertised 150-300Mbps). This requires using 2 normal channels, the primary and a secondary (1 + 5 being channel 1 is the primary, while 5 is the secondary). This is explained more here:

    As for the phone showing channel 3, the phone is reporting the 'center' channel number. The center channel is the channel that is between the primary and secondary channels.

    Thanks for the explanation! I read that post before asking this question. I am actually just curious about the result of my mobile phone app.

    thanks again!
