WiFi: Frequencies that map to non-overlapping 2.4 GHz channels 1,6 & 11

  • 772

I'm configuring a wireless router. I know the non-ovelapping channels are 1,6 & 11. However, my router only specifies frequencies that I can select, not channels. What are the frequencies that map to channels 1,6 & 11?

    If you wish to set your wireless radio in your router to a non-overlapping channel, the mapping of frequencies to non-overlapping channels for 2.4GHz is:

    Freq:

    2412  ==> Channel 1

2437  ==> Channel 6

2462  ==> Channel 11

    MikroTik doesn't reference channels in RouterOS but frequencies only, so might help others configuring a router which only describes frequencies set the appropriate value correctly-

  2. we use 1-6-11 non-overlapping channels with 22MHz width DSSS modulation. DSSS modulation is used with channel speed 1-11Mbps. For higher channel speed OFDM modulation is used. OFDM modulation uses only 20MHz so there are 4 non-overlapping channels - 1-5-9-13 (2412-2432-2452-2472). But only if your client devices can use channel 13 :)
