10Mhz channel on 5GHZ

Thu Mar 18, 2021 8:03 pm

Hello Guys,

Is it possible to setup 10Mhz Channel width on 5Ghz range ? I am getting an error. Any help is appreciated.

Thanks,

Ehm...why?
And...what error?

I think you would have to select 10MHz as Control Channel and disable extension channels, but still...why?

If you're using Mikrotik AC gear then you're out of luck, 20MHz is the smallest channel bandwidth possible.

That is unfortunately correct... the older N equipment can do 10 and even 5 MHz channels, but AC devices do only 20 MHz and above.
Apparently it is a limitation of the chip that is used.
It is unfortunate, because for long distance links a smaller bandwidth (of course with lower speed) is often better.

Is this even compatible with the 802.11n standards, as most client devices I know of only work with 20MHz channels, or is it a Mikrotik-only feature?

Usually N type devices can select those 5 or 10 MHz channels without problems.
And on some other manufacturer's AC devices it is also possible to select 10 MHz.
The typical indoor WiFi router and the typical WiFi client (e.g. phone or laptop) cannot do this, which is another reason to sometimes use it on links.
