Need to downgrade Wifi card frequency (5GHz/2.4GHz) to 500 to 550MHz

Hi all,

I have a requirement of downgrading Wifi bands (5GHz/2.4GHz) to 500-550MHz frequency on Mikrotik RBM33G+Wifi Transceiver cards.
We would be using OpenWrt Chaos Calmer for flashing.

Can someone please help on this query.

This version is ancient and no longer supported.

Please upgrade to a modern version of OpenWrt (23.05.2 is current).

a) chaos calmer is not supported anymore, hasn't been for 8 years
b) modifying or changing wireless parameters outside their FCC/ ETSI/ MKK regulations is illegal in most jurisdictions - nor possible without hardware modifications, for which you need an RF lab, your own modified PCB (for which you will need cooperation from the chipset vendor, for certification alone), so if you do have to ask here, you won't be able to do it (nor be legally allowed to).

That is cell phone spectrum.

Why do you need cell phone spectrum?

closing this topic because of the illegal nature of the modifications requested as well as the fact that the version of OpenWrt is no longer supported.
