If a user installs a ROM that interferes with radio frequencies
Do any “ROMs” or linuxes do this? Seems like you could get an “illegal USB bluetooth/wifi dongle” for shenanigans purposes instead. This all seems like such a pointless distraction that can only be to ensure that manufacturer backdoors are ensured as unescapable.

I have never installed a ROM that touched the radio.
In fact most ROMs I’ve used warned against touching the radio because of the risk of damaging the device.

sorry for Gemini link to prompt below, but google itself doesn’t provide any top page links to answering the question, or questions about “software wifi to radio conversion”. GrapheneOS does not provide the functionality. Seems like only process to transmit/receive at a different band is to use hardware that bridges from wifi signal to radio signal.
It is generally not possible to directly modify the WiFi frequency on a smartphone to an arbitrary frequency. Smartphones are designed to operate within the standard WiFi frequency bands (2.4 GHz and 5 GHz) and their corresponding channels. While you can influence which band your phone connects to (e.g., prioritizing 5 GHz for faster speeds), you can’t arbitrarily set the frequency. Why you can’t set an arbitrary frequency: Hardware limitations: Smartphones are built with hardware that supports specific frequency ranges (2.4 GHz and 5 GHz in most cases). Protocol compliance: WiFi communication relies on specific protocols (like 802.11 a/b/g/n/ac/ax) that are tied to these standard frequency bands. Router configuration: While you can configure your router to broadcast different SSIDs for each band (e.g., “MyWiFi_2.4GHz” and “MyWiFi_5GHz”), the phone’s connection is still limited to the supported frequencies. What you CAN do: Prioritize a band: You can influence which band your phone connects to by adjusting settings on the phone (if available) or by configuring your router to have separate SSIDs for each band. Choose the right band: For faster speeds, prioritize the 5 GHz band when it’s available. For better range and wall penetration, the 2.4 GHz band is better. Optimize router settings: Ensure your router is set up to broadcast on the desired bands and consider channel selection for optimal performance. In short, while you can influence the band your phone connects to, you cannot arbitrarily set the WiFi frequency on your smartphone.
After RTFAing, this seems to be Samsung just using an excuse to lock down their phone, rather than any specific order from EU telling them to.
