Current wireless bands remain consistent due to established standards and compatibility needs.

I believe this technology is now common among cellular providers. I don’t remember cordless phones using it in the US either. I think they still rely on 900Mhz, 2.4 GHz and 5.8Ghz frequencies. Since Wi-Fi is a worldwide standard, they can only operate on bands that countries agree on, which would make regional customization difficult and compliance challenging.
It seems like you were considering cordless phones and their frequency range, noting that some countries restrict certain channels in WiFi standards.
