The 5Ghz wifi is going to be basically unusable if everyone implements the new rules correctly, like Huawei seems to have done.
There is an article on MIUI forum about how 5GHz wifi has interfered with European weather radar.
My pocket router will spend a whole minute checking frequencies every time it thinks it has seen a weather radar signal, before it starts working again.
This is what every hotspot is supposed to do, apparently.
However, the 2.4Ghz wifi should work as before, as far as I have seen.
