Wireless alternatives

I live alone and my wired connection is fine, but I've been curious about wireless alternatives. Partly because I move around a lot, partly because I just like understanding how things work.

I came across Wave 1 while looking into fixed wireless and 5G home internet options. Spent a while reading through it trying to understand the realworld differences between the technologies. It got me thinking about how much the "right" setup depends on your building, your neighborhood, your usage.

I work from home doing illustration so a stable connection is pretty much nonnegotiable. Latency during video calls is the thing that kills me most.

Curious if anyone here has switched from a wired setup to fixed wireless or something similar. Was the transition smooth? And how do you even test whether wireless will be reliable enough before committing to a plan?
