Probably. I mean, I don't even remember what standard my home wifi is on. It works, it's fast enough. Sometimes I think about upgrading the AP but why bother?

3G was up for about 20 years, between roll-out and shutdown.

LTE has been up for 15 year in the US as of now. Chances are it may not be up after another 15 years.
