It's quite a job to get closer to wire speed with 802.11ax still... Let's assume dual spatial streams and devices that not quite support anything past U-NII-1.

This leaves us with 5x20MHz spectrum and while being good netizens we'll leave some of that free for others (and ourselves), so we use just 40Mhz of that.

With the tightest modulation and guard interval even, theoretically, we will acheive at best 573.6Mbit/s simplex and not the best of latency and jitter.

I'm not saying that 802.11ax is not worth the money. I am however saying that getting closer to garanteed Full Duplex 1Gbit/s is hard. And I still have 2.4Ghz-only -devices still in daily use.
