And in those days, you'd be lucky if you can sustain 2Mbps on wi-fi.
Today, I can do several-hundred Mbps on all my 802.11ac devices in my
house (up to 867Mbps to my laptop and wireless-USB-adapter-equipped
desktop). Even if we had to compromise this somewhat for massive, dense
deployment in crowded locations within busy cities, the utility would
still be miles ahead of what we got from Fast-E 25 years ago.
