FWIW I'm bummed it didn't work out. I had a WiMax phone and even with the spotty coverage, back then (~2012?) my speeds were as good as my current broadband speeds (>200 Mbps) which was phenomenal for sprint. I even considered getting a dedicated WiMax internet provider at the time. Amazing how fast that came and went!
I had WiMax from Clearwire. It was really epic. The dongle on my laptop delivered speeds that weren't even available wired at the time. I used it in Seattle, Phoenix, Chicago, Newark, and a few other cities, and coverage wasn't bad at all.
The only difficulty was that it had a hard time penetrating buildings. In my apartments, I could get 1-2 Mbps anywhere. But if I moved the modem into a window it was more like 25-75 Mbps.
I hope that some day 5G will be as good as WiMax was.
I had one too and the enormous drawbacks of WiMAX became apparent: go deep enough into a building and the signal gets spotty fast. WiMAX may work well for fast wireless internet to thin-walled homes, but it just doesn't work as well as a mobile technology.
