You'd be surprised where in the USA has at least one viable last mile terrestrial WISP. I can think of a few parts of Idaho where you would think nothing exists, but you can get 25 Mbps x 10 Mbps service from a competently run small ISP, by point to multipoint 5150-5850 MHz band equipment.

But there are also vast areas of Idaho too sparsely populated to support any WISP at all, where you'll see cheap consumer grade VSAT stuck to the sides of peoples' houses.

This is true, I used a wisp for 10 years in Montana. However in my valley there are many residents who don't have the required line of sight to the wisp providers tower/equipment for service due to trees or hills blocking. Their only current solution is 4g or satellite.

I have been having challenges with this. I want to move to Wyoming and get a decent amount of land, but I also want gigabit internet. What I just described appears to be a unicorn. I've already had ISPs laugh at me. Realtors and their websites are no help in this area.

I have a great deal of sympathy with this. There's so many beautiful low cost of living/low cost of real estate locations in the US and Canadian west, but the best locations are also places where you're looking at no Internet, off-grid solar/wind power, etc.

Depending on where you are looking, and what your budget is, and your level of motivation you might look into seeing how difficult it would be to build your own point to point link back to a place where you can get 'real' internet.

I also want symmetric gigabit but in a very rural location I might be totally satisfied with 40 Mbps down x 15 Mbps up, if it was sufficiently reliable and good quality (overall uptime in a year, latency, jitter, etc).

There is a great deal that can be done with sets of equipment like a 90cm high performance dual polarity shielded dish (ALG or Jirous or similar), ubnt AF5XHD radios, etc. Perhaps for less than $10k all-in you might be able to build your own link to reach the nearest WISP or terrestrial connectivity. Entirely depending on how remote you are and terrain.

I've thought about this as well. It would cost more, but I could get a really small house at the edge of a city, set up a Ubiquity tower, maybe licensed, and have my own radio link. I managed these links in the military and bad weather aside, they were decent. I too would be ok with 40/15 myself, but family members need more. I might catch some flak for putting up a small tower. I would like to avoid the commercial wireless solutions so that I could have more control over jitter/latency.
