Great question. I previously worked in a field where we relied upon mobile connectivity in this region for data collection, most carrier's coverage maps are low-resolution marketing bullshit based on theoretical detail--particularly in that area. That's the blunt observation from firsthand experience, I can probably name off a half-dozen areas where there is no signal to be had at all for miles. How that doesn't make it onto a coverage map is beyond me. Even when I am back in the area these days, there are several spots along highways US-19, US-58, US-23, etc., where calls will drop every single time you travel through the spot. Decent-sized towns have capable signal, but you leave those areas and the population density just doesn't support a carrier's business. I just wish their coverage maps painted a realistic picture.

The geography does pose a problem there. It's my understanding hardware on a cellular tower travels in a vertical beam, in addition to the more commonly understood horizontal beam. Altitude placement of towers is a factor as well. Altitude variance in those jagged mountains and rolling hills make for awful propagation. Radio/signals aren't my trade though, there's definitely somebody on HN who knows the specifics.
