COMM (communication) while camping or boondocking

I built a live to laptop GIS system with live GEOJSON feed from the FCC (A and B Block CGSA) we take on the road:

...that populates my map with the absolute latest tower and coverage polygons. In addition, I have live feeds from various National weather agencies to overlay into my cell coverage map, that I can use to analyse any possibility of cell tower disruption, or cell sig disruption (this is today's the live national weather, satellite, tornadic vectors, warnings, rotation tracks, in my cell map, linked above)...(heavy rains, air-borne ice (hail), snow storms, lightning, tornado killing a tower, etc...)

Note the grayed-out coverage areas in the East (very, very few); and in the West (very, very many). Look at northern Maine (the Mount Katahdin area) where the no coverage at all is located...
