[Hidden-tech] AT&T Mobile Hotspot

[ussailis at shaysnet.com]

That's a problem in such a largely unpopulated country. We can't compare
here to Europe, which in many of the more prosperous regions, has a much
higher population density.

The problem is simple: we either use WiFi (or some variant) or the cell
phone network. In the cases of WiFi we are limited to a one watt
transmission (actually most WiFi card set-ups are around 0.1 watt, a rare
few provide 0.2 watts). One doesn't expect the range of a 0.2 watt
transmitter to be all that far. We can make up for this by having many "hot
spots," but that requires "users."

The cell phone frequencies are owned by the cell companies. They have a
vested interest in expending infrastructure money where revenue can be
gained. This is usually not in the middle of the desert, or some of the
hills of W. MA.

So it's a satellite, or tethered to a phone line, as my son is in Ashfield
near Hawley.

PS If you want a laugh, look up Greenvale, Nova Scotia. I have the old
family farm right where Google maps says Greenvale is. Population = 0
humans. Many deer, some bear, fish, etc. Even a fisher was spotted there.
And I get fine cell service! Of course the TransCanada Hwy isn't all that
far away.

I'm very curious about this as well. I am headed to Yellowstone and 
grand Canyon and was trying to figure out if I would be able to get a 
mobile hot spot and find activities along the way? Has anyone tried 
these in the Great West?  I hope it's okay to jump into this question, 
sorry if it's not.
