Most of this doesn't answer your question some of it does My brother lives in an area where there isn't any DSL service
he has a AT&T 4G mifi card normal cost is $60 a month
He worked for phone company and gets a huge discount house phone, cell phone & mifi card $80 a month.
when camping and sometimes when I'm in a motel/hotel that has weak wifi signal I use my ALFA mifi dongle
it comes with a small 6 inch antenna but I also have a 18 inch yagi beam antenna when the beam antenna
is hooked up and running I can pull in signals from miles away.
from my house here at the lake it is about 5 miles using the road to town and McDonalds but about 2 miles line of sight
I am able to use their wifi from my house I don't because it is to slow, but the ALFA & beam comes in handy when camping
for weak signals but out in the boondocks where no one has wifi then I can tether my phone I've only done this once.
