I don't have satellite internet service so am restricted to cell phone (high speed), wi-fi or laundry room internet service.
I have been very satisfied with my cell phone service finding coverage in most places to which we travel. Moab is one exception and I rely on the kindliness of our framily with satellite service providing wi-fi access. However, I find that, due to the latency of satellite transmission, there is little difference in speed between my cell phone and satellite/wi-f for most of my usesi. At QZ, I normally use the cell phone and only tie into wi-fi if I will be doing extensive web surfing or downloading in order to free up my phone. Since Sprint doesn't charge me by the minute or kb I do have the opportunity to stay on it all day if needed. It will be interesting to see how our new forum site works with satellite/wi-fi at Moab and whether it will overcome some of the latency problem.
In campgrounds, I have found wi-fi reception variable and iffy. It is also somewhat dependant upon the service the campground is using to access the internet; DSL, cable or T-1. When parked in a good reception area, faster broadband service such as cable or T-1 gives a much more satisfying experience.
