This is monumental - I claim every major advance in communication technology immediately precedes a major progress for society. This will make the 'Internet' truly global and ubiquitous. So excited for the developing world.
Careful. Major advances in communication technology also precede major military upsets. Only the victors labelled those as progress.

A) A thin tarp or pant etc could obscure the shape without blocking radio waves. B) These things need to transmit up, so you can reasonably block most signals in other directions. Aircraft would work, but again not cheap. The real issue is more on the human side and network monitoring. Lots of encrypted network traffic to a ransom location would be suspect. PS: For once tinfoil might actually be useful vs government…
A) all radome materials have some degree of loss. Ideally you want no loss at all. The path loss in higher than 10GHz frequencies to LEO is already extreme. B) not just up but to the sides and toward the horizon as well. This will be a non moving phased array antenna that can talk to two LEO satellites moving across the sky at the same time. I predict that any reasonable amount of blockage to the sides will not be a…
B) Depends on how many satellites are in the constellation. Ideally you want a lot of them as there is vastly more atmosphere the lower your angle to the horizon.
C) detectable at say 50 feet sure, but a signal you can detect from 10+ miles in a van doing 60mph without a lot of false positives is another story.

I'm from a third world country(Sri Lanka) and we already have really cheap LTE access, the connection I'm using right now(on my phone) gives me something like 1GB/1.5USD at average 4MBPS. What sucks is the speed and reliability, speed always fluctuate and even though most of the island is now covered by 3G, LTE is not a given. It has been improving a lot though because we have relatively good competition between mobi…
I don’t know if I would call that cheap. Right now I consume 300GB per month on aversge, and that’s just my home use. I get 150Mbps for $98 per month. St your rates, that 300GB would cost $450 per month, though I do realize I would consume less on a slower connection.

If you really want to get excited for the developing world - research the number of new submarine fiber cables that have connected coastal cities in many major African nations in the time frame from 2004 to 2018. That's a lot of capacity. Now a big part of the problem is outdated regulatory regimes and government-controlled telecoms that are keeping prices artificially high, and keeping out competition in the 4G/LTE…

This is where I would love my old Samsung's "ultra power saving" mode. Nothing but calls and texting on a black and white screen. Almost a week of battery life.
What phone is that?

Probably not really a factor. Countries were the government wants to control the Internet or communications in general will outlaw the possession of sat-com equipment if they can't get adequate control over it through some other means.
Just like India does.

Really, the audience for this are ships and other remote regions, not anyplace that has a road going to it.

Sri Lanka coverage: http://www.airtel.lk/coverage-map.html Bamako (capital of Mali) coverage: https://www.orange.com/en/Group/Orange-in-the-world/countrie...
The uncovered area of Mali is probably 5-8 times the size of Sri Lanka.
