After Katrina in south Louisiana land lines were out of service as poles and wires were down, cell phones were out of service due to cell towers and equipment being out. This was not a short term problem. My employer sent a satellite phone for my use. I was only able to connect to one site and then only for a matter of seconds before disconnect. While discussing the problem I was informed that the military had sucked up all the satellite time.
Now when the general population is trying to use this what do you think will happen?

Exciting news indeed! No "dead spots" would be wonderful.

Maybe additional satellites will be deployed to meet demand?
SpaceX is going to be spitting these new bigger satellites into LEO like a PEZ dispenser - they're going to be mass-produced, in the thousands. (Their FCC filing specified up to 30,000 of them.)
Compare that number with the dozen or so satellites currently being used for satellite phone service.

Essentially, a new generation of satellites, bigger, more powerful. Read the link in my other post here.
I can understand receiving a signal from a more powerful satellite, but how is 1/10 of a watt going to "reply"?

Maybe the phone would know if there is no ground service to up the wattage some just to send a text. No streaming movies during the initial roll out.
SpaceX has already done the impossible in so many other areas... this was inevitable.

Same way it gets to a tower... You might think that to talk to a satellite you need lots and lots of power... NOPE. Though I've never done it.. Many Ham radio operators talk to satellites or even the International space station using 5 watts or less...(Yes there are ham radios on the ISS and all the astronauts occupying it are licensed Ambattur radio operators)
Though I've never talked to the ISS. I have heard their transmitter (Full scale) sending what is called Slow Scan TV (30 seconds per frame instead of 30 frames per second) Very strong signal.
You see when it comes to radios.. Height is Might and the Satellites.. they got the height.
Home was where I park it. but alas the.
2005 Damon Intruder 377 Alas declared a total loss
after a semi "nicked" it. Still have the radios

Increasing the receiving gain of the antenna on the satellite reduces the amount of transmit power required from the smartphone.
Having big "ears" makes it easier to "hear" weak signals.

about 52 db of gain I think for the gain on the satellite--if I understood the article I read.
That may be enough for leo.

As mentioned in the Ars Technica article previously posted, AST Space Mobile is also working on a satellite design that "talks" directly to terrestrial smartphones.
Like the SpaceX scheme, it doesn't require any software or hardware upgrades to the smartphones.
Unlike the SpaceX scheme, there is no plan to deploy up to 30,000 of them.

This is great news. I am curious as where all these SpaceX satellites will be made in what state??? EM, SpaceX and Tesla does it better. Amazing good show.
