Q, your post does not make sense. mobile phone signals are not passed through satellites. Towers and land lines transmit the data and voice services.. why would you say satellites relay mobile phone signals to end users??

Actually, I have been digging it for a while now because I didn't know how it worked.. but I'm finding that cellular communication is VERY different than satellite communication.

Actually, they're not. The signal passes through cables that are under the ocean. That's how near zero latency works. Those cables also pass internet signals as well. Not satellites.

can you provide me a link? I'm not doubting you, but after looking at this for a while I'm really interested to read about how it works. I am not finding a connection between cellular phones and satellites in everyday usage. The way I read the Q post is that it's a requirement for regular users and the info I am finding doesn't support that notion.

Yeah.. it says "What [3] scientists were killed who were researching the SAT relay of mobile phone signals to end users?"

Don't think so.. most of the info I've read says that your cell provider sends the GPS signals to you through their network.. so they connect to GPS and relay the info to your phone on your data plan rather than a stand alone (i.e. garmen, tom tom etc.) unit would.

Sat comms work on satellite phones. However, a cell phone is a LOT different than a satellite phone. Satellite phones are used by military and first responders in areas that don't have cell coverage. Completely different than what I'd consider a "mobile phone". They sure as hell aren't iPhones, Samsung, Etc.

I did find info that says the telephones on airplanes use satellite.. remember back on 9/11/2001 where they said that people were using their cell phones to call loved ones to tell them they were about to die? Yeah, that was a lie. The technology back then didn't work. And I've taken my phone on planes and never put it in "airplane mode" and it loses signal about 1,000ft off the ground.

100% From the midwest USA, I have been able to talk to Chile and Argentina on 10 watts and a speaker wire ground plane antenna strung up between trees in my backyard. I've been a ham for a long time. 73s!

It does say that they were "researching".. I guess I was reading it as if it were already a technology that we were using. That makes sense. Otherwise, if Q was implying that it's something that is already used I would really question why he/she/they would make that statement.
