Dangerous Radiation From Hidden Cell Phone ... in the microwave region above analog cell phones ... and tribulations regarding cell phone and tower RF ...
To get back to what I was saying above. GPS satellites combined with Microwave relay towers, combined with phone lines all over the world work in concert to make your cell phone calls to other cell phones on earth or to other land line phones as seamless as possible.
First of all, your cell phone or smart phone (same technology for calling pretty much) sends out a ping as a locator beacon which says to the cell phone towers basically ("i'm here at this location right now!") which means, "I'm ready to receive or send a call and I'm such and such a number.)
(I bet you wondered how phones are located all over the world.) Computers keep track of the location of any phone turned on that is a cell phone or smart phone on earth in this way. If the phone is turned on and it is within receiving range of a cell tower this is what is happening worldwide with all cell phones turned on and charged up.
So, whatever nation you are in when your cell phone is on knows your exact location within 3 feet 24 hours a day whenever your cell phone is turned on and charged up enough to send out a "Ping" locator.
So, the computer servers keep track of this location of each turned on cell phone or smart phone worldwide. So, the computer servers can communcate with each other worldwide as to that location if a call is placed.
So, let's say you are in the U.S. on top of a mountain and call another country. So, the signal ping goes to the cell phone tower nearest you and says to the tower and computer server connecting it, "I want to make a call?" and the computer server says, "What name and what country and what number to do want to call?" Then the number goes through and that cell phone or land line you want to call is found in the country you are calling through whatever cell phone tower that cell phone or smart phone is connected too.
Then because of digital sound amplifying your signal is easier over that distance than it ever was with analog signals. So, even 5000 or 10,000 miles away often your call is as clear (even if a little bit tinny) because of digital sound and the way it can be reclaimed and resent over computers as zeros and ones in digital format.
So, even though it might not be as clear as normal speech you likely still will understand what is being said to you worldwide even from one top of one mountain to the top of another mountain 10,000 miles away.
This is the simplest way I could explain all this without going into too much technical detail.
