"R," is you. I probably should have put "Z" of "H," but I guess I saw the "R" in Ranch Hand. I am cm, or CactusMitch.
How do you prefer to be addressed? realize that you name is not on this "REPLY" screen and there are potentially others in the discussion.
I presume that in the USA, the Federal Communications Commission maintains a public list of cell tower locations,, i.e. LAT and LON. Getting the location of the towers from a handheld device might be possible by collecting the signal strength against a record of the location of the handheld device as it explores the area as recorded from some other source of location information like a map or GPS. Then there is the trigonometry. Sounds like going around the barn to get to the door.
Do you want to find the location of the tower, or the location of the device relative to the tower? The direction to go to get a better signal?
I am working on a project to find the the Android device relative to the proximate entries in a big database of locations.
