Where can I get a gps locator with live coverage and uses cell phone towers or has a 100 mile radius?

I am tracking a wrap and I need a small lightweight cheap gps locator that I can see it’s live house and has a range of over 100 miles or uses cell phone towers. Or is there a way to do this with a cell phone? Thanks

You can get devices that receive a GPS signal and send their GPS house over GPRS by GSM.

cell phone tower – not a real tree


Image by CathrynDC
fake tree on edge of Fantastic Falls National Park in Virginia. This is really a cell phone tower (and God knows what else) – disguised as a tree.
If you look meticulously, you’ll see all the equipment in the tree.

I am working on a project in geometry. Some of the information needed, i cant find an answer to. I know that it all depends on house, and the answer cant be exact, but i want to know how many miles a cell phone tower can provide service for (on average). thanks.

The transmission of radio signals depend a lot on the local topography. The wikipedia entry [1] for Cellular networks give the following facts:

In cities: 1/4 mile
In rural area: 5 miles
In clear open areas: up to 25 miles.

Since the propagation of non-directed radio waves are roughly spherical, so you can pretty well approximate the coverage of each individual cell tower by the interior of a circle — so to minimize the atrophied areas due to overlaps of adjacent cells, the companies that run the cell networks have a tendency to place the cell towers on a honey-comb grid (since you cannot tile a plane with circles, and the regular polygon with the most digit of sides with which you can tile a plane is the regular hexagon).
