Does the iPhone have a GPS system?
iPhone 1st generation does not have built in GPS, but iPhone 3g has a built in GPS module. However, when GPS is not available, iPhone 3g will also use cell towers to triangulate your approximate location.
Does AT and T 3G use cell towers or satellite?
All cellular data networks rely upon cell towers. Mobile devices are not equipped with the proper radios or devices to "talk" to satellites. Functions like GPS are still "assisted," meaning that the satellite refers data to the cell tower which in turn sends data to the mobile device.
What do you use artificial satellites for?
I use artifical Satellites for making phone calls on my cell phone, and for navigating through unfamiliar cities with my GPS.
What is radar communication?
Radar communication is electronic communication without the use of wires. Radar communication can be between a ground terminal, like a cell tower, and a satellite. Or it can be between ground towers and also between two or more satellites.
Whey are phones called cell phones?
Because they use cell towers to transmit calls.
Would walkie talkies work if there were no radio or cell phone towers or satellites?
Yes they would. Most walkie-talkies use simple transmit and receive circuits. They would certainly work over a limited distance. However - if greater range were needed, the signal would rely on a system of relay towers.
What does position have to do with Global Positioning System?
GPS provides position/location information. It is similar to that the phone company can track you phone location with the signal strength received by at least 2 cell phone towers. If only one cell phone tower, the phone signal can only be interpreted as that the phone is somewhere in the circle of a known radius, assuming at ground level. With two cell phone towers, the phone signal can be narrowed to two possible locations. With three cell phone towers, the phone location is narrowed down to a small region, say within a city block. In the GPS, the cell phone towers are replaced by satellites. A hand-held GPS unit can use the signals from 4 satellites to calculate the coordinates (x,y,z) of the location and also how fast the unit is moving.
Do you have to unlock every iPhone?
No. You only need to unlock an iPhone if you want to use a different cell phone company with your iPhone.
Does boost mobile use sprint cell towers?
absolutly not they use gay nextel old rusty towers, cricket use ther own towers and when roaming sprint so crickets better 100 percent
Can you use your cell phone when you stay on Mars?

What cell company does the iPhone use?
Verizon, Sprint, and AT&T
What cell phone does Troian Bellisario use in real life?
