Location Transport

Can police track or trace a cell phone to its exact location?

Imagine you are in an unfamilar place, and a group of people are about to jump (fight) you. If you call 9-1-1 from your cell phone and then just put in back in your pocket, while it is still one, will police be able to locate your EXACT location?

  1. actually yes. Your cellphone sends out a ping to cell towers every 5 to 15 minutes. By this ping,you can be located by triangulation.
  2. Like someone else answered, your phone can be "pinged" and triangulation is used to determine your location. However it's not able to find your "exact" location. It will determine an area that you are in and will take some time to determine. You are looking at a minimum of 20-30 minutes. And I'm guessing by then the fight would be over. Also realize that in some areas, such as nearly the entire state of California dialling 911 from a cell phone sends your call to California Highway Patrol, not your local Police. And if your in California you know that getting a 911 operator from CHP takes a loooong time. Better to always know where you are and yell out for help. Or program the non-emergency dispatch phone number of your local PD into your cell phone. Call that number if you're in an emergency situation.
  3. Yes...
  4. The information that you're getting is info that is available to the public. Your location within a few meters can be determined but it can take a little while and the accuracy can depend on your cell phone carrier and your phone. There is technology in this matter that would surprise you but the law enforcement agency has to go through the cell phone carrier and that takes a little while. 911 does not have the capability to determine your location. Your phone is constantly searching for a new tower with a better signal. That's why if you're in an area where you have poor coverage, your phone battery will not last long.
  5. That's how Law Enfarcement caught O J Simpson. Cell phones, computers and the like are less secure than a simple post card!
  6. yes. they have trackers
