# Quick Answer: How Does Cell Phone Triangulation Work?

## How does signal triangulation work?

Triangulation is a process by which the location of a radio transmitter can be determined by measuring either the radial distance, or the direction, of the received signal from two or three different points.

Triangulation is sometimes used in cellular communications to pinpoint the geographic position of a user..

## What is an example of data triangulation?

Data triangulation involves the use of heterogeneous data sources, for example, qualitative and quantitative. Alternatively data may be gathered (using the same method) from different sources or at different times, for example, the pre-‐ and post-‐use of a questionnaire.

## How accurate is cell phone pinging?

According to experts interviewed for its story, a phone can be up to 20 miles away when it “pings,” or connects with, a cellphone tower. … Many investigators argue that cellphone connection data can be quite accurate. Yes, in some instances. But it also can be quite in accurate.

## What is the process of triangulation?

In surveying, triangulation is the process of determining the location of a point by measuring only angles to it from known points at either end of a fixed baseline, rather than measuring distances to the point directly as in trilateration.

## What is an example of triangulation?

There are four common forms of triangulation: (1) data triangulation means that the ethnographer uses a variety of data sources for the study, for example, a range of different informants; (2) method triangulation means the use of multiple methods in the same project (Janesick, 1998), for example, interviews and …

## Can a phone call be traced to a location?

They can’t hide it from the phone company. … The location of a cell phone caller is equally easy to trace, thanks to a 2006 order by the Federal Communications Commission that requires cell phone networks to feature location-tracking technology such as GPS chips to assist 911 services.

## Why is triangulation used?

Triangulation facilitates validation of data through cross verification from more than two sources. It tests the consistency of findings obtained through different instruments and increases the chance to control, or at least assess, some of the threats or multiple causes influencing our results.

## What are the four types of triangulation?

In 1978, Norman Denzin identified four basic types of triangulation: (1) data triangulation: the use of multiple data sources in a single study; (2) investigator triangulation: the use of multiple investigators/research- ers to study a particular phenomenon; (3) theory triangulation: the use of multiple perspectives to …

## Can police trace a cell phone?

In most of the United States, police can get many kinds of cellphone data without obtaining a warrant. Law-enforcement records show, police can use initial data from a tower dump to ask for another court order for more information, including addresses, billing records and logs of calls, texts and locations.

## What is the most common type of triangulation?

Data TriangulationThere are five types of triangulation: Data Triangulation Data triangulation involves using different sources of information in order to increase the validity of a study. This type of triangulation, where the researchers use different sources, is perhaps the most popular because it is the easiest to implement.

## What is meant by triangulation?

a technique for establishing the distance between any two points, or the relative position of two or more points, by using such points as vertices of a triangle or series of triangles, such that each triangle has a side of known or measurable length (base, or base line ) that permits the size of the angles of the …

## Can 911 track a cell phone?

Historically, 911 dispatchers have been unable to track the locations of callers on cell phones as accurately as those calling from landlines. … This location information must be available for at least 50% of wireless 911 calls, a requirement which increases to 70% in 2020.

## How can you avoid cell tower triangulation?

You can only turn off all location (like cell-tower triangulation) by turning off your phone.There are location services in modern phones based on Wifi, cell towers, and GPS. … For land lines, each one terminates in a location known to the phone company. … So if your phone’s on, this location finding is possible.

## How accurate is cell tower triangulation?

Most often this is done through triangulation between radio towers. GPS accuracy varies and could incorrectly place the victim’s location at their neighbor’s home. … By using cell tower triangulation (3 towers), it is possible to determine a phone location to within an area of about ¾ square mile.

## Do cell phones use GPS or triangulation?

GPS is a radio navigation system. It uses radio waves between satellites and a receiver inside your phone to provide location and time information to any software that needs to use it. … Your phone’s GPS receiver uses the data from these signals to triangulate where you are and what time it is.

## How long does it take to triangulate a cell phone?

The actual time it takes to track a mobile phone device is two seconds. You can track a mobile phone device using only one cell, but it’s only going to be able to provide a general location. Use two cell’s will provide an approximate location within a few hundred yards.

## What is triangulation method in surveying?

Triangulation. … Triangulation is a surveying method that measures the angles in a triangle formed by three survey control points. Using trigonometry and the measured length of just one side, the other distances in the triangle are calculated.
