How accurate is cell site analysis?

In some instances Cell Site Analysis can be accurate to a few metres, or sometimes a few streets (approximately a postcode).

Is cell site enough evidence?

Cell site analysis recognises where data was used, when it was used and who used it – and as multiple mobile phones are usually present at the scene of a crime, cell site data can provide a vital, convincing piece of evidence in a criminal investigation and have a significant impact on a legal case.

How does cell site evidence work?

Cell Site Analysis is a means of establishing the geographical location of a mobile phone when calls, SMS messages or data is sent or received. Evidence obtained from Cell Site Analysis can be combined with other evidence such as CCTV, call data records or observations.

Can cell site analysis tell you exactly who owns a mobile device?

By analysing the time and date at which a mobile device connects to a cell site, it is possible to determine the movements of the device owner. Geographical mapping with cell site analysis can also be used to confirm or disprove an alibi.

Is cell tower triangulation precise?

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.

What is cell site location data?

Cell site location information, in turn, is the recorded information noting particular points in time when radio signals bounce off a given tower over a specific time frame. That information is used to estimate the location of an individual by identifying the nearest cell tower and sector used while a call occurs.

What is Cell Site analysis?

Cell Site Analysis is a technique used to determine which cells a mobile telephone is likely to connect to given the features and behaviour of the mobile network at a particular geographical point or region of interest.

What is Cell Site location information?

What is a cell azimuth?

Each cell site has an identifier which is recorded when a phone call (or a data call) is made. Furthermore, most cell sites have three aerials each covering a 120 degree arc, called an azimuth. A site survey of areas within that arc will produce data showing which areas have a signal that communicates with that cell.

How does cell site work UK?

How does Cell Site Analysis work? Each time a phone connects to the network, for a call or text message, one of the many antennas attached to telecommunication masts around the country are used. Cells have service areas and these areas overlap to enable phones to move without disconnecting from the network.

How can you avoid cell tower triangulation?

How to Prevent Cell Phones From Being Tracked

1. Turn off the cellular and Wi-Fi radios on your phone. The easiest way to accomplish this task is to turn on the “Airplane Mode” feature.
2. Disable your GPS radio.
3. Shut the phone down completely and remove the battery.

How accurate is cell-site locator data?

The use of historical cell-site locator data is different than real-time triangulation of three cell towers to locate a phone, or GPS technology using satellites. The accuracy of those technologies is not in dispute, but phone companies do not save GPS or triangulation data for an individual phone — so that information is not used as evidence.

How many agents does the FBI have for cell site analysis?

The agency wants to expand its full-time team of 32 agents dedicated to the analysis of cell-site data, and it has trained more than 5,000 state and local police investigators in the basic methodology.

How accurate are cell-site simulators apps?

Apps for identifying the use of cell-site simulators, such as SnoopSnitch, may not be verifiably accurate. Some more advanced tools have been built, which may be more accurate. For instance, security researchers at the University of Washington have designed a system to measure the use of cell-site simulators across Seattle.

Can law enforcement collect cell site location data without a warrant?

Here, Carpenter points to states that require a warrant before law enforcement can collect cell site location data, as well as 47 U.S.C. 222 (c) (1) which states that cell service providers may not disclose location information without customer approval.
