Mobil phone tracking
Localization may be effected by a number of technologies, such as using multilateration of radio signals between several cell towers of the network and the phone, or simply using GPS. To locate a mobile phone using multilateration of radio signals, it must emit at least the roaming signal to contact the next nearby antenna tower, but the process does not require an active call. Mobile positioning may include location-based services that disclose the actual coordinates of a mobile phone, which is a technology used by telecommunication companies to approximate the location of a mobile phone, and thereby also its user.
The location of a mobile phone can be determined using the service provider's network infrastructure. The advantage of network-based techniques, from a service provider's point of view, is that they can be implemented non-intrusively without affecting handsets. Network-based techniques were developed many years prior to the widespread availability of GPS on handsets.
The technology of locating is based on measuring power levels and antenna patterns and uses the concept that a powered mobile phone always communicates wirelessly with one of the closest base stations , so knowledge of the location of the base station implies the cell phone is nearby. Advanced systems determine the sector in which the mobile phone is located and roughly estimate also the distance to the base station.
Further approximation can be done by interpolating signals between adjacent antenna towers. Qualified services may achieve a precision of down to 50 meters in urban areas where mobile traffic and density of antenna towers base stations is sufficiently high . Rural and desolate areas may see miles between base stations and therefore determine locations less precisely.
GSM localization uses multilateration to determine the location of GSM mobile phones, or dedicated trackers, usually with the intent to locate the user. The accuracy of network-based techniques varies, with cell identification as the least accurate due to differential signals transposing between towers, otherwise known as "bouncing signals" and triangulation as moderately accurate, and newer "advanced forward link trilateration " timing methods as the most accurate.

The accuracy of network-based techniques is both dependent on the concentration of cell base stations, with urban environments achieving the highest possible accuracy because of the higher number of cell towers , and the implementation of the most current timing methods. One of the key challenges of network-based techniques is the requirement to work closely with the service provider, as it entails the installation of hardware and software within the operator's infrastructure.
Frequently the compulsion associated with a legislative framework, such as Enhanced , is required before a service provider will deploy a solution. The location of a mobile phone can be determined using client software installed on the handset. In addition, if the handset is also equipped with GPS then significantly more precise location information can be then sent from the handset to the carrier. Another approach is to use a fingerprinting-based technique,    where the "signature" of the home and neighboring cells signal strengths at different points in the area of interest is recorded by war-driving and matched in real-time to determine the handset location.
This is usually performed independent from the carrier. The key disadvantage of handset-based techniques, from service provider's point of view, is the necessity of installing software on the handset. It requires the active cooperation of the mobile subscriber as well as software that must be able to handle the different operating systems of the handsets.

Google Maps. One proposed work-around is the installation of embedded hardware or software on the handset by the manufacturers, e. This avenue has not made significant headway, due to the difficulty of convincing different manufacturers to cooperate on a common mechanism and to address the cost issue. Another difficulty would be to address the issue of foreign handsets that are roaming in the network.
The type of information obtained via the SIM can differ from that which is available from the handset. For example, it may not be possible to obtain any raw measurements from the handset directly, yet still obtain measurements via the SIM. Crowdsourced Wi-Fi data can also be used to identify a handset's location. Hybrid positioning systems use a combination of network-based and handset-based technologies for location determination. Both types of data are thus used by the telephone to make the location more accurate i.
Alternatively tracking with both systems can also occur by having the phone attain its GPS-location directly from the satellites , and then having the information sent via the network to the person that is trying to locate the telephone. In order to route calls to a phone, the cell towers listen for a signal sent from the phone and negotiate which tower is best able to communicate with the phone. As the phone changes location, the antenna towers monitor the signal, and the phone is "roamed" to an adjacent tower as appropriate.
By comparing the relative signal strength from multiple antenna towers, a general location of a phone can be roughly determined. Other means make use of the antenna pattern, which supports angular determination and phase discrimination. Newer phones may also allow the tracking of the phone even when turned on and not active in a telephone call.
This results from the roaming procedures that perform hand-over of the phone from one base station to another. A phone's location can be shared with friends and family, posted to a public web site, recorded locally, or shared with other users of a smartphone app. The inclusion of GPS receivers on smartphones has made geographical apps nearly ubiquitous on these devices.
Specific applications include:. In January , the location of her iPhone as determined by her sister helped Boston police find kidnapping victim Olivia Ambrose. Locating or positioning touches upon delicate privacy issues, since it enables someone to check where a person is without the person's consent.
In Malte Spitz held a TED talk  on the issue of mobile phone privacy in which he showcased his own stored data that he received from Deutsche Telekom after suing the company. He described the data, which consists of 35, lines of data collected during the span of Germany 's data retention at the time, saying, "This is six months of my life [ Spitz concluded that technology consumers are the key to challenging privacy norms in today's society who "have to fight for self determination in the digital age.
China has proposed using this technology to track commuting patterns of Beijing city residents. You can know the GPS coordinates of a phone number within seconds. If you have lost the subscriber identity module Sim Card. It is possible to provide the last location of a phone, because modern devices are equipped with global positioning system receivers that are constantly connected with the satellites. It means that the process of data-exchange that provides the information required for the adequate mathematical equations is constantly running.
It can easily calculates the distance between the phone and satellite, and run a trilateration that will provide a very precise location. But you can check the last location if you have access to the center of call data related to the subscriber. The user should be aware of his legal position before using this platform.
Everyone person has its privacy rights. If you lose your phone, you should know that it is crucial and very important to take action very quickly. Every lost minute increases the probability of never finding your phone again. If someone stole your phone, you will not be able to locate it if the perpetrator disables the subscriber identity module card linked to your phone. In this case, you can only get the latest saved location, going through the positioning history and that only if the phone was connected to the mobile network.
The person that is holding your phone can block the data-exchange process by using some apps that interfere with the signals.

Our system can identify and give an accurate estimation of the real-world geographic location of a device, using its number. The subscriber identity module is constantly receiving signals from a satellite; the transmitted data is processed afterwards to generate an approximate location. Using a positioning system can enhance the usefulness and accuracy of the geolocation.
Internet and phone geolocation can also be performed by combining a geographic location with the IP Adress It can include information: Country, region, city, time zone and other encrypted data. It also governs the frequency of data reception and coordinates all cell actions. Without it, there would be no gps receptor able to translate the encrypted data and interpret it on a geographical map. If the distance that separates, your mobile from the tower is important, the global positioning system intermediate can find some difficulties in generating accurate location.
The other factor is the obstruction of objects surrounding the device. In fact, some materials can affect badly the performance of the system as they naturally block the transmission of signals. Before launching the system, we ran multiples tests to determine a margin of error, and estimated interval of how the system performs under bad circumstances. Fortunately, the results were very satisfying and we figured out that with the help of our modern technology, there was no real obstacle that could compromise the effectiveness of our number tracker.
