10 Free Apps to Track a Cell Phone Location for Free

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.

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, [6] [7] [8] 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.

Smartphones

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. Here you get complete details of the complete mobile number.

Smartphone GPS does not use satellite data directly, relying instead on cell tower triangulation to plot locations on the unit's online map. However, as long as the phone is within range of cell towers and is getting signal, the GPS functions work. However, should your child end up out of range of any cell reception, these functions will not operate as intended.

This is critically important, especially if you know your child will be traveling to rural locations, on a camping expedition or heading overseas on a class trip. Apple's logically titled "Find My iPhone" requires the app to be installed on your kid's phone.
