The turn of the century has not seen a bigger invention than the mobile phone; hand-held communication devices are possible due to the advancement of the wireless technology. Those frequency bands which were once the domain of the defense systems have now been made available to the common public. The mobile phone is an extremely useful device which enables people to be in touch over long distances; we are reachable where-ever we may be travelling, even if we are not stationary but moving in say; a car, train or an airplane.
The mobile manufacturing companies over the world have introduced ‘mobile tracking systems’ for cell phones. We may be traveling, but our family can know our location exactly. Also we can know if we are heading in the right direction towards our destination. Locating children or pets has become easier, and this technology has become one of the break-through technologies prevalent in the mobile industry today.
The Localization Technology:
This technology is available either by downloading some paid software or through a free localizing cellphones’ technology, online. It is based on the measurement of power levels, and antenna network configuration. It works on the principle that a powered mobile interacts wirelessly with the closest base station and so it can be deciphered that the mobile is in the vicinity.
The more advanced techniques work on the fact that the mobile is functional in a particular geographical area, which is at a stipulated distance from the base station. By interpolating signals between antenna towers, we can further approximate the exact location of the mobile, up to 50 meters.
The localization technologies for mobile phones are as follow –
1) GSM localization – This technology can be a used as a free localizing cellphones’ technology; it uses multilateration for locating GSM mobile phones.
2) The GPS based technique – This uses a constellation of 27 satellites orbiting the Earth, the user has a GPS receiver in his mobile phone, which needs a direct line of sight available between the device and any four of the satellites. Data can be downloaded on the device for navigating through an unknown area.
3) Network based Techniques – These are based on the service provider’s network, which is used in the identification of the mobile phones’ location; this system is advantageous because it does not affect the handsets. There are sub-techniques like the cell identification; that is not very accurate, the triangulation; that is moderately accurate, and the ‘forward-link’ timing method; that is the most accurate. The accuracies of these techniques depend on the base station cell concentration, the urban environments being the most conducive. The only drawback of this system is that it is highly dependent on the network service provider and the quality of the software and the hardware of their infrastructure installations.
4) Hand-set based technologies – There is a need of software to be installed into this device, some of which are freely available online, making this a free localizing cellphones’ technology. This system identifies the cell and signal strength of the home cells and cells in the vicinity; this information is continuously relayed to the carrier. Mobile phones that work on the Android and iOS platforms can download the ‘Google Maps’ application for cell location.
5) The SIM based technology – In this, each mobile sim has a unique identification code, which is located by certain software applications.
6) Wi-Fi-based technology – In this, the data needs to be collected by crowd sourcing and can be compiled to be used for cell localization. Some manufacturers have designed Wi-Fi positioning systems and indoor positioning successfully.
7) The Hybrid technology – This uses a combination of the GPS and Network-based techniques.
Free Online Trackers:
A lot of information is available online which helps enthusiasts identify free technologies and methods of localizing mobile phones; websites like trace.me, track.Me, gpsphonetracker.org, lookout.com and trackapartner.com are some of the free mobile tracking sites available on the internet.
