Phone Tracking – Identifying Cellular Phone Location Isn’t Going To Always Have To Have GPS
<p>The desire to Track Cell Phones Location, or what’s often known as Trace Mobile is actually well established for everything from public safety, child protection, elder care, workforce monitoring and even relationship monitoring. Nowadays, GPS enabled phones are actually regular gear, but GPS signals are certainly not always accessible. If satellite signals are not available, or accuracy and precision is less important than battery life, utilizing Cell-ID is a useful alternative to GPS mobile phone location. The position of the device might be determined by the cellular network cell id, that pinpoints the cell tower the phone is connected to. By knowing the location of this tower, you may know approximately the location where the device might be. Nonetheless, a tower can cover a massive area, from a few hundred meters, in higher population locations, to several miles in lower density areas. This is why location CellID accuracy is lower than GPS accuracy. Nevertheless location from CellID still presents quite a viable alternative.
Another method of Cell Phone Location Tracking is Triangulation or Mobile Location Services (MLS). Cell Tower Triangulation employs signal analysis data to determine the time it takes signals to travel from your cellular phone to no less than 3 cell towers to determine location.
To help conform to Federal Communications Commission guidelines, cellular phone companies are required to be able to provide authorities with cell phone latitude and longitude to an accuracy of 50 to 300 meters. Cell Tower Triangulation does not always meet this requirement. By way of comparison, commercially available GPS systems will be able to realize precision right down to 3-10m. This depends upon many factors, as GPS signals tend to be rather weak and they are disturbed by many environmental factors. With Mobile Location Services (MLS), the GSM cell network provider utilizes triangulation techniques to estimate the location of the cell phone, its accuracy is proven to be much worse than that of GPS. MLS is also affected by the same issues as GPS in the sense of the barriers impeding signal quality and the density of GSM towers to help in the triangulation effort. In remote areas location accuracy may be off as much as a mile.
Generally speaking it comes down to what location tracking system is obtainable, as well as the need for accuracy. Hybrid methods are emerging that use various techniques in tandem to provide best available location given available resources. It may be important to consider how GPS location software applications handle the data and controls mobile phone settings including options of using real time tracking on demand, or preferring to minimize battery use and data transmitting. Generally the software establishes the position with a GPS receiver and transmits the tracking data to a server through a cellular packet data connection. The data connection to the server is usually made using the internet. The frequency of GPS sampling and how frequently and by just what technique the data is sent to the server affect usefulness and possibly costs.
