It was once that determining accurate location with GPS Global Positioning System technology required acquiring expensive and complicated hardware and software. Now, extensive solutions can be found through cellular service suppliers and the newest cell phones.
The tracking software on a cell phone usually need to be enabled by the user. Based on the mobile phone, the software may persist – remaining enabled as soon as the phone is activated following being powered down. This function may be especially helpfull if mobile phone tracking is relevant and you do not want to need anyone using the cellphone to turn monitoring off and on.
As somebody travels from one cell tower to a new one, the cell base stations monitor the strength of the cell phone’s signal. As the mobile phone moves toward the edge of one cell, the signal strength diminishes. At the same time, the next radio base station in the cell being approached measures the strength of the signal increasing. As cell phones move from cell location, to cell location, the towers transfer the signal from one to another location. In remote locations, cellular towers may be too far apart to provide a consistent signal. Even when cellular towers are plentiful GPS satellite signals may be interfered with by tall buildings, trees, clouds or mountains. Signals really don’t get to building interiors adequately and sometimes everyone has trouble obtaining clear signals inside buildings, specifically in elevators. Even without having a GPS receiver, or every time a satellite signal is not available, mobile phones may give information regarding cellphone position. This kind of technique of calculating handset location is named Triangulation or Mobile Location Services (MLS). Cell Tower Triangulation utilizes signal examination data, which includes signal strength, to determine the time it takes signals to go from your telephone to no less than three cell towers to estimate precisely where it is. There are numerous factors influencing estimates and this method is often much less reliable than GPS measurement.
An additional thing relevant to Tracking Application “Persistence” and cell phone GPS tracking is the possibility of wasting the battery. It desirable to be able to remotely modify the frequency of taking GPS position. Choosing real-time or periodic sampling affects both the resolution of finding location as well as battery life. One typical way of controlling battery and data use is Passive Tracking. Some cell phone GPS tracking devices will store location data internally so that it can be downloaded when convenient. Also known as “data logging,” it may maintain location information regardless if the device has traveled beyond your wireless network. Passive tracking is not a general function built-in to standard cell phone, but the most recent mobiles often have Passive tracking capability.
