A Mobile Phone is really a contemporary and enhanced two-way radio. Obviously they don’t work without help and are part of a cell network. At the heart of the system are towers and base stations, placed into a network of cells, that send and receive radio signals. Cell phones include low-power transmitters that connect with a nearby tower.
The tracking software on a handset commonly need to be permitted by the user. Relying on the mobile phone, the application may persist – remaining enabled whenever the phone is activated following being powered down. This particular attribute might be especially usefull if phone tracking is important and you don’t want to need the person using the cellphone to turn tracking on and off.
As anyone moves from one cellular tower to another, the cell base stations monitor the strength of the smart phone’s signal. As the mobile phone moves toward the edge of one cell, the signal strength reduces. At the same time, the next cell base station in the cell being approached measures the strength of the signal strengthening. As mobile phones move from cell postion, to cell location, the towers shift the signal from one to the next. In remote locations, cellular towers can be dispersed too much to offer a consistent signal. Even when cellular towers are abundant GPS satellite signals could be impeded by tall buildings, trees, clouds or mountains. Signals do not get through to building interiors very well and sometimes people have trouble getting clear signals inside buildings, specifically within elevators. Even without a GPS receiver, or when a satellite signal is not available, cell phones can supply specifics of telephone location. This particular process of computing mobile phone location is generally known as Triangulation or Mobile Location Services (MLS). Cell Tower Triangulation employs signal examination data, such as power, to determine the time it takes signals to travel from the mobile phone to at least three cell towers to determine exactly its position. There are many variables impacting estimates and this method is naturally much less accurate than GPS measurement.
One more issue pertinent to Tracking Application “Persistence” and handset GPS tracking is the possibility of battery drain. It is very important to be able to remotely modify the frequency of taking GPS position. Choosing real-time or periodic sampling affects both the accuracy of finding location along with how long the battery will last. One typical means of controlling battery and data use is Passive Tracking. Some mobile phone GPS tracking devices will record position data internally so it can be downloaded later. Also known as “data logging,” it may keep position data regardless if the device has traveled outside the wireless network. Passive tracking is not a universal feature built-in to standard cell phone, but the most recent mobile phones often have Passive tracking capability.
