Strictly speaking, GPS devices are passive and don't transmit anything (correlating received signals from a constellation of satellites). Many cellphones use Assisted GPS, sending GPS information to servers to improve positional accuracy (sent through the encrypted data channel). Breaking this encryption is non-trivial (only GSM is known to have a vulnerability). Therefore, it is practically impossible to use a program to externally monitor GPS or AGPS signals. However, many phones offer programs to monitor position on the phone (for example, the iPhone'sMaps application).
No. without a signal it is impossible. If a stolen computer is turned on though, that is the only way the signal can be found. Same thing with cell phones.
There are cell phones and free online tracking available. The program for it is called gpsED.
yes there are although the signal there is not the best.
The cellular signal booster works well with basically all cell phones. It is designed to improve your signal and reception, so it will be especially beneficial if you live in a rural area.
The absence of the GPS on the normal phones make it hard to track the cell phone.
Yes there is. This cell phone is known as a blackberry. These phones come with apps that allow you to GPS track. This app can go either way, to be tracked or to track.
Cell phones are used to see e-mails and to keep in track
It could track people if the person has something that has a G.P.S. thing on it, like a cell phone. Most cell phones have G.P.S, so if you have a cell phone people could track you.
If Credit cards or data was exchanged during the purchase.
VoIP phones differ from cell phones primarily in that they connect through the internet, rather than via a cell signal. Therefore they do not require any additional phone plan as all the data is covered by your internet plan.
yes because they can now if they are in danger
yes you can use your phones or other devices in the dessert as long there is a signal
